Attrib parameters are per-vertex attributes such as vertex normals. Local parameters are applied across a program's entire data set for a given shader pass. Env parameters are applied across all programs. ARB Variables. All ARB assembly variables are float4 vectors, which may be addressed by xyzw or rgba suffixes.

WebSince OpenGL is designed for rendering, it is natual that it provides extensive vector support. Both geometry (XYZW) and color (RGBA) require vec4, and it is easy to perform operations on vectors (e.g. addition, subtraction, dot product, …).
