Name

glVertexBindingDivisor — modify the rate at which generic vertex attributes advance

C Specification

`void glVertexBindingDivisor(`	GLuint `bindingindex`,
	GLuint `divisor)`;

Parameters

bindingindex: The index of the binding whose divisor to modify.
divisor: The new value for the instance step rate to apply.

Description

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.

Errors

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.

Associated Gets

glGet with arguments GL_MAX_VERTEX_ATTRIB_BINDINGS, GL_VERTEX_BINDING_DIVISOR.
