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

I haven't been to SIGGRAPH in-person in quite a while, but this seems like a cool event...

I'm unsure if I saw #ToyStory in its unfinished state at #SIGGRAPH, but I did see #Pixar's #TinToy short film in wireframe before its final release.

Tạo lưới Delaunay là một kỹ thuật quan trọng trong hình học tính toán và đồ họa máy tính. Kỹ thuật này giúp tạo ra các lưới hình học chất lượng cao, được ứng dụng rộng rãi trong mô phỏng kỹ thuật, phân tích phần tử hữu hạn và dựng hình 3D.

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

I am binormal.

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.

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

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.

Check out the award-winning research here: https://blog.siggraph.org/2025/06/siggraph-2025-technical-papers-awards-best-papers-honorable-mentions-and-test-of-time.html/

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.
