GLMATRIXMODE(3G)

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. Three values are accepted: GL_MODELVIEW, GL_PROJECTION, and GL_TEXTURE. The initial value is GL_MODELVIEW. Additionally, if the 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
