Hi there:
I would like to draw the trail of a geo in motion, how can I do this? I am thinking of delay the gemlist to the specified amount but having no luck in doing so.
I think that it is not as easy as one might hope (but I look foward to a discussion on the subject).
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...
...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?
