glVertexBindingDivisor 3G
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`.
