# Method GL.glMatrixMode()

Method glMatrixMode

  `void glMatrixMode(int mode)`

Description

  glMatrixMode sets the current matrix mode. mode can assume one of three 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.

  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.

Parameter `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.

Throws

  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.
