csmooth in geomview
I use the new version of the 4dviewer using csmooth shading to look at some of my examples. My question does not really involve the 4dviewer. For example, dump.75.4off as is found in /work1/roseman/May93. This shading is based on the "w-coordinate". I rotate the object in geomview--not changing the projection--just using the "r" mode of geomview. I should not expect to see the color of a point change, am I correct? (The color of a vertex is determined by the fourth coordinate.) But it does. One can see this most easily by turning the edges on so that one can more easily track a given point and also make sure it is not being occluded. What seems to happen is that the color one sees at a given point depends on the obliquness of the angle of the surface with respect to the camera position. (This is most notable for extreem angles) Why is this? Is this expected behavior? (It is not expected from the algorithm, since the rotations do not change the "w-coordinate" of a point.) If this is not expected behavior of cshading, is the problem due to software or hardware?
