Name

glMatrixMode - specify which matrix is the current matrix

C Specification

void glMatrixMode(GLenum mode)

Parameters

mode

Specifies which matrix stack is the target for subsequent matrix operations. These values are accepted: GL_MODELVIEW, GL_PROJECTION, GL_TEXTURE, and GL_MATRIX_PALETTE_OES. The initial value is GL_MODELVIEW.

Description

glMatrixMode sets the current matrix mode. mode can assume one of these 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_MATRIX_PALETTE_OES

Enables the matrix palette stack extension, and applies subsequent matrix operations to the matrix palette stack.

Errors

GL_INVALID_ENUM is generated if mode is not an accepted value.
