4 days ago I've posted that I've made a compaire image showing the two possible alternatives for surface tesselations for the 1-8sphe.dat primitive. I've waited a while before giving my own opinion, but here it is: For me, the proposed alternative (...) (24 years ago, 3-Oct-00, to lugnet.cad)

I agree with Manfred's conclusions. I'd also like to add that if Travis had made his submission at a different time, so we didn't have the alternative, I would have been very happy to accept his version of the primitive. Another thought: what about (...) (24 years ago, 3-Oct-00, to lugnet.cad)

(...) Travis, what do you think about this: (please take a look at the following image) (URL) tesselation matches the existing normal 1-8sphe.dat tesselation closely, all "even" points are identical to the points in the normal 1-8sphe primitive. (...) (24 years ago, 4-Oct-00, to lugnet.cad)
