glMatrixMode - specify which matrix is the current matrix
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 default value is GL_MODELVIEW.
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.
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.
