glVertexBindingDivisor - OpenGL ES 3.1 Reference Pages

## 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`.
