some quick and diry sparks/explosion test

just passed some PFlow to Krakatoa… Some glow added in post & info overlay…turned out to be some nice supernova/explosion sequence after all. still hours of work ahead ´til that looks cool but here´s a preview:

(i used the sorensen 3 codec, about 10mb)



kind regards

Lookin’ great, push it!

nice!



so… I’m still new to Krakatoa… but there’s not ways to specify sizes per particle, right?



and no rolling particles… ?



just want to make sure, thanks

No particle size per se. Krakatoa is a point renderer, so it computes the

color of a pixel based on the volume of particles within that area. You can

increase the density, so that it takes fewer particles to fill an area, but

there is no way to actually specify particle size.



Particles are in fact spinning as you specify in your particle system, but

the point renderer has no way to show them rolling.

At least not yet. We plan to enable normals from particle orientation as an option, so spinning particles would shade as if they were small planes with a normal vector, shading brightly when facing the light source and turning black when facing away. So spinning particles would blink like pulsars ;o)

Right now, this shading mode is supported for geometry vertices only.
