Looks like I managed to remove 747 thousand lines of code in 2019. Major cheating, since half a million of that was versioned Quicktime SDK headers that we no longer need.

and a couple of screenshots:

New tiny blog post, now that Clang 9 is out: "Clang Build Analyzer" https://aras-p.info/blog/2019/09/28/Clang-Build-Analyzer/

I tried my "toy path tracer" on iPhone 11 Pro, just for kicks.
- CPU multi-core 25.2 Mray/s
- CPU single-core 10.0 Mray/s
- GPU 90.4 Mray/s

Compare: 2018 MacBookPro 2.9GHz:
- CPU multi-core 64.5 Mray/s
- CPU single-core 12.9 Mray/s
- GPU 213.4 Mray/s

I'll write about it more once Clang 9 is fully out (soon-ish), but here's a little tool I scribbled together: Clang Build Analyzer. https://github.com/aras-p/ClangBuildAnalyzer

"fun" C++ quiz time. what will this program print? (and why?)

"CreativeAI: Deep Learning for Computer Graphics" #SIGGRAPH2019 course material is online: http://geometry.cs.ucl.ac.uk/creativeai/

Blender 2.80 is out, and is a very impressive update. https://www.blender.org/download/releases/2-80/

It is extremely cool that even on the other side of the world of #SIGGRAPH2019, one can read "Path Tracing in Production" and "Path Guiding in Production" course notes just like that. ~200 pages of excellent material. https://jo.dreggn.org/path-tracing-in-production/2019/index.html

Ok, so HBO Chernobyl is the greatest miniseries of all time.

Fun fact: some of the KGB prison scenes were shot in the same building as what Unity Kaunas (first non-Copenhagen R&D office!) was back in 2008. It was not fancy at all, back then we had no $ okay? :)

"Leveraging Ray Tracing Hardware Acceleration In Unity" is nice. https://auzaiffe.files.wordpress.com/2019/05/digital-dragons-leveraging-ray-tracing-hardware-acceleration-in-unity.pdf #digitaldragons2019

"The Making of The Heretic: Digital Humans and VFX Characters" is really good: https://docs.google.com/presentation/d/1aiBXsNu-D9ZfpBNqcs08w7ToNJ2e7jgyoyfNUXSCWW8/edit?usp=sharing #digitaldragons2019 #madewithunity

Profile Analyzer for Unity. https://blogs.unity3d.com/2019/05/13/introducing-the-profile-analyzer

I made a toy path tracer for triangle meshes. Used it as an interview task ("make the initial version faster!") https://github.com/aras-p/ToyMeshPathTracer

So! I'm told there's a Unity build with raytracing (DXR) goodies, i.e. HD render pipeline with optional raytracing for various bits. Here on github: https://github.com/Unity-Technologies/Unity-Experimental-DXR

Whoa, looks like I've been in build system team for two years already. Time flies! Here's a blogpost, with some neat tools we've built. https://aras-p.info/blog/2019/03/08/Two-years-in-a-build-team/
