We have currently implemented our system on three platforms. All of the images in our paper were generated on the SGI Octane2, and all of the images in this presentation were generated on either the nVidia GeForce 3, or ATI Radeon 8000 series graphics cards. An important note here is that the interface we have presented, meaning the widgets and interaction modalities, are not dependent on the graphics systems, and can be implemented on a variety of different platforms.
