gluProject - map object coordinates to window coordinates
int gluProject( GLdouble objx, GLdouble objy, GLdouble objz, const GLdouble modelMatrix[16], const GLdouble projMatrix[16], const GLint viewport[4], GLdouble *winx, GLdouble *winy, GLdouble *winz )
objx, objy, objz Specify the object coordinates. modelMatrix Specifies the current modelview matrix (as from a glGetDoublev call). projMatrix Specifies the current projection matrix (as from a glGetDoublev call). viewport Specifies the current viewport (as from a glGetIntegerv call). winx, winy, winz Return the computed window coordinates.
gluProject transforms the specified object coordinates into window coordinates using modelMatrix, projMatrix, and viewport. The result is stored in winx, winy, and winz. A return value of GL_TRUE indicates success, and GL_FALSE indicates failure.
