Also I have a problem with Mathematica. I need to revolve a tree dimensional object, produced by the GarnetSurfaces package (Ross Moore-Dept of Mathematics, Macquari University North Ryde Australia around a certain axes. I solve the problem by calculating the vector coordinates of every new ViewPoint, but there is a problem when I rotate the object around horizontal axes. Half of produced images ar the mirrored images of the other half, so that I can see only the "front face" of the object and not the back face. I think the solution is to fix every time the "up" of the systhem. This seams to be a problem that has to be solved currently in any 3D animation, but for me is the first time that I am confronted with it. So, can some one help me? Is there in the Mathematica Package a certain function or atribut that specifies the "up"? Thank you, frank schobel ......
