I am currently trying to implement a Lattice-Boltzmann Implementation of fluid simulation in threeJS. This requires each point in the grid to hold 9 values representing distribution functions for the fluid. Since all of this information cannot be stored in a single texture, I was trying to use three…

You have to use GLSL30 and restructure your shader a bit. Here’s some untested code from gpt as an example: <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <title>Three.js Multi-RenderTarget Example</title> <style> body { margin:0; overflow:hidden; } </style> </head> <body> <scrip…

Hey. The code you provided uses WebGLMultipleRenderTargets which is a deprecated function. There is no longer any documentation regarding it. In the WebGLRenderTarget documentation( WebGLRenderTarget – three.js docs ), it talks about a count parameter to define the number of render targets but I’ve…

I have I think. [image] Reflective shadow maps Showcase I’m playing with some features that I’ve missed out on because I haven’t worked with three much lately. I wanted to use MRT and revisit an old paper that I never got around to implementing properly. I don’t think I’ve…

I would do calculations in a compute shader. A compute shader can store multiple textures. Here is one of my compute shaders as an example: Spiri0/Threejs-WebGPU-IFFT-Ocean-V2/blob/5a3c0f8c78fc16c111c7ab887908f8cb24c11547/resources/shader/IFFT/timeSpectrum.js import {wgslFn} from "t…
