Given the intrinsic camera parameters returns the GL_PROJECTION matrix for opengl. PLease NOTE that when using OpenGL, it is assumed no camera distorsion! So, if it is not true, you should have undistor image

Parameters

orgImgSize	size of the original image
size	of the image/window where to render (can be different from the real camera image). Please not that it must be related to CamMatrix
proj_matrix	output projection matrix to give to opengl
gnear,gfar	visible rendering range
invert	indicates if the output projection matrix has to yield a horizontally inverted image because image data has not been stored in the order of glDrawPixels: bottom-to-top.
