Yesterday on stream we've sketched out most of the support code for descriptor heaps. If you want to see the rest of the owl, I've committed the remaining pieces after the stream. For now all of the previous descriptor code is still required to support production drivers.

A little bear figurine carved out of amber some 6,000 years ago 🐻❤️
A hole runs through the bear’s torso suggesting it was threaded on a cord, perhaps worn or carried as a protective charm.
Found in a peat bog near Słupsk, Poland, in 1887.

While working on spark.js, I realized that common normal map compression formats weren’t supported in popular frameworks like three.js. I added the necessary support to three.js and wrote an article to shed some light on the topic:

This feels like the texturing version of spinning around my model.
Playing with carve groups in @marmoset3d.bsky.social to get grey metalness values through intermediate oxidation.

Finally finished Gatling's Metal backend! Here's a teaser of NVIDIA's USD / MDL sample scene 'Attic' running on macOS. What's special about the backend is probably that it uses the same GLSL code as the Vulkan backend, complete with hardware ray tracing. How does that work?

🤔 What if you could skip painful subdiv modeling and paint your knurls instead?
@oddenough.art demonstrates a fast, non-destructive workflow using Toolbag’s vector layers and symmetry mode to create and refine knurling patterns in no time.

Dear ImGui now embeds a vector/scalable version of the classic font by default, manually subsetted/optimized so it fits in 18 KB (opt-out possible). Embedding ensures easily and readily usable in all contexts. Should default to new one on most setups. Here's a compare of both. #ChristmasMiracle
