glEnableVertexAttribArray 3G
glEnableVertexAttribArray glEnableVertexAttribArray glDisableVertexAttribArray enable or disable a generic vertex attribute array

## C Specification

void `glEnableVertexAttribArray` GLuint index void `glDisableVertexAttribArray` GLuint index

## Parameters

index

  Specifies the index of the generic vertex attribute to be enabled or disabled.

## Description

`glEnableVertexAttribArray` enables the generic vertex attribute array specified by index. `glDisableVertexAttribArray` disables the generic vertex attribute array specified by index. By default, all client-side capabilities are disabled, including all generic vertex attribute arrays. If enabled, the values in the generic vertex attribute array will be accessed and used for rendering when calls are made to vertex array commands such as glDrawArrays or glDrawElements.

## Errors

`GL_INVALID_VALUE` is generated if index is greater than or equal to `GL_MAX_VERTEX_ATTRIBS`.

## Associated Gets

glGet with argument `GL_MAX_VERTEX_ATTRIBS`

glGetVertexAttrib with arguments index and `GL_VERTEX_ATTRIB_ARRAY_ENABLED`

glGetVertexAttribPointerv with arguments index and `GL_VERTEX_ATTRIB_ARRAY_POINTER`
