glMatrixMode

glMatrixMode
glMatrixMode: specify which matrix is the current matrix.
C Specification
void glMatrixMode(
Parameters
mode
Description
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.
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.

GLenum 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.
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.
