GLSL functions I reuse frequently

yarn add glsl-functions

Functions to be imported separately and included in 'parent' glsl via #include statement. I use vite and vite-plugin-glsl, otherwise look into implementing the ARB_shading_language_include extension for your usecase. Or import and concatenate strings when passing in a shader string (Not tested yet).

• fragment/luminance.glsl

• utility/remap.glsl

• utility/safeSign.glsl
