- The best motion blurring I've seen for the Amiga was done with
- ImageMaster. It really does blur the area specified in the direction
- you specify. I've seen other ways of doing motion blurring on animation,
- one being in 'Animation Station' (under-rated), which I think works
- on the same principal as you described, where the previous 5 or so frames
- are added to the current frame at different intensities, sorta a
- 'stagger-strobe' effect. It worked pretty good on some old HAM animations
- of mine (not to mention that HAM indirectly helped with the fringing..).
-
- What would be a 'hack' way of doing it would be to be able to specify
- what polygons are able to 'blur' and have the renderer blur that
- polygons colour in the opposite direction that it is moving in.
- I don't know if this would actually work, or what kind of math is involved,
- just an idea...
-
- Actually just thinking back to your AC article, you could kinda do it
- with the 'transparency' setting in LightWave, like for rocket blasts.
