glVertexBindingDivisor

modify the rate at which generic vertex attributes advance

void glVertexBindingDivisor(GLuint bindingindex, GLuint divisor);

bindingindex

The index of the binding whose divisor to modify.

divisor

The new value for the instance step rate to apply.

glVertexBindingDivisor, modifies the rate at which generic vertex attributes advance when rendering multiple instances of primitives in a single draw command. If divisor is zero, the attributes using the buffer bound to bindingindex advance once per vertex. If divisor is non-zero, the attributes advance once per divisor instances of the set(s) of vertices being rendered. An attribute is referred to as instanced if the corresponding divisor value is non-zero.

GL_INVAILD_VALUE is generated if bindingindex is greater than or equal to the value of GL_MAX_VERTEX_ATTRIB_BINDINGS.

GL_INVALID_OPERATION is generated if no vertex array object is bound.

glGet() with arguments GL_MAX_VERTEX_ATTRIB_BINDINGS, GL_VERTEX_BINDING_DIVISOR.
