Is Ray Tracing Making Game Development Better? (We Think It Is!)

> There's been a few games in recent months that require ray tracing capable GPUs to play. Turns out, there's a pretty good reason

Released version 1.6 of my QuickDraw view application.
The most significant change is support for pattern operations.

I published the shape manipulation demo on GitHub so that others could experiment with it. Once again, I used Gemini CLI a lot to convert the source code. It's incredible to see what's possible!

I converted a C++ sample project for shape manipulation to Swift, using CBLAS and LAPACK libraries. This could be useful for manipulating organelles. However, I first need to write a triangulation of shapes.

How to render a mesh gradient using RBF interpolation

https://www.notion.so/Smooth-Mesh-Gradients-with-RBF-Interpolation-1ba8eeb5a3e68046b34cf997fe67d3c1?source=copy_link

I tried out some new methods for the transformation, particularly focusing on the extreme points. Also closed paths are pretty nice.

The BioRender brushes look great. I've always wondered how easy it would be to create graphics like this. First, I transform the curves along the path. Before that, I replaced straight lines with cubic splines.

In a world where graphics nerds drool over pixels, "The Book of Shaders" offers a multilingual guide to making your computer generate prettier noise. It's like a toddler's first steps—except the toddler is a computer, and the steps are incomprehensible shader code.

Doing this was cool in the 80s and nowadays it continues to be cool. Mesh in BASIC.

Breakthrough ideas start here.

The SIGGRAPH 2025 Technical Papers program showcases the latest innovations in computer graphics and interactive techniques.

When: August 10–14, 2025
Where: Vancouver, Canada

It's crazy how advanced the graphics software on Symbolics LISP machines were in the 1980's before SGI kind of took over that space.

Is there a standard algorithm to create a halftone screen from a greyscale image? How was this even done before computers?
I mean like in this image. At 50%, the raster is like a checker board, and at darker tones, it's like white circles on black.
So just drawing black circles won't get you there.

#GIMP version 3.0 has been released a few days ago. Obviously this was an absolute monster of a release that was years in the making.

As someone who uses this application A LOT, this is great! It will take a while after I’ve discovered the new features.

Sebastian Lague has a new video up -this time on planet-sized flued simulations (sort of): https://www.youtube.com/watch?v=8nIB7e_eds4

Hero Wavelength Spectral Sampling successfully implemented!

Both: 4 samples per pixel
Left: one wavelength per ray
Right: four wavelengths per ray

With only a modest increase in runtime duration, the image becomes much smoother. This is more efficient than just adding more samples per pixel!
