NAME

       glVertexAttribDivisor - modify the rate at which generic vertex attributes advance during instanced
       rendering

C SPECIFICATION

       void glVertexAttribDivisor(GLuint index, GLuint divisor);

PARAMETERS

       index
           Specify the index of the generic vertex attribute.

       divisor
           Specify the number of instances that will pass between updates of the generic attribute at slot
           index.

DESCRIPTION

       glVertexAttribDivisor modifies the rate at which generic vertex attributes advance when rendering
       multiple instances of primitives in a single draw call. If divisor is zero, the attribute at slot index
       advances once per vertex. If divisor is non-zero, the attribute advances once per divisor instances of
       the set(s) of vertices being rendered. An attribute is referred to as instanced if its
       GL_VERTEX_ATTRIB_ARRAY_DIVISOR value is non-zero.

       index must be less than the value of GL_MAX_VERTEX_ATTRIBS.

NOTES

       glVertexAttribDivisor is available only if the GL version is 3.3 or higher.

ERRORS

       GL_INVALID_VALUE is generated if index is greater than or equal to the value of GL_MAX_VERTEX_ATTRIBS.
