- All versions of Playmation (and all release versions of the older
- Journeyman) require a math chip, which most 3D animation people already
- have. For the record, way back when I had a non-math chip version
- for my Amiga 2000 that I was helping to test (when it was in early
- Alpha, this was during 1989). Believe me, you want it to use the
- math chip. Playmation will run on the following: Amiga 2500,3000 and
- above with mathchip, PC 386/486 with mathchip, and MacII and Quadras
- with mathchip.
-
- One of the reasons some people say that the renderer runs slow has more
- to do with what they test it with. We keep seeing people raytrace a
- scene with all objects reflecting with shadows in Playmation and compare
- it to a simple polygon scene without reflects and shadows on a scanline
- renderer, and declare Playmation is slow. It's all relative. Luckily
- for everyone, 486's keep dropping in price, and they make great render
- engines, and all our objects are portable between platforms. There will
- also be support for the YARC board on Mac Render24. I'll leave you with
- the following quote.
-
- "The creators of Playmation chose to use raytracing. Obviously, the price
- paid for this decision is speed. Still, Playmation represents one of the
- fastest PC-based raytracers I have seen." - Computer Graphics World, Jan '93
