WebThe OpenGL ES Shading Language defines an assortment of built-in convenience functions for scalar and vector operations. Many of these built-in functions can be used in more than one type of shader, but some are intended to provide a direct mapping to hardware and so are available only for a specific type of shader.

I mean to … WebA sampler in GLSL is a uniform variable that represents an accessible texture. It cannot be set from within a program; it can only be set by the user of the program. Sampler types correspond to OpenGL texture types. Samplers are used with GLSL texture access functions. The process of using textures with program samplers involves 2 halves.
