Monday mornings are for solving hard problems!

Because "why not", I made my toy path tracer run in the browser via WebAssembly. Was pretty easy! http://aras-p.info/blog/2018/11/16/Pathtracer-17-WebAssembly/

The most excellent and lamentable tragedy of Flat UI Design, in two acts.

I updated my toy path tracer Unity C# Burst code with a 4-wide HitSpheres implementation. PC 84->133 Mray/s, Mac 36->60 Mray/s. http://aras-p.info/blog/2018/10/29/Pathtracer-16-Burst-SIMD-Optimization/

Is good Friday. Removing https://github.com/aras-p/hlsl2glslfork and https://github.com/aras-p/glsl-optimizer from Unity main codebase, since we stopped using them a while ago. They served a good purpose between 2010 and ~2017, but time to let go.

It took a while, but Terrain system and tooling in Unity is getting some updates ;) https://blogs.unity3d.com/2018/10/10/2018-3-terrain-update-getting-started/

I did a talk on Entity Component Systems & Data Oriented Design for junior/future engineers here at Unity (not Unity specific at all). Slides: http://aras-p.info/texts/files/2018Academy%20-%20ECS-DoD.pdf and toy project (C++) for it: https://github.com/aras-p/dod-playground

The t-shirt says the truth.

Evening 7: spaghetti code.

Evening 6: fractals, fractals everywhere.

Another evening of secret production: I don't know where I'm even going with this. 🤷But hey, learned about "Kali Set" fractals :)

Day 4 was jolly scenes and other stuff. Also, I forgot how hard it is to do all this! Apparently practice is needed :)

Day 3 was more textures, more learning of Timeline, Particles, etc. etc. Everything still looks like shit, halp!

Day 2 was kid making fonts & textures, while I was trying to figure out how to use this "Unity" thing :)

Day 1 of surprise secret project: mostly storyboarding and references.

Disney has released full data set of Motunui island from Moana movie: https://www.disneyanimation.com/technology/datasets

Matt Pharr has an excellent blog series on making pbrt better at rendering it. http://pharr.org/matt/blog/2018/07/16/moana-island-pbrt-all.html

Look at that. Nesting, variants, prefab mode. https://unity3d.com/prefabs

Pathtracer part 14: I made it run on iOS, both CPU & GPU parts. Some info on Xcode GPU performance tools, and a tiny bit of NEON code. http://aras-p.info/blog/2018/05/30/Pathtracer-14-iOS/

Daily Pathtracer part 12: buffer-oriented approach on the GPU. I produced some accidental garbage renderings, and learned some nsights. http://aras-p.info/blog/2018/04/25/Daily-Pathtracer-12-GPU-Buffer-Oriented-D3D11/

Daily Pathtracer part 11: let's try a "buffer oriented" approach (is that what "wavefront" or "stream" tracing is? I don't know!) http://aras-p.info/blog/2018/04/19/Daily-Pathtracer-11-Buffer-Oriented/

Next up: maybe try the same on a GPU
