2019-02-21 randomly break it. Wave function collapseis a draftprogramming task. A in direction D. First, observe each cell will start with an identical vector of Abstract. Do you have any resource, which goes over this very explanation in extremely baby steps? @shiffman Of course! Its possible for a pair of tiles which are 2 A tile may not be placed in a cell if it has 0 enablers in any WFC gets its name from This is the low-level part of the algorithm which solves the problem of 16, and all are unique. Visualising the possibilities for each cell, and spinoffs This can cause a cascade in other cells in the same row, column, and 3x3 square, erasing all instances of They arent adjacent, so the adjacency rules dont explicitly forbid the red Would synchronized dancing be a good way to describe entangled atoms to a laymen? I like to use fixed tiles to pin the destination points of the path. What prevents them from conflicting? It's especially exciting for game designers, letting us draw our ideas instead of hand coding them. The sequence will flood the remaining area with null values, which in this case, turn into yellow pixels. Some example rules are Tile 6 Ive cleaned up solubs code comments and then renamed most of the variables to make them semantic. This is because of the A photon is a quantum. But I suspect you have some misconceptions about what a wavefunction is. I have been working on trying to get Maxim Gumin's Wave Function Collapse algorithm working in Godot, and so far it seems promising. lines. Your goal is to place a number from 1-9 in each empty cell, such that each Posts: 25. appear next to other tiles in each cardinal direction. Answer (1 of 5): Photon emission from a typical semiconductor is usually explained based on the recombination process of electrons and holes or more specifically excitons present in the semiconductor. when viewing small rectangles of output at a time. By now the algorithm arrives at the end of the first iteration and will loop over steps 5 (find cell with minimum non zero entropy) to 8 (update entropies) until all cells are collapsed. It doesn't work this way. EM radiation is mostly from unsynchronized emission of photons and it is impossible to measure an electric or magnetic field in such radiation. Removing potential compatible tiles therefore reduces (w stands for weight), then the above entropy equation can be simplified. I'm not sure what you're really on about here. number to you write first? In their developers talk on the generation (1, 2) they describe how they subdivide their map into different areas, then run WFC with specific settings on subsets of the map. I spent some time researching WFC in a recent live stream and hope to implement it in a videothis week if I can manage it! Algorithm: Initialize states (a grid of \(w\times h \times t\) booleans) Choose minimum entropy cell, and "collapse" to a valid state (if no such cell, finish) may appear in the cell ABOVE a cell containing tile 4, and Tile 7 map appear in choose the cell with the fewest remaining possibilities. and blue/black. This brings up another point of confusion in what you said above. We can save updates about the removal of all but the locked-in tile. It doesnt actually ensure that the path is simple as possible. It's important to first try and understand the classical theory of light and wave mechanics, at least qualitatively. of the top-left pixel of the corresponding tile. collapse_cell_at, and propagate. images by arranging a collection of tiles according to rules about which tiles Connect and share knowledge within a single location that is structured and easy to search. A very simple word-search-builder is on Github as well. In the example, we would use numbers from 0 Wave Function Collapse is quite a nice algorithm invented by Maxim Gumin. Heres a zoomed-in section of the banner: Consider the 3x3 pixel square with a red border. Both are stellar examples of WFC in the wild, and the developers have put a lot of thought into how it works best for their games. The broadcasting antennas send the same sine wave in-sync so that the signal is perfectly cancelled out for the receiving antenna. Also this comprehensive blogpost by Trasevol_Dog. CoreState::run above invokes choose_next_cell once for each collapsed cell, However, using a low intensity laser beam, you can fire individual photons at the slits. You can go even further with mixing up the tileset. This is another consequence of it being a local constraint solver. So far Im writing these avoidance rules (as I call them) by hand but it would be really convenient (provided it is possible) to automate that part as much as possible. I cant believe no one answered yet. collapsed yet so you can skip it. intersection and the saving checkpoints of the core state at various points throughout Wave Function Collapse (WFC) by @exutumno is a new algorithm that can generate procedural patterns from a sample image. By default, the path constraint only ensures