#WavefunctionCollapse

I've been experimenting with adding simple backjumping to DeBroglie, my #wavefunctioncollapse library. Backjumping reverts multiple steps at once, which means the solver is less frequently stuck in tricky or unsolvable states. It should enable larger, harder generations to run.

The #WaveFunctionCollapse algorithm has been introduced by @ExUtumno as a texture synthesis method and nicely used by @OskSta for procedural generation of 3D buildings. Wait, what, how do those relate? Sounds like totaly different applications! ⬇️ Answers in the thread! 1/18

I just uploaded my #procjam project! An infinite city, procedurally generated with the #wavefunctioncollapse algorithm, now with procedural trees. #procgen Download the game here:

Prepared the landscape generator so it's ready for web demo release later today. Also going to drop some new moose boss combat footage of the Necromancer game. (it's at 20+ scenes now 🔥) #gamedev #WaveFunctionCollapse #threejs

To reveal the building hidden in the wave function, I implemented a wave function collapse algorithm entirely in geometry nodes😆 The convergence is really slow, maybe something isn't working correctly... #b3d #geometrynodes #wavefunctioncollapse

#WaveFunctionCollapse texture synthesis on #fpga. Algorithm is hard-coded into hardware with Silice, and is specialized to the tile set. Goal is to search for solutions extremely quickly by exploiting the #fpga architecture. Yes, this is hardware #procgen! (1/n)

The #WaveFunctionCollapse algorithm by @ExUtumno has got really trendy in #ProcGen and game dev communities, but it wasn't the first of its kind! It was highly based on Paul Merrell's work published almost 10 years earlier.⬇️ 1/7

I've never actually explained about DeBroglie/Tessera's path constraint, despite it being the most useful feature I've written. Basically, it's an enhancement for #wavefunctioncollapse procedural generation that can for the generation to be globally connected.🧵

Question about #wavefunctioncollapse; if you generate a new world based on an existing world. How do you sample the weights for each tile? If I have a simple 2d world with roads and use the frequency of each tile as weights I get too much road. @boris_brave or @OskSta ?

Ok, I think I've finally figured out @OskSta's "editable" wave function collapse ( Here's a very bare bones prototype which doesn't really show off how powerful it is. But you can see how it sometimes changes multiple tiles at once. #wavefunctioncollapse

Added some flags. Gotta make it homely and welcoming.

Added 3D to my impl. of #WaveFunctionCollapse on a sphere in #GodotEngine. WFC visualised by transparent cubes. Very slow, need to convert the GDScript code to GDNative. Also want to attempt voxel normals to fix ugly seams. #procedural #gamedev #indiedev #screenshotsaturday

I made a generator of modern houses! #WaveFunctionCollapse #procgen #MagicaVoxel

Happy to report that the staircases finally know whether they're coming or going. #wavefunctioncollapse #Houdini

I finally finished my (first) #devlog on my switch from using #voxels to using #wavefunctioncollapse for #proceduralgeneration in #Unity. It was a lot of work, but I learned a lot too. Check it out. #MadeWithUnity #Unity3D #IndieDev #IndieGameDev #SoloDev

Taking inspiration from earlier #wavefunctioncollapse test module sets used by @OskSta, I present to you: maze like piping! +JapanTime #screenshotsaturday

I've made a "parity" constraint for #wavefunctioncollapse that improves its ability to resolve branchless paths. It basically works by finding enclosed regions, and counting if there are an even or odd number of exits. Coming to Tessera next version.
