Fast BVH construction and maintenance, with a very compact API. New version adds SBVH with "unsplitting" for ultimate BVH quality.

Last week I released on github a new single-header file library for constructing and traversing BVHs on the CPU, with (short-term) plans to take traversal (not construction) to the GPU as well. Features: * No dependencies at all. Just add t

Third episode of the Voxel Ray Tracing in C++ tutorial. Describes ray tracing techniques using a fast CPU template / framework. Covered so far: lights, shadows, reflection, refraction. Third article covers stochastic techniques: anti-a

Hi Roel. :) Was a pleasure to work with you!

Very nice. :) Every language deserves its own ray tracer!

You mean it looks funny in Safari without that setting? I am learning a ton about wordpress caching plugins, after last night's HN deluge... Perhaps I can do a tutorial on that next. ;)

That must have been very recently then? IIRC, until two years ago there was ray tracing, then rasterization, in that order. As it should be. :) Anyway if you're in Utrecht there's a nice 'Advanced Graphics' course. Best

Well if you have more than 2 levels you can always collapse, which is the preferred solution. Just walk the scenegraph, and flatten the matrices. Now you're left with an array of BLASses, each with their final matrix. RTX has hardware

This is the sixth article on building a bounding volume hierarchy on the CPU, completing the original planned series. Two more articles are now planned, taking this to the GPU, but still without using RTX.

Article 4 (on refitting) and 5 (constructing BLAS + TLAS) should arrive this week, completing the basic C++ implementation of the algorithm used for DXR / RTX.
