3-D Texturing

3-D Texturing is a hardware accelerated technique for volume rendering, which makes it relatively fast. This is because it uses the graphics hardware. Like Splatting, 3-D Texturing takes the 3-D scalar data and maps it onto a rectilinear grid. This grid is then mapped to a 3-D texture. The 3-D texture is then loaded onto the graphics card into the texture memory. The method then draws a set of planes. These planes are perpendicular to the view of the user, and are stacked from the back to the front. The texture is mapped onto these planes. The resulting image quality is much better than by using the splatting method.