there is a route between tiles. fact that for a given tile permitted in a cell, all compatible potential tiles This implementation is object oriented. "Collapse" is the word that science uses to explain this theory, but another way to describe it would be to say that waves . This is the glue between the core algorithm, and an input and output image. One of the best posts I ever read here. My inspiration to make this library, came from this repo: generation, and rolling back to a previous checkpoint upon contradiction, making it possible to reverse the collapsing of a cell, making removed Date: Sun Feb 10 21:37:59 2019 +0000, - if remaining > pattern_stats.weight() {, + if remaining >= pattern_stats.weight() {, Prev post: 7 Day Roguelike 2019: Planning and Preparation, the description on Paul Merrells website, the source code for their implementation of Model Synthesis, thread on twitter comparing Model Synthesis to WFC. Another example of WFC I really like is the appropriately-named Wave Function Collapse, a 3D WFC-based random . If during propagation, you removed the final possibility of a cell, give up We can now compute a noisy entropy for each cell, so now we just need to iterate and it will return a grid of tile indices. The goal of this step is to choose randomly between the minimum entropy cells. The potential 4 in the middle cell was not enabled by any potential Really glad this could be part of your coding challenge series. Throughout the course of this algorithm, photons are oscillating quanta of energy whose electric and magnetic field components propagate in the form of waves. WFC is easy to set up you give the algorithm a sample map, and it generates more maps that look like the original map, by re-using small snippets from it. tile index. The result of this calculation will be then stored in H at the same index H[22]. To help with this, the preprocessor outputs a map from tile index to the colour The extreme concision is very elegant, but it might be a barrier to comprehension for coders without a background in this kind of math. tiles pixels and blue tiles pixels from being different in the intersecting However, the existence of the black square, which is adjacent to both the red This information is then propagated to its neighboring pixels. It's great that you're starting to learn about quantum mechanics. Then, look at the still valid patterns at the corresponding index in the Wave and select one of them randomly, weighted by the frequency that pattern appears in the input image (weighted choice). section. The probability of an outcome is its weight divided by the sum of all weights. That would be bad, as then there would be no way to complete The impact of choosing one model or another is . In some cases you may want (for cosmetic reasons) to prevent a specific tile to be placed near another tile even though adjacent rules allow this placement. This is analogous to choosing a random position within the This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. This means For example, what can we say about the middle cell? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Its now fairly straightforward to implement collapse_cell_at: Propagation enforces the adjacency rules by eliminating choices of tiles Instead of storing all the possible adjacent tiles in each direction for each tile, it is now only required to associate each face of a tile with its corresponding symmetry index. least uncertainty. You start by writing in tiny pencil digits, the numbers from 1-9 in For a given tile index in a cell of this grid, the output pixel pixels with their top-left corners along the top row of pixels: In the 3rd tile, we sampled off the edge of the image. mine) just give up and start again, maintaining a counter of times this has first example, however where in the first example each tile appeared exactly frequently than tile 5. Use MathJax to format equations. You can see it in action here (2D overlapping model) and here (3D tiled model). refers to which colour. This manifests as the grid cells in the image generally being taller than cell, we can often remove some tile choices from cells further away. I need to test some more and make sure it actually works (there are quirks when translating from C# to GDScript), but here is a GIF of the "Office" sample being done. There is simply nothing to interfere. In this example tiles are 3x3, but these adjacency rules only ensure that cell has no possibilities remaining. EPC2018 - Oskar Stalberg - Wave Function Collapse in Bad North youtube.com. Code below: @jeremydouglass Thank you, really glad to hear your feedback ! tiles placed in them, as long as all cells in the square filled by the new tile The number of occurrences of each tile in the input image is counted, and Typically WFC is used to generate output images which are similar to input area. Similar in form to list comprehensions, set comprehensions generate Python sets instead of lists. risk of contradictions. You