GPU Particles

Thursday, February 28th, 2008

Check this out: 10,000 particles running on my new system (with no gfx card!) at a consistent 30fps, all with different velocities, distance blurring, etc.:

I had 65,000 running just fine, but it rendered as a big white blob, which didn’t look very presentable. I’ll cover the techniques behind this sample soon, along with providing full source. Most of this is actually done on the (motherboard-embedded) gpu though – I was surprised it ran well at all!

So stay tuned – I’ve got a couple graphics samples in the works that I’m hoping to start filling my website with soon. I’ll release this one once I clean up the presentation a little (it’s not quite what I want – yet). I’m hoping to make it a screensaver similar to Hawk’s recent flash sample entitled Life. Anyone see the irony?

Video of my cloud

Monday, February 5th, 2007

I thought a video might be a little better for demonstrating my cloud.

Granted, it’s not the best quality, but it still shows what’s going on. You can see that the cloud maintains its shape as you move around and even through it. You can also see the subtle animation.
