Adventures in Screen Space

Eight years ago, just when I first started writing this blog my second post was about screen space ambient occlusion. I used that renderer for all my physics experiments, leading up to the fluid simulation that became Sprinkle. At that point I left desktop computing in favor of mobile devices. Ten games later I'm now back to desktop machines and I'm completely blown away by all the computing power.

For the first Sprinkle game I had to make dedicated geometry with holes in it when drawing large alpha blended overlays because the fill rate was so terrible. Now I'm running hundreds of lines of code really doing complex computations per pixel. Sorry, you have probably already adjusted but this will take me a while.

So what would be more fitting than to freshen up that old physics renderer (well more like starting from scratch, but still). I have been wanting to experiment with physics in VR for a while and now is the time. For this I need a renderer that can handle a truly dy…
