Been working on voxel ray-tracing again lately, this time using a BVH2 TLAS and SVT64 (64tree) BLAS(s). The heat gradient in the video shows the step count from 0 to 128. This scene contains 256 voxel dragons, each model is 256^3 voxels :)

My "No Graphics API" blog post is live! Please repost :) www.sebastianaaltonen.com/blog/no-grap... I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

Absorbing this knowledge is oddly soothing on this day of social chaos.

So honored to see The Knightling on this beautifully reflective GOTY list! A great gift, right on time for the holiday season😍 And what a list to be on!

Whirl for(float i,z,d,h;i++<8e1;o+=vec4(9,5,h+t,1)/d) {vec3 p=z*normalize(FC.rgb*2.-r.xyy),a;p.z+=9.;a=mix(dot(a+=.5,p)*a,p,sin(h=dot(p,p/p)-t))+cos(h)*cross(a,p); for(d=0.;d++<9.;a+=.3*sin(a*d).zxy);z+=d=length(a.xz)/15.;} o=tanh(o/1e4);

Super interesting game. Looking forward to it.

Not sure how to classify this game. What genre is it even - a herd-em-up? It's gorgeous is what it is. Very intrigued. Well done @benthroop.com ! www.youtube.com/watch?v=Qtf2...

Over 4 years ago I wrote an article about trying to solve the texture seam you often get in shader generated UVs. Especially in things like equirectangular UVs, though any kind of discontinuity will cause them. bgolus.medium.com/distinctive-...

[Leaving X] .... DONE Goodby to my 10000 followers, so long X, and thanks for the fish ! My stream of computational physics news / hardware engineering / geek stuff will continue here: - www.linkedin.com/in/blevy/ - fosstodon.org/@BrunoLevy01 - bsky.app/profile/brun...

My general recommendation: don't ever miss a talk by Chris Wyman, regardless of the topic.

Cem Yuksel's update to the teapot model looks great with a glass material! #metalrt #rendering

I wrote a new article, this time exploring a bit how some games handle refraction. I discovered quite a few interesting tricks ! www.froyok.fr/blog/2024-12... #gamedev #rendering

Posting an older article on "Probability Theory for Physically Based Rendering", using tomorrow's #thisisigad Graphics Guild lecture as an excuse: jacco.ompf2.com/2019/12/11/p... There is also a part 2.

The z-buffer and depth testing (aka z-testing) have been the dominant way of hidden surface elimination for over 50 years, introduced but not implemented in W. Straßer's PhD thesis in 1974, and actually implemented in Ed Catmull's PhD thesis in the same year. 1/4

I've settled on using a simple utility that wraps D3D's SetStablePowerState to stabilize GPU clock rate when profiling using in-app timers. This simple program does the trick: github.com/milkru/gpu_c... This should even work when profiling, e.g., WebGPU apps in browser! [cont]

Final version for the 2D Morton decode functions. Fairly happy with the structure in general. A 64-bit version should be easy enough to produce, by just using the 32-bit version twice and combining the results.

Just realised that a side-effect of putting up those spline tests the other day is that my Spherical Harmonics library test viewer is also available: andrewwillmott.github.io/app/DemoApp.... If you should need to play around with SH coefficients or rotations for some reason.

After nine years of development, meshoptimizer has reached its first major version, 1.0! This release focuses on improvements in clusterization and simplification as well as stabilization. Here's a release announcement with more details on past, present and future; please RT! meshoptimizer.org/v1

The post on using spatial hashing with raytraced ambient occlusion attracted quite a bit of interest so I expanded it into a blog post to discuss how it works behind the scenes to both reduce the noise and its cost. interplayoflight.wordpress.com/2025/11/23/s...
