# glVertexBindingDivisor

## 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_INVALID_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.
