As a followup to my previous posting regarding the CSA 68020/68881 system I was able to time some scenes from Sculpt 3D with and without 68881 support. These timings are done with an Amiga 1000, CSA 68020/68881, 1MB 32bit ram, and 6MB 16 bit ram. 3D refers to the regular distribution of Sculpt 3D and 3D8 refers to the version offered that utlizes the 68020/68881. Scene 3D 3D8 Apple 00:28 00:14 Boing 00:30 00:15 Rocker 39:30 12:36 This may or may not constitute considerable improvement for some. I should know better than use such a relative term. When I first received the package I tried the rocker and I knew that the 3D8 package was faster. I hope the timings help. In terms of the library support for the 68881 under 1.2 I was basing my comments on my own observations. The system as received from CSA did not mention a replacement library for 68881 support. One example that was sent was a Basic program with some hand code implemented. I am using the Absoft Turbo Fortran which does support the 68020/68881.

The last time tried to do the rocker on a stock amiga, rendering time was like 15 hours. Your time for rocker falls into my prediction for floating point acceleration. My upgrade of Sculpt3d claimed 300% improvement over the previous package. Looks like your improvement for the versions you have. Settings for rendering make a big difference in rendering times. I guess I'll have to try again, although I don't like tying my Amiga up to do this. Anybody else tried rendering rocker? This is really strange. > Bob Flocchini > University of California , Davis > flocchini @ deneb.ucdavis.edu -- Work: Computer Consoles Inc.
