TSL: add support for interpolation type qualifiers such as centroid #30576
Description
Description
It appears it's not currently possible to create a varying with TSL with a interpolation type qualifier, for example in GLSL, centroid.
centroid varying vec2 uvCentroid
In three.js WebGLRenderer projects I have used centroid to work around issues with texture bleeding when using texture atlases with MSAA.
Solution
Consider exposing common interpolation qualifiers via TSL.
I don't have good concrete API suggestions, but here's a simple example of how I'd use this:
const uvCentroid = uv().interpolation("centroid")
const color = texture(map, uvCentroid)
Alternatives
Some other general API for exposing common qualifiers.
