WebApr 16, 2024 · In GLSL, the types vec2, vec3, and vec4 represent 2D, 3D, and 4D floating-point vectors. (There are also types for integer and boolean vectors, which are not discussed here.) Vector variables are defined as you would expect if C, C++ or Java had these types: The data types for floating-point 2×2, 3×3, and 4×4 matrices are: mat2, mat3, and mat4 : WebDec 11, 2024 · GLSL. A sampler is a set of GLSL variable types. Variables of one of the sampler types must be uniforms or as function parameters. Each sampler in a program represents a single texture of a particular texture type. The type of the sampler corresponds to the type of the texture that can be used by that sampler.
