GLSL has five basic data types:

• float
• int
• uint
• bool
• sampler (used for sampling textures)

Vector types for float, int, uint, and bool:

• vec2, vec3, vec4:  2D, 3D and 4D floating point vector
• ivec2, ivec3, ivec4:  2D, 3D and 4D integer vector
• bvec2, bvec3, bvec4:  2D, 3D and 4D boolean vector

Matrix types for float:

• mat2, mat3, mat4: 2x2, 3x3, 4x4 floating point matrix

Sampler types:

• sampler1D, sampler2D, sampler3D:  for 1D, 2D, 3D textures
• samplerCube:  for cube map textures
• others…

Operator overloading for matrices, vectors as expected.

Vector and matrix types compatible with GLM!
