( I am also pulling 0.5 Tb of texture and millions of poly so it is slow :p )Harry Bardakhttps://www.blogger.com/profile/13695864455424570291noreply@blogger.comtag:blogger.com,1999:blog-7277449027963623452.post-49179167725230093972012-02-26T01:02:56.263-08:002012-02-26T01:02:56.263-08:00I don't see why it wouldn't be possible to...I don't see why it wouldn't be possible to add SSS at some point.<br /><br />Yes, I know a bit of C++.Sam Laperehttps://www.blogger.com/profile/05688552048697970050noreply@blogger.comtag:blogger.com,1999:blog-7277449027963623452.post-80253444687926060772012-02-25T18:18:21.898-08:002012-02-25T18:18:21.898-08:00Would it be possible to add sub surface scattering...Would it be possible to add sub surface scattering to Brigade?

You can see in the screenshot that reflections are 8 levels deep and the diffuse character and glossy ball remain correctly lit up to the 7th level. The glass horse becomes darker and less transparent with each level of reflection, because refractive objects need at least 3 bounces to become transparent.<br /><br />Anonymous, all the noise issues will be taken care of with better algorithms. What I'm showing is just naive brute force path tracing without any filtering and other improvements applied (there are already some optimizations in the code to make it render MUCH faster). The video shows that the quality is acceptable at hd resolution (720p) in under one second. The blur is only temporary. It's entirely possible to render noisefree at high framerates and resolutions with some cleverness, it'll just take some time ;-)Sam Laperehttps://www.blogger.com/profile/05688552048697970050noreply@blogger.comtag:blogger.com,1999:blog-7277449027963623452.post-46270725525793337512012-02-24T03:39:35.597-08:002012-02-24T03:39:35.597-08:00hallo, i like the effort you invest
