Hi James:
hey ya'll,
...motion blurring is a very high priority for me atm :-) Unfortunately, there isn't exactly an easy way :-\ The traditional way is to cheat and use the accumulation buffer: ya render to this buffer several frames with each slightly lighter, then pop out the result...this doesn't give a directional blur, tho, and also it so happens that OSX has a software implementation of this buffer, so it's sloow...
Ummm, sound a bit out of my depth;) but sufficient to say that its not easy...
...the better way is still in the future, and involves vertex &/or fragment programs along with pBuffers...there's plenty about this on the web, but it's just not do-able in GEM atm...soon, perhaps?
Not do-able in Gem at the moment? Is it because of the way Gem is written or OpenGL?
Cheers
CHUN
