It was so good to be in Vancouver to present our work “Interactive Optimization of Scaffolded Procedural Patterns” at #Siggraph2025!

If you couldn’t make it, have a look at our project page!

Can’t wait for what’s next! 🎉

Join out talk on Thursday 14/08 in the "Packing In Structure" session at 3:45pm (West Building, Rooms 211–214) to see this in action!

The gradient-free optimization enables fast optimization over both continuous and discrete parameters, while GPU-accelerated SDF evaluation keeps the optimization loop interactive. Together, they let us achieve real-time interaction even for complex, highly parameterized procedural patterns.

Each new sketch triggers a gradient-free optimization process that minimizes a weighted per-pixel distance between the pattern’s SDF and the stroke SDF. The weights extracted from the both pattern and "Void" strokes enable focusing on drawn regions as well as empty ones.

We model a procedural pattern generator as a sequence of functions called Levels, where each Level’s parameters form a superset of the previous one
This enables coarse-to-fine optimization, where earlier parameters are inherited and new ones are optimized.

In our #SIGGRAPH2025 paper “Interactive Optimization of Scaffolded Procedural Patterns”, we introduce a new way to define and optimize procedural patterns in a sketch-based interactive design workflow.

SIGGRAPH Asia (still) coming up! Second paper thread!

"Direct Manipulation of Procedural Implicit Surfaces" where we explore how to create a WYSIWYG editing interface for procedural representations, avoiding awkward sliders!

🏆 So honored that our paper received the Honorable Mention #Award at #SIGGRAPHAsia!

I really like this paper BTW, it is about procedural #SignedDistanceFields, a simple idea to #differentiate them and thus provide #DirectManipulation ✨
