## Name

glMatrixMode — specify which matrix is the current matrix

## C Specification

`void `glMatrixMode`` | `(` | `GLenum `mode`);`

## Python Specification

``glMatrixMode`` | `(` | ``mode`) → `None``

## Parameters

`mode`
  Specifies which matrix stack is the target for subsequent matrix operations. Three values are accepted: `GL_MODELVIEW`, `GL_PROJECTION`, and `GL_TEXTURE`. The initial value is `GL_MODELVIEW`. Additionally, if the `GL_ARB_imaging` extension is supported, `GL_COLOR` is also accepted.

## Description

`glMatrixMode` sets the current matrix mode. `mode` can assume one of four values:

`GL_MODELVIEW`
  Applies subsequent matrix operations to the modelview matrix stack.
`GL_PROJECTION`
  Applies subsequent matrix operations to the projection matrix stack.
`GL_TEXTURE`
  Applies subsequent matrix operations to the texture matrix stack.
`GL_COLOR`
  Applies subsequent matrix operations to the color matrix stack.

To find out which matrix stack is currently the target of all matrix operations, call `glGet` with argument `GL_MATRIX_MODE`. The initial value is `GL_MODELVIEW`.

## Errors

`GL_INVALID_ENUM` is generated if `mode` is not an accepted value.

`GL_INVALID_OPERATION` is generated if `glMatrixMode` is executed between the execution of `glBegin` and the corresponding execution of `glEnd`.

## Associated Gets

`glGet` with argument `GL_MATRIX_MODE`
