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_ATTRIBUTES.
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_ATTRIBUTES.
