PLEASE, someone with a Toaster out there answer this:
I was just looking through my pile of info on different graphics
software/hardware/workstations/etc., and came across the insert
in the Toaster brochure on its software. Something caught my
eye in the list of LightWave features.
"Particle systems with variable motion blur"
Have any of you played with this feature???? And if so, how
were your results? How about render times?
TIA
Sean

I have not played with the motion blur feature much, but basically, it will blur all single point 'polygons' based on the points movement between frames. The blur is adjustable by percentage. It seems functional and I have seen a fantastic image by Allen Hastings (Lightwave author) using the motion blur.... -Mike Powell-

I have not done anything with it yet, but what I know about it is that Lightwave only performs motion blur on single point polygons, ie. particles. This feature has some sort of intended future purpose but as of yet, the software does not exploit it. In the mean time, if you have an object defined by gazillions of 'particles', you can fling them about at high speeds and watch them blur...oooooohhh! I'll play around with it tonite, but I'm not expecting much. +--------------------------------------------------------------------------+ | Mark Thompson | | mark@westford.ccur.com | | ...!{decvax,uunet}!masscomp!mark Designing high performance graphics | | (508)392-2480 engines today for a better tomorrow. | +------------------------------------------------------------------------- +

As for the results, you may have already seen some of the early tests. For example, on the AmigaWorld animation tape there is a film called "March 1989 Demo Reel" which contains a scene of a Voyager spacecraft flying toward a gas giant planet with some moons. If you watch the stars, you'll see them blur properly as the camera pans (I set the camera shutter time to be half the frame time). Another example is the explosion of the NewTek logo in the Penn & Teller video, in which it gets blasted into 2001 sparks that leave trails and fade out. In the future I plan to simulate rain and fountains with LightWave's particles, as well as do more fireworks. - Allen Hastings
