Preparing episode 6 for the Voxel Ray Tracing in C++ series, of which the first 5 episodes are available on my blog:

https://jacco.ompf2.com/author/jbikker/

Path tracing requires a tiny algorithm, but it produces some stunning results. Hopefully the article is done on Wednesday.

I released my code to write/read styles for @ocornut's Dear ImGui to .ini-like textfiles or to C++ code as a standalone MIT-licensed source file that's easy to integrate into any project using Dear ImGui with C++: https://github.com/DanielGibson/Snippets/blob/master/imgui_savestyle.cpp

It's for v1.90.6, but is easy enough to adapt to other versions, as it helps you doing that with a bunch of static assertions that check struct ImGuiStyle and enum ImGuiCol_ for changes.

A good reason to use colour rather than color in your code is that colour has the same number of letters as both albedo and normal so you can align your code better.

This voxel displacement technique for "modern retro" rendering looks so incredible, really inspiring:

I've quietly made my LayerProcGen framework public:
https://github.com/runevision/LayerProcGen

It's a framework (C#) that can be used to implement layer-based procedural generation that's infinite, deterministic and contextual.

Nobody else have tried/tested it yet - if you're up for taking it for a spin, let me know how it looks; what's clear or confusing, if you think there's low hanging fruit improvements I could make, etc.

"When you look at the northern sky, you can follow the arm of the Big Dipper as it arcs around toward the bright star called Arcturus. Roughly in the middle of that arc, you'll find the Northern Crown constellation, which looks a bit like a smiley face. Sometime between now and September, if you look to the left-hand side of the Northern Crown, what will look like a new star will shine for five days or so."

If you're using Visual Studio 17.10 you can go to Tools > Options and then search for Copilot to turn off all the stupid LLM bullshit.

I can't get over how wonderful these molecular machines animations are.

But more pressingly, I can't get over how mindboggling and fascinating this stuff really is. These are molecules, swarms of atoms, that just happen to "do certain work" following the laws of physics and chemistry, which after "some time" turned out to become Life.

I'm often looking for analogies to explain this emergence. Conway's Game of Life is clearly one.

Do y'all think of this stuff?

New episode (number 5 already!) in the series on Real-time Voxel Ray Tracing in C++:

https://jacco.ompf2.com/2024/05/22/ray-tracing-with-voxels-in-c-series-part-5/

This time the topic is reprojection. This is a complex topic and thus a lengthy episode.

"Surprisingly, our results show that women's contributions tend to be accepted more often than men's. However, when a woman's gender is identifiable, they are rejected more often. Our results suggest that although women on GitHub may be more competent overall, bias against them exists nonetheless."

Final video for now, newer videos another day :)

This all happens on a 6000km radius voxel planet with overhangs, floating islands, deep caves, sunsets, stars, nebula and a bunch more not shown.

Build on the surface, underground, in the air or in space. All streamed, no tricks.

Added @troy_s's AgX tone mapping to Avoyd Voxel Editor, based on @benjamin's code.

This is an initial implementation and there may be some issues, but the beta is available for those who have access.

I am excited to finally share our recent paper "Filtering After Shading With Stochastic Texture Filtering" (with Matt Pharr, @marcosalvi, and Marcos Fajardo), published at ACM I3D'24 / PACM CGIT, where we won the best paper award! 1/N

For folks that know me as "the blue noise guy", I've put together a 50 minute video that talks about many of the things I've learned in my ~decade long dive into noise and related topics - up to and including our latest paper published days ago at I3D.
I hope you enjoy it!

A slide showing how random numbers which are positively correlated on the screen give correlated resulting renders, uncorrelated random numbers give uncorrelated renders, and negative correlation random numbers give negatively correlated renders. Negatively correlated renders have the best perceptual quality, despite all three having the same actual error.

This GH issue is pretty funny, but seems to have finally gotten the ball rolling on the Wayland side after the threat/worry that SDL 3.0 might not support Wayland natively (more specifically, it would not select SDL's Wayland backend by default) due to some issues that made it untenable for games. https://github.com/libsdl-org/SDL/pull/9345

Avoyd 0.22 beta adds a 3D Viewport to the Voxel Editor. This makes it easier to frame renders.

The venerable Voyager 1 spacecraft is experiencing another glitch. Instead of sending science and engg. data, it is sending a 0101 bit pattern.

The problem has been narrowed down to the flight data system (FDS), which is not communicating properly with the telecom unit (TMU). A reboot did not help.

Stay tuned as NASA engrs work out a fix for this 1970's era computer, which has performed magnificently during its long 46-year journey to the planets and to outer space.
