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

Function Definition

 void glVertexAttribDivisor(GLuint index​, GLuint divisor​);
Specify the index of the generic vertex attribute.
Specify the number of instances that will pass between updates of the generic attribute at slot index​.


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.


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


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

GL_INVALID_OPERATION is generated if no vertex array object is bound.
