There are now 9 articles, all with full source code. :) 4: animation; refitting and rebuilding a BVH. 5: TLAS & BLAS; this is how RTX/DXR handles BVHs for games. 6: TLAS & BLAS part 2 (5 was getting too long). 7: Using the BVH for nice rendering. 8: Whitted-style ray tracing, with an HDR skydome...

I am working on a series of blog posts on constructing a BVH, in straight 'sane' C++, with source code on Github: https://jacco.ompf2.com/2022/04/13/how-to-build-a-bvh-part-1-basics/ and https://github.com/jbikker/bvh_article Three articles have been released so far: * Basics * Faster rays *...

The video is actually from the older version of the benchmark, and it indeed has an editing mistake. In the new benchmark the noise is no longer stationary. I find the stationary noise easier on the eyes, but a lot of people find it very distracting.

I have uploaded a new version of the demo. This one has far better noise characteristics: image quality of the regular RTX version (10 spp) now exceeds the quality of the 'RTX2' (24spp) executable of the original release. Performance also improved: the 10spp version runs at about the speed of...

It doesn't support dual cards. If Nvidia sends me some hardware I will implement the feature.

The mighty RTX 6000 has fallen. Strangely enough two RTX 2080 Ti's beat it; I don't think they are overclocked either. Driver issue perhaps? I do wonder now how the Titan RTX perrforms.

Results are absolutely affected by overclocking.

Very nice. :)

A new path tracing benchmark with RTX support is available from: https://jacco.ompf2.com/lighthouse-2-rtx-path-tracing-benchmark The benchmark also runs on pre-RTX hardware, although performance is lower. If you own a device that is not in the list I would love to hear your performance results...
