Hi Vijay, VisAD is designed to let you extend its classes to do things like add your own Java3D code. However, volume rendering is a bit complex, since it manages six different sets of texture planes and switches among them as the user rotates the view in 3-D. In order to use VisAD's volume rendering, it will be MUCH simpler to put your data into VisAD Data classes, as described in section 4.11 of Ugo's VisAD Tutorial.
