I’ve been learning about the shader in threejs recently. In the ShaderChunk folder, some files have a _pars_
tag in their file names. I want to know why to use _pars_
for marking and the full name of the tag.
-
fog_fragment
is for the calculations insidemain(){}
-
fog_pars_fragment
are the parameters that need to be declared at the beginning of the shader, like uniforms, varyings, #define statements, etc.
