- Hi Stephen...
-
- I'll try something large and quantitative - but I rendered a well-bounded
- subject in PoV consisting of over 100,000 smooth_triangles (10Mb input file)
- at a respectable size, with anti-aliasing and it traced surprisingly
- quickly. There were several layers of alpha textures, multiple reflective
- ripples, a large height field and an image_map.
-
- This PoV source (westsol2.zip 658k - unzips to 2.5Mb) is available from:
-
- ftp.informatik.uni-oldenburg.de (134.106.1.9)
- pub/dkbtrace/incoming (at the moment, will be moved into a dir soon)
-
- It is a lofted classic yacht I produced from the plans and dropped in a
- created scene, about three days work.
-
- This seems to be an emerging site for POV files,
- Check out pub/dkbtrace/scenes or incoming too.
-
- Vivid can certainly create more lifelike surfaces, but using it to render
- several thousand triangles was slower than the equivalent PoV - is there any
- room for improvement on the bounding allocation algorithm?
-
- Do keep up the good work Stephen, Vivid is still one of my favourites.
- (I've worked out a way of creating 3d Adobe fonts for vivid and pov -
- mostly by using complex Word 4 Windows macros(!) - the results look good.)
-
- Cheers
- Andy.
