If anybody was wondering why I was playing with these "funnies" yesterday, here's the result: generating test-data for my data-parallel renderer (in this case 800M unique triangles, and a few million instances too, across two GPUs): ingowald.blog/2023/01/22/sil…

After all these many years since I first saw this ages ago….still my favorite error message ever. Glad it still exists…

"First light" for my experimental "optix-in-python" pyOWL experiments; using RTX-accelerated ray tracing on the GPU with python-interface for host-side scene setup. Still a lot of missing features, but I'd claim this is already recognizable :-)

Frozen puddle on our parking lot .... looks familiar!

After having _always_ built all my previous #modelships without any paint, today was the first time I put a paintbrush on my #hmssurprise… man, this first time feels totally surreal…but I do have to admit it kinda got something…

📜 Check out our paper on large scale memory-efficient adaptive mesh refinement data with a high-quality interpolant. ✍️ Stefan Zellmann, Qi Wu, Kwan-Liu Ma, Ingo Wald 👉 pds.uni-koeln.de/sites/pds/szel… #Fullpaper #EuroVis #Eurovis2023

We dropped the source code for our 2023 EuroVis paper on AMR dual grid rendering on Github: github.com/owl-project/ow…; including several different AMR volume samplers, volume path tracer, and majorant-based acceleration structures. Talk tomorrow afternoon, at #EuroVis2023

New paper pre-print for our HPG23 paper (with Milan Jaros and Stefan Zellmann) on data-parallel multi-gpu path tracing: sci.utah.edu/~wald/Publicat…. Main thing for this method is just how super simple it actually is.

Wow. After our dog went crazy around our vacuum cleaner all day long my son finally got my tools and opened it….

Believe it or not: I just had a server - after seeing my Nvidia shirt - tell me “thank you for your work, in making the video games I so much enjoy”…

Treat for Peter Shirley 🔮🛡 : python version of your RTOW example, using my latest python bindings for ANARI github.com/ingowald/pynar…

Now THAT is an art installation that a ray tracing guy can appreciate…

Look! Ingo Wald was made my Christmas dream come true! (I have always wanted fast Python ray tracing) ingowald.blog/2024/12/13/pyn…

pynari on Mac ... Still "somewhat experimental" (this Mac literally arrived this morning!) - but this looks about right 😎

The Utah Symphony and David Robertson surpassed themselves tonight: 5 standing ovations and 2 encores. Jurassic park was one of the best performances I’ve ever heard (in any format), and Adkins’s Schindler solo - just out of this world… Williams would be proud indeed!

Happy Valentines Day ray tracing lovers!
