Builds are slow and broken in TD 2022 versions

This should be helped by a TouchDesigner fix for a regression in spirv-tools compiling shaders: https://forum.derivative.ca/t/2022-26590-long-freeze-when-loading-raytk-scene/277745/ It should also be helped by #939

Export of SOP geometry from a RayTK scene

Yeah Houdini can do it. To export the points, you'd use a pointMapRender to sample the SDF at points in a grid, then use the resulting distance values to delete...

Issues wtih sampledPointMat with render2D

A lot of it seems to be based on how render2d handles materials, only using them within the bounds of the shape

2D SDF from image

Possible implementation using jump floodfill: https://www.shadertoy.com/view/4syGWK

S-Curve function

This is sort of achievable using bandField/stepField with interpolation functions

Support vec4 for object id output buffer

This will be challenging since the object id output currently produces a vector with two object ids and a blend factor.

Value matching operator

bandField kinda does this

PBR material not applying textures

This is a good starting point: https://youtu.be/Uo2wC-v7TUI I'll have a more detailed response later

RayTK as standalone or webGL possible?

Thanks for reaching out! The most feasible approach would be shader export. I started work on that a while back (see #14) but shifted focus to other areas. It would...

RayTK as standalone or webGL possible?

There are some other web-based tools that could work as an alternative. * https://github.com/stasilo/retrace.gl * https://github.com/charlieroberts/marching * https://cables.gl/
