What's up with the bunnies? They consist of spheres. :) You can now combine triangles, custom geometry, and multiple BVH layouts all in one TLAS, in both single and double precision. This does not affect perf of the default path (i.e. triangles only scenes).
Soon on the dev branch of tionybvh: https://github.com/jbikker/tinybvh/tree/dev

What is the correct FOV to use in a game?

Think of your monitor as a window. Lines from your eye to the monitor (in the real world) should continue in the same direction in the virtual world.

You get this by taking the angle between the two solid lines: This is the correct FOV.

The default field of view in Starfield is 85. This may be correct, depending on how large your monitor is, and how close you are to it.

Helldivers 2 uses a vertical FOV of 55: roughly 85 vertically on a 16:9 monitor.

The #thisisigad C/C++ TMPL8 has been updated to 2024, with better OpenCL support, a 3D scene graph (via @syoyo's tinygltf/obj).

And: Several examples, many of which my (former) students will recognize. :)

Updated: bvh_article source repo, at:
https://github.com/jbikker/bvh_article
Now with full OpenCL 3.0 support.

This takes you from basic CPU-side triangle intersection to real-time CPU ray tracing, and via basic GPU OpenCL first-hit to massive TLAS/BLAS. My poor UHD620. :)

TL;DR: Too hard to learn; many people stick with OpenGL. In the meantime, a colleague at my university asked if it would be safe to basically switch to path tracing altogether for year 2 courses next year, using the APIs to render 2 tris essentially...

https://jacco.ompf2.com/2024/05/29/ray-tracing-with-voxels-in-c-series-part-6/

This time: Path Tracing. Including: BRDF & pdf, the random bounce, cosine-weighted bounce and verifying ground truth.

Path tracing requires a tiny algorithm, but it produces some stunning results. Hopefully the article is done on Wednesday.

New episode (number 5 already!) in the series on Real-time Voxel Ray Tracing in C++:

https://jacco.ompf2.com/2024/05/22/ray-tracing-with-voxels-in-c-series-part-5/

This time the topic is reprojection. This is a complex topic and thus a lengthy episode.

Episode 4 of the series on Voxel Ray Tracing in C++ is now online:

https://jacco.ompf2.com

In this episode: improving soft shadows using stratification and blue noise. As always, it starts with the template, available from Github: https://github.com/jbikker/voxpopuli

Episode 3 of the Voxel Ray Tracing in C++ series is now available:

https://jacco.ompf2.com/2024/05/08/ray-tracing-with-voxels-in-c-series-part-3/

This time: stochastic techniques; anti-aliasing, the accumulator, soft shadows. And: scene loading.

In this episode we add recursive reflections and refraction with Snell's law and Fresnel. With the included template, everything runs in real-time on your CPU.
