GLMATRIXMODE(3G)														  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 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
