Hi Jeongsoeok,
The CoordinateFrame relates the standard OpenGL coordinate frames - the options:
enum CoordinateFrame
{
WINDOW,
PROJECTION,
VIEW,
MODEL
};
Which mean
WINDOW - the coordinates of your window,
PROJECTION - the non dimensional clip coordinates before
projection matrices has been applied,
VIEW - eye coordinates after the projection matrix has been
applied, but before the view matrix has been
MODEL - model/world coordinates, after the view matrix has been applied.
