....direction vector of the incoming ray) and is the surface normal vector then the line of sight after refraction is (3. 2) is the relative IOR computed as the ratio of the IOR of the exiting medium ( and the IOR of the entering medium ( Rodgman and Chen [RC01] show how refraction can be implemented in direct volume rendering. An object s IOR is modelled as a scalar field , which can therefore be defined either homogeneously over space (if for all and some constant , as it would be in surface graphics) or otherwise. A ....
....discussed earlier. Any of the proposed methods (of course, substituting the reflection vector for the view vector, can be used to resolve the problem. In Section 3.5. 2 we discussed the principles of refraction and reviewed Rodgman and Chen s work on adapting refraction to the volume domain [RC01] Here, we briefly supplement this by describing 9.5 Voxel Evaluation 224 how refraction can be implemented in a discrete ray tracing engine supporting the vlib API. If the API function calls specify that a volume object should refract light (i.e. if the VL REFRACT toggle option is set when a ....

The object is made invisible only to the primary rays and therefore still casts a shadow and appears in inter object reflections. reflect the background color.
