- There is a new version of the RTrace ray-tracing package (8.0.0) at
- asterix.inescn.pt [192.35.246.17] in directory pub/RTrace
-
- ****************************************
-
- The MAC port is being prepared to be released by Reid Judd
- (reid.judd@east.sun.com) and Greg Ferrar
- (gregt@function.mps.ohio-state.edu).
- A working version will be available shortly!
-
- ****************************************
-
- Enhancements were done since version 7.3.2, mainly:
-
- 1. It has no limit on the number of objects to render (there is a
- command line option to control it; scenes with up to 1000000 have been
- rendered!).
- The same applies to light sources and surfaces.
-
- 2. It is now possible to produce animation fly-throughs easily. The scene is
- read only once and successive images are produced. There are new command
- line options to specify it. The fly-throughs may be controlled by the
- EYE and LOOK points, the UP vector and the APERTURE angles.
- All there is to do is just create a text file with the numbers and give
- it to the program...
-
-
- The support programs 'nff2sff', 'nffclean' and 'nffp2pp' have been
- enhanced to support unlimited number of objects, etc.
-
-