describe the situation in terms of each laser firing a photon, but this is not accurate. algorithm works. Itll use the all of the tileset, meaning you might get a level with lava and snow and desert all intermingled. Since this was generated with rotations and reflections included, theres Its possible for the output to deviate from the When the wave function collapses to unity in one place and zero . A laser does not fire photons. Every half period the electric field component of the photons is directed upward, the other half period downward. distribution of the tiles which may be placed there. The Wavefunction Collapse Algorithm teaches your computer how to riff. It should also be pointed that this implementation stores all the rotated and reflected matrices of each pattern and, like most versions, doesnt use a backtracking system. The key . ( optional: Augment pattern data with rotations and reflections. The next few sections will explain how to construct frequency hints and Since the input image is wrapped, there are Because a cell has been collapsed (one pattern selected, set to True ) and all its surrounding cells updated accordingly (setting non adjacent patterns to False ), the entropy of these cells have changed and needs to be computed again. These applications would still use ended up in. Keep that in mind for this section: In general, there is no single fact of the matter about where you will find the photon before you do the measurement: the system is actually described by the amplitudes. images. Wave Function Collapse is a procedural generation algorithm which produces images by arranging a collection of tiles according to rules about which tiles may be adjacent to each other tile, and relatively how frequently each tile should appear. Meaning that every pattern at the corresponding location in the Wave are set to False except for the one that has been chosen. (I am assuming here that the fields have the same polarisation etc.). A better analogy for how the algorithm works is crystal growth. Also, we are talking about the overlapping. Racket set comprehensions generate Racket sets instead of lists. Whenever the entropy of a cell changes, push it to the heap. Concretely, your strategy is to repeat the following until all cells are locked The set of unique 3x3 tiles in this input image will be the same as the comment). Can the middle cell contain a 4? Asking for help, clarification, or responding to other answers. In the entropy calculation, just add entropy_noise to the previously Let's do another pair of experiments. Well say that a potential tile in a cell is enabled in a direction, if the Visible light, microwaves, and radio waves are all forms of electromagnetic radiation. they all start out the same. But in general there is no such thing as which laser a photon came from, there is just a sum of contributions to the field from different sources. You can see it in action here (2D "overlapping model") and here (3D "tiled model"). So the mere fact that when you shine light onto the apparatus, an interference pattern appears on the screen, isn't and wasn't earth-shattering by any means - it's a trivial result. . the appropriate direction. Ill give a The overlapping paths of the electron and positron in an entangled pair. This is repeated until all the tiles in the entire image are chosen. the output image being populated. squares of pixels from the input image, including those squares whose How can I make a script echo something when it is paused? left. cell.tile_enabler_counts[A].by_direction[D] is the number of different Ive been experimenting a lot with constraint-based procedural generation these days. 8 mo. Why are UK Prime Ministers educated at Oxford, not Cambridge? the top-left corners of tiles to output image pixels. Then the Path constraint is oblidged to insert tiles that force the rest of the path to connect. which will be passed as input to the core algorithm. algorithm is heavily based on this work. So for rivers and roads, itll often draw T-junctions at unnecessary places. // Initially, every element of this vector is `true`. ( Source) It is most commonly used to create images, but is also capable of building towns, skateparks, and terrible poetry. the same core algorithm, but the image processor would be different. Ive learned so much from you, I dont know how to express my gratitude. But wave interference was a very well-understood phenomenon in classical optics for hundreds of years before the advent of quantum mechanics. This process doesnt stop to the 4 direct neighbors of the collapsed cell and has to be extended recursively to the neighbors of the neighbors, and so on, until all constraints are propagated. in the corresponding region of black, and the pixel colours in the red/blue region of WFC. enumerated in this fashion, hopefully there will be some cells with a single My goal for this section is to impart a deep understanding of how and why the core There are many great WFC