And so, the porting begins...

Rainbow cubes are back! It's likely many of you didn't know me when all my posts were showing rainbow cubes in a way or another... As I am preparing to port Workbench to VK, I am back to basics.

Small progress today: my GUI library system is partially working. Textures and picking are still missing though.

New post: Upsampling via Multisampling. The goal is to use an MSAA target in an interesting way for doing a 4x area upsample. filmicworlds.com/blog/upsamplin…

I write long functions and use brackets to create collapsible blocks within. With appropriate comments for the blocks, is more convenient than small functions, very readable, keeps the scope clean, and I find it trivial to maintain.

Here is a new blog post of mine, where I dive deep into the theory and math behind ReSTIR GI. Big thanks to Markus Kettunen for verifying the theory, reviewing the article, and catching a key detail I had missed. agraphicsguynotes.com/posts/understa…

And.... it's upside down 🤣

Some progress: the grid, selection, wireframe, light gizmos, reverse Z-buffer, path-tracer/raster compositing and a few more bits. It's all coming back together.

I am doing things I a rush lately. Hopefully a better structure will emerge from the mess and a rewrite will follow.

And boooom...

Components selection and editing work again.

The Vulkan porting is complete 🎉 The last missing piece was the primordial raster renderer, which I am not sure why I keep around :) All in all, it wasn't nearly as hard as I thought it would be.

this video has brilliant demonstrations and explanations of weird bokeh & penumbra effects called ' blistering', which despite having implemented renderers with bokeh and blurry shadows many times, ive never understood before. great stuff! youtu.be/MuvuxHXLzls?si…

It’s been a long break away from my projects. Work deadlines + sickness + low energy slow recovery… I think I’ll try to make some progress on light transport, at least for a bit. Workbench doesn’t handle many lights (not gracefully at least).

First rather naive implementation of Stochastic Light Cuts. Here comparing uniform sampling vs SLC with 1spp over 16,000 lights.
