Material Color

Recommended Posts

Hi all,

I want to ask about StandartMaterial, if I add to material a ambientColor or a diffuseColor or a specularColor it means that this colors mix with material.texture colors in every frame, or just at once and then new colors saves somewhere in buffer.

Need to know this for performance, if all colors mixes every frame I think this bad for performance and I will be find some other ways.

Thanks : )

hi @negrant

all material in webgl is a shader and shader have 2 part vertex shader and fragment shader

in each frame vertex shader run for all vertex in the mesh ( if mesh linked to material ) and fragment shader  run per any pixel mesh looked in resolation

so that color mix by texture in all pixel 

all happen in GPU and GPU designed for do that it is optimized  too