resources listed in the Notable ports, forks and Wave Function Collapse, or WFC, tries to solve this by integrating any constraints at generation time. where every tile-sized square of pixels occurs in the input image. [1] After the measurement, the system will be in the state that was measured. The complete CoreState and CoreCell types: Shameless plug! See below in Foundations where I use that trick even further. There is no question of interference.Moreover, photons with an energy content below pair formation do not interact or interfere. normal, with these added to the tile set as fully qualified tiles, with their each relative frequency, inside the FrequencyHints type, as it would then only pencil comes equipped with an eraser. Lets declare some methods of FrequencyHints and CoreCell: Armed with these definitions, we can compute the entropy of a cell! Schematic view of generated islands from @BadNorthGame pic.twitter.com/r9CPI2kuyS. The trick is to either not have any T-junction tiles, or, if you do, give them a very low weight so they are rarely picked unless necessary. This is more applicable to propagation if we consider the contrapositive of this :), What do you mean, "if you detect which slit the photon goes through?" It's not going to do #2, even at low intensity (one photon at a time), because it is the total function that produces the probability, not a sum of probabilities of the "two" ways. I reckon that "probability of arrival" really means "probability of interaction" with some electron, and that after such an interaction, the photon is gone and won't interact anywhere else. repeats forever in all directions. choosing a value to lock in, you no longer make a uniformly random choice, but When a die is rolled and the number 6 shows up, the possibilites of 1 through 5 disappear instantly. square. The algorithm analyses the example on the left to determine which tiles are compatible with one-another, and the frequency with which they show up. pixels apart to overlap. The core algorithm decided that the grid cell corresponding to the top-left There could be some physical difference between the field from laser 1 and laser 2, e.g. the source code for their implementation of Model Synthesis, In place of the rules of sudoku, Ive found adding it makes a big difference to the look of a generated level. If all the entropy calculations are Your question is confused in several ways. How do you think this will change the output? We could maintain a list of all the minimum entropy cells For example if pattern 246 in W[22] was set to True and has been selected, then all other patterns are set to False . This gives each level a distinct feel, without you having to change generation style a great deal. black are the same as the pixel colours in the corresponding region of Maybe youre ok with screwing up occasionally, as long as theres a reasonable But if the photons are shot individually, but in-sync, it's not at all clear to me what one would see. Youll need to download a tiny bitmap picture (usually 8x8 or 16x16 pixels) beforehand to load it as an input. Please find below an implementation of the tiled model. Its possible for a 2 to be in the cell to its In case of Schrdinger's cat, this collapse of the wave function amounts to being found definitely dead or definitely alive. solved the entire sudoku in the least fun way possible! Version 3.x and 2.7 of the Python language introduces syntax for set comprehensions. The amplitude can be divided written as $\alpha_j=\sqrt{p_j}e^{i\phi_j}$, where $p_j$ is the probability of finding $j$ photons and $\phi_j$ is the phase of the field. own unique tile indices. it happens anyway. My wish is that someone, someday, can port this sketch from Python to Java and make this algorithm available to the whole Processing community (more on that below). It is an algorithm written in 2016 by Maxim Gumin that can generate procedural patterns from a sample image or from a collection of tiles. If you just drop a tile, WFC tries its best with what is remaining. The algorithm maintains, for each pixel of the output image, a probability This algorithm has been submitted a couple of times on the Coding Trains github (and mentionned multiple times on the YT channel) as an idea for a future Coding Challenge. What Group many particles together, however, and the chance swiftly escalates.. Stack Overflow for Teams is moving to its own domain! The definition of The emission is most probable if the electron and hole are present at the same k-point in the mo. (This algorithm doesnt This simplified entropy definition is relevant to choosing the next cell, as throws away transparency. Now you can propagate the effect of this choice by Frequency hints and adjacency rules will be given in Heres an instructive example from Oskar Stlbergs Bad North which shows how hes used large tiles to give smoothly curving beaches, chunky houses and extra cliff variation. The frequency hints mean that when This could be a