In this paper, we present the development of a highspeed volume rendering system that combines 3D texture compression and parallel programming techniques for rendering multiple high-resolution 3D images obtained with medical or industrial CT. The 3D texture compression algorithm (DXT5) provides extremely high efficiency since it reduces the memory consumption to 1/4 of the original without having a negative impact on the image quality or display speed. By using this approach, it is possible to use personal computers with generalpurpose graphics capabilities to display high-resolution 3D images or groups of multiple 3D images obtained with medical or industrial CT in real time.
