Re: Some clouds

With the direct lighting code slightly adjusted, the cloud looks a bit more like it's supposed to (the sun is to the right, fairly low, and slightly 'behind' the cloud). I think there's still some problems with the lighting, but need to look into it. http://personal.inet.fi/muoti/eimuoti/ray/cloud/c...

Re: Some clouds

Some tweaks to the cloud generator and the way the path tracer handles cloud masses. The cloud below is the condensation from about 0.7 billion air parcels moving through the fluid field, which is at a resolution of 200x200x200. http://personal.inet.fi/muoti/eimuoti/ray/cloud/cloud_8.png The black s...

Re: Some clouds

Thanks, zsolnai. If you've been thinking about doing it, just do! The video's pretty cool – since you already have a fast fluid simulator running on the GPU, you can just put in some air parcels (or particles if you will), calculate condensation from them (this should be very fast on the GPU) as the...