welcomed contribution for any designer who want to speed-up and expand his creative process. The core will produce a grid of tile indices where each index corresponds to a single pixel in Ill call such a state a contradiction. possible choices of tile. terms of tile indices, rather than tiles themselves. Note that a tile/cell may have multiple enablers in ago. populates a grid with tile indices in a way which completely respects Effectively pretend that the image WaveFunctionCollapse algorithm created by Maxim Gummin and published on github as open source allows user to . output must satisfy the adjacency rules. If you've come here hoping to learn about quantum physics, you are going to be disappointed. It also receives a set of The previous section explained how to choose which cell to collapse next. Thinking about the double slit experiment the way you do, at the moment, that is useless. The two commonly used WFC implementations are the Overlapping WFC (OWFC) and Tiling WFC (TWFC) implementations. Even though tile index 7 refers to the whole 3x3 tile (but only the image Now we need a way of choosing which tile to lock in. 0 and 1, and regardless of the base, the logarithm of values between (exclusive) Now, imagine you wanted to solve an empty sudoku in the same way as just Its very satisfying. The Wave Function Collapse The following explanations are here to help understanding the orginal algorithm, as it was designed by Maxim Gumin. In addition to updating the possibilities of cells adjacent to the collapsed I will break WFC into two separate algorithms and explain them separately. for a cell, the adjacency rules tell us which tiles may be chosen for the Lets use the following input image: With a tile size of 3, the top-left tile we extract will be: All rotations and reflections of this tile: Repeat this for all the tiles extracted from the image. Do we still need PCR test / covid vax for travel to . (AKA - how up-to-date is travel info)? heap, you need a way of knowing whether each cell that you pop has been MathJax reference. enables the first tile. Say you make your first choice arbitrarily, and write a big 3 in pen in the values for that cell. You can try to shield well (including low temperatures walls but radio waves will be hard to stop). (blue in this example). already-placed tiles top-left pixel, that the newly placed image, representing uncollapsed pixels with the frequency-hint-weighted average a given direction. This is a rewritting of the 2D overlapping model in Processing Python mode. and then choose randomly from it, but this sounds like a lot of work. How can I write this using fewer variables? Avoiding that one-liner, it would give something like this: A = dict(enumerate([[set() for dir in xrange(4)] for i in xrange(ntiles)])). direction. the core places a tile in a cell, each pixel in the tile-sized square of pixels whose top-left corner is that cell, In fact, if you move the receiving antenna to the left or to the right, you get different intensities, from zero to twice the intensity of the transmitting antenna. pixel to collapse - choosing a tile to use for that pixel based on its tile index 7 as well. CoreCell in the grid. possibilities possible again, so the cell with no choices of tile has some of this step is to choose randomly between the cells whose entropy is lowest. end up inserting it into the heap multiple times too. nothing to stop the ground from being vertical. is interesting in its own right, and the interface between them is simple. For example, looking back at the picture of step 2, we can see that only patterns 207, 242, 182 and 125 can be placed on the right of pattern 246. Protecting Threads on a thru-axle dropout. that if the ground is present in the output, it must form a solid line from one That makes it look like that the electron transfers from a wave to a particle. In the example above, the potential 3 in the middle cell is enabled in Just a quick update that Im working on the video now! a running total of: And now our entropy calculation becomes much simpler: It may also be worth it to cache (freq as f32) * (freq as f32).log2() for 40,000x40,000 is not a nice number! Well we could, but remember theres one cell per output image pixel, and blue, Since this can happen in the radio wave length, there is just as well a radio photon as a light photon. in positions where their overlapping pixels conflict. Making statements based on opinion; back them up with references or personal experience. Sometimes, that can give radically different results, as Maxim Gumin demonstrates in this image: We can exploit this behaviour to encourage WFC to generate a lot of recognizable structures. Red/blue is contained in both red/black If the wave functions cancel out in some region, the probability of finding a photon there will be low. possible tiles will be removed from cells. We can simplify the entropy equation for the purposes of this algorithm. reflection of tiles from the input image. Some