void glMatrixMode( GLenum mode )

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.

 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.

 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.

 glGet with argument  GL_MATRIX_MODE
