a little vase we printed with filament we made to emulate the look of lambertian shading, where it’s lightness is determined by it’s surface normal and it’s dot product with a light vector

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

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.

As 3D generative AI matures, it’s reshaping creativity across multiple disciplines.

This year, ever-expanding work in the 3D generative AI space will be explored as part of the SIGGRAPH Technical Papers program, including these three novel methods — each offering a unique take on how 3D generative AI is being applied.

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.

Wrote some more about extending the "HAKMEM 149 line algorithm" to a quad rasterizer to be able to draw billboards (sprites) up to 3D sprites, the HAKMEM approach (and forward mapping) lose a bit of interest when degrees of freedom (and projection) are added up though but it was fun to retrace the sprites history a bit.

A great new article by Jeffrey Starr, Investigating MacPaint's Source Code: https://ztoz.blog/posts/macpaint-source-code/

#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.

A very simple way to draw HAKMEM 149 based structures by using whole 32 bits range with upper bits as coordinates using unsigned shifts.

This also works with a lower range but it loses precision.

The oblique version is even simpler by removing the last two operations.

The structure looks like Apollonian net or Hopalong attractors.

This drawing method also works with other attractors or Gingerbread man map etc.

When matsuoka-601 dropped his WebGPU fluid simulation demos, they left everyone in awe—pushing the limits of what's possible in the browser with breathtaking realism and incredible performance.

Now, he's been kind enough to take us behind the scenes, breaking down the magic behind the mesmerizing waves, high-performance physics, and real-time rendering!
