I just posted the second part of my series on writing a debugger in Rust! In this part, I've implemented a simple console interface, register display, and stepping instructions.

I've gotten some of the final quirks worked out of the fog material for three-gpu-pathtracer including the fireflies which were from subsequent specular hits.
Demo here!

I always like it when someone just takes some images, encodes them, looks at the results, and shares their opinion. "If I had to choose a format to re-encode all of my photos, I would for sure choose JXL."

After the NE and the LE, the Portable Executable that we still use was created.
First in x86 32bit but also 64bit, PowerPC, Alpha, Itanium, Arm64...
There's often an extra 'Rich' header that stores xored (why!?) build information between the Dos Stub and the PE header.

I've released a cut-down version of the #GLSL SDF code for the hand I made in my Terminator 2 shader (shadertoy.com/view/mdt3D7), thinking someone might find it useful. :)

🎅 Today, we have an early Christmas present for you: SDF Studio. Building on the fantastic code, we have integrated various implicit surface reconstruction techniques in one common framework! autonomousvision.github.io/sdfstudio/
More algorithms and results coming soon..

I've been having fun with SIMD of late, specifically in Rust, so if you're interested in Rust, SIMD, ISPC, and how to benchmark them I've put together an introduction.

I continue to be amazed at the pace of #3D research. Below, a 3D avatar is constructed by an algorithm with nothing but a short 2D vid to go off which has had no special preparation done to it. Read the full paper from (+ soon get the code!) here: moygcc.github.io/vid2avatar/

motivated me to make the thing I was long thinking about: an online Gaussian blur kernel weights generator. It outputs sample weights & offsets to be used with linear filtering to reduce the number of texture reads by a factor of 2.

TabFS is a browser extension that mounts your browser tabs as a filesystem on your computer.
omar.website/tabfs/
By Omar Rizwan - this is pretty genius. Get all your tabs as files on your HD, so you can use terminal scripts and other access patterns to do batch processes.

This is by far the most astounding tech demo I’ve seen in a long time. Provides a totally different, amazing POV on how we should think about language/compiler/debugger/runtime/editor as an integrated whole.

When a drop falls into a pool of liquid, it creates a distinctive cavity, followed by a jet. From above the surface, this process is well-studied. But this poster offers us a glimpse of what goes on beneath the surface, using particle image velocimetry.

I have just finished refactoring TinySTL, the code is much cleaner now, split into multiple files instead of a single large file 😄 , also examples are now moved to their own repo., see links 👇⬇:

If you want to use the original uvs from the geometry there is a issue on uv seams but if you use polar based uv the transition is smooth because every geometry is going to be parameterized to sphere first.

Are able to transfer uvs as well?
