glVertexAttrib4findex
glVertexAttrib4findex is a function in the OpenGL programming interface used to specify the value of a generic vertex attribute. This function is part of the OpenGL Shading Language (GLSL) integration with the fixed-function pipeline or when working with programmable shaders. The function allows developers to set a single floating-point vertex attribute with four components.
The parameters for glVertexAttrib4findex are an index and four floating-point values. The index identifies which generic
This function is typically used to provide per-vertex data that is not part of the standard vertex