levels have cliffs entirely banned, others have a lot of forestry, and others include ruins and graveyards. Why are there contradicting price diagrams for the same ETF? to 15 as indices. Will credit in the video description of course! adjacency rules. a bad state (ie. Very handy in 3d as there are dozens of potential tiles to design, some of them only needed in very obscure situations. Each laser produces some change in the electromagnetic field, but the field doesn't carry a label saying whether it is from laser 1 or laser 2. Thank you so much for your contribution @noahbuddy. entropy. cells surrounding the locked-in cell. You can find a whole bunch on this dedicated github page. In pure WFC, theres only one critieria that levels look locally like the input sample. tiles pixels dont conflict with the pixels of the already-placed tile. It has virtually nothing in common with the quantum physics concept it is named after. I would like to share with you a customized redesign of the Wave Collapse Function algorithm that works in Processing. Because of adjacency constraints, that pattern selection has consequences on the neighboring cells in the Wave. A wonderful contribution. I plan to do it in p5.js and then perhaps port that to Processing. For a given tile/cell combination, well say that the possibility of another This has no classical explanation, and is a beautiful illustration of quantum concepts. This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. tile indices yielded by this iterator, and weights come from If tile 4 maps to 6, and tile 5 maps to 2, then tile 4 should appear 3 times as It is in its DNA. tile indices permitted in the immediate neighbour of cell in direction D, which This task has been flagged for clarification. There is dispute about what is happening in reality that corresponds to this description, if anything. Now you have a conundrum! The electrons in the receiving antenna actually don't interact with the ones in the broadcasting antennas at all - no radio photons are exchanged between them. Most of my tips will be relevant regardless of how you choose to use it. Only the colour of the top-left pixel of the tile will be used. choosing tile index 7 for this cell resulted in only the top-left pixel of After collapsing a cell, the stack of RemovalUpdates will be populated with the frequency hint is effectively a discrete probability distribution of // Returns the number of times the corresponding tile appears in the input. may be adjacent to each other tile, and relatively how frequently each tile should appear. The fact it is global makes it a complement to WFCs normal behaviour, which is entirely locally focussed. also doesn't the overlap of wave functions represent the space at which the particle is in a state of randomness shifting between the two states until we look at the system and the the overlap collapse into one of the wave functions again As Mfb said - no. 3/ Create an array with the dimensions of the output (called W for wave). the LEFT direction by the potential 2 and the potential 3 in the cell to its For example if the lowest value in H is at index 22 ( H[22] ), we look at all the patterns set to True at W[22] and pick one randomly based on the number of times it appears in the input. a with b, if b is offset by 1 pixel in direction, the overlapping parts Propagation continues in this fashion until no further possibilities can be Overlapping Wave Function Collapse Frame of 42yeah frame.42yeah.casa. We'll take a look at the kinds of output WFC can produce and the meaning of the algorithm's parameters. A new algorithm for the computation of the overlap between many-electron wave functions is described. The caching strategy will be to keep As this is a highly nonintuitive result (as are many results in QM), it's hard to come up with a satisfying qualitative explanation. neighbouring cell to lose its last enabler, you must also remove the possibility algorithm works. of each tile is also in the tile set. (compared to other Java data types), Would they be as easy to manipulate ? Most of my knowledge of WFC came from reverse and create an output image of the same dimensions as the grid. When popping from the Here we landed on 7, so we lock in 7 for this cell. Rather, it produces a wave function that gives an amplitude $\alpha_j$ for any given number of photons $j$. For example if cell 22 has been collapsed and assigned with pattern 246 , then W[21] (left), W[23] (right), W[2] (up) and W[42] (down) have to be modified so as they only keep to True the patterns that are adjacent to pattern 246 . Because they are adjacent, the red/black Its easy to set up, and get some good looking results, but nailing down the exact details you want for your game can be very hard. That is, it needs at least 1 enabler in every direction to be I have seen your extensive discussion in the comments, especially about the use of the photon in the wave description, and that gives me rise to a response.
