Comments
By default:
· The camera is positioned at the origin, looking down the negative Z axis (into the screen).
· The "Look Up" vector is the positive Y axis of the world space.
· The projection model is rwPERSPECTIVE.
· The viewport has a position of (0, 0) and a size of 0 by 0.
· The view window is centered about the origin of the camera space and has a size of CREAL(1.0) by CREAL(1.0).
· The view offset is (CREAL(0.0), CREAL(0.0)).
· The near (front) clipping plane is approximately CREAL(0.05) world space units from the camera.
· The far (back) clipping plane distance, in world space units from the camera, is a large value which depends on the numeric type of the library.
· The camera background color is black, i.e., [CREAL(0.0), CREAL(0.0), CREAL(0.0)].
· The backdrop raster is NULL.
· The backdrop offset is (0, 0).
