Major update to our continuous cluster lod rendering sample. Reduces memory consumption for ray tracing by not keeping vertex positions resident and rely on fetch intrinsics. Thanks to Calvin Hsu for investigations on this. We also improved the path tracing a bit. www.github.com/nvpro-sample...
Slides for SIGGRAPH 2026 Advances in Real-Time Rendering in Games course's talk on SMOLDER — REAL-TIME VOLUMETRIC EFFECT RENDERING IN GLACIER AND 007 FIRST LIGHT by @lexdev.net from IO Interactive are now online - enjoy!! advances.realtimerendering.com/s2026/index....
A Texture Lookup Approach to Bézier Curve Evaluation on the GPU jcgt.org/published/00... New published paper! The premise is that you can offload polynomial evaluation to the texture sampling unit, which can be useful for improving execution times if you are compute bound.
So many new features in vk_gltf_renderer (github.com/nvpro-sample...) since my last post, I'll drop a few highlights. - glTF 2.1 External Assets - Releases: compiled version of the sample - PBR: better volume scattering, retroreflection - Optimizations: material compile defines - Opacity Micromesh
At #SIGGRAPH2026, I presented "points as tori" (PAT) for fast pointwise evaluation of signed distance for point clouds. Some code (Python w/ C++ extensions) and demo up: github.com/nzfeng/point... Contributions from people/LLMs welcome. Explainer thread below for the project: 🧵
New random sampling method for three-gpu-pathtracer: blue noise dither sampling! It offsets a common random sequence for ALL screen samples, yielding a cleaner image in just a few samples. Screenshots are single sample scrambled sobol vs blue noise. Small writeup below👇
dear imgui 1.92.9 released! github.com/ocornut/imgu... - new liveedit on/off settings and defaults - tables track topology changes - metal4 rendering backend - timestamped settings entries (for cleanup etc.) - 50+ other changes/fixes (fonts, multi-select, popups, backends etc.).

meshoptimizer 1.2 is out! Featuring support for tangent generation, a significantly faster vertex decoder for Intel/AMD CPUs, several new smaller algorithms (cluster position compression, triangle filtering, clusterlod BVH) and more. GitHub stars and boosts appreciated! github.com/zeux/meshopt...
Reminder that the coding help I need the most for Dear ImGui are related to tech that are foreign to me: Vulkan, OSX, Metal, Android, Linux. Many open issues/pr, need quality brain time, design time, explanations & reviews to close topics rather that have more opened: github.com/ocornut/imgu...

Half the stuff in the new build exist purely so I can show off that we have shadows in the DOOM engine nowadays.
Shipshapes for a cancelled animated project. A recurring theme.
I implemented multiple fixes & improvements in Vulkan/D3D12 Memory Allocator libraries, on my fork for now. If you use any of these, please give it a try so we validate they work fine before I turn them into official releases. github.com/sawickiap/Vu... github.com/sawickiap/D3...

@spacegooose.bsky.social I loved the space car and needed to try it for myself. I resized for 8.5 x 11 and printed on regular weight paper. This was my first paper craft and it was really fun to make even if i made some mistakes in quality towards the last bit #papercraft
I'm a little late to the party on this one since it's from January, but I just read this great blog post by Jure Triglav walking through implementing surfel-based global illumination. It's got a bunch of really cool interactive toys/visualizers! juretriglav.si/surfel-based...
Ok, new sokol-sample for Slug text rendering is out! This has been ported from this Odin sample with some quick'n'dirty improvements (most notably: batching for glyphs) tangled.org/dosha.dev/so... WebGL2 sample: floooh.github.io/sokol-html5/... ...and WebGPU: floooh.github.io/sokol-webgpu...

dear imgui 1.92.8 released! github.com/ocornut/imgu... - many fixes/improvements for tables, text inputs, axis auto-sizing, multi-select & box-select, clipper, key ownership system etc. - ImDrawList::AddRect() sig change⚠️ - Bonus: a renderer agnostic standard for changing texture sampler.
