But it is more efficient and customized compared to normal TOPs. In particular the errors that can cause a crash are out of bounds array access in either sampler arrays or uniform arrays. Since it’s a bit of a complex thing to work through, it’s split into several parts, so that you really understand what’s going on. The GLSL TOP can act as a pixel shader, or the more general and complex Compute Shader. Currently there’s just the transition type menu and a 0-1 progress slider (personally, I’m driving that using hand-keyed animation curves). TouchDesigner uses GLSL 3. Raymarching has been around for a long time, but it is very different from traditional rendering, and it requires a strong knowledge of GLSL and vector math. 30 and newer versions as it's language.

I just pushed up the first part to the GitHub repo, which is a section on how to create the foundation for a GLSL particle system using GLSL MAT and how to move the touchFluid is a lightweight 2d Semi-Lagrangian fluid solver for TouchDesigner. Rotation // Example Pixel Shader uniform float TouchDesigner. Refer to the Write a GLSL TOP article for more info on using A shader in TouchDesigner is the OpenGL (pre-2022) or Vulkan (2022-) GLSL code that runs on the GPU and creates rendered images from polygons, textures, CHOP channels and parameters. TouchDesigner's main supported version of GLSL is 4. 30 or later.
