What is the 2D warp step and what types of commands are given to the conventional 3D graphics card?
Although VolumePro® supports the viewing of a volume data sets from any angle, it actually renders volumes to a base plane image. This base plane is parallel to and aligned with one of the faces of the rectangular volume data set. The resulting base plane image is distorted and not necessarily scaled to the screen or window size. To remove the distortion and fit the final image to the viewers display screen, a post-processing step called a 2D warp is applied. This step is a common operation in three-dimensional graphics systems and is typically done on the companion 3D polygon graphics board.
