📜 New SIGGRAPH 2025 paper 🎉

❔How to compute bounding volumes for procedural Signed Distance Fields (SDFs)? This is not so trivial!

💡We propose a simple method called Sphere Carving. It extracts (convex) bounding volumes around SDFs, requires very few evaluations, and is GPU compatible.

OPEN SCIENCE IS THE FUTURE!

Very pleased to see the Association for Computing Machinery (ACM — the parent organization to my “home” conference SIGGRAPH) has announced it is transitioning to full open access by January 2026!!

I am glad to attend #HPG2025 where I just presented our paper "Fused Collapsing for Wide BVH Construction", co-authored with Mathias Paulin. We propose a fast build algorithm for wide BVHs that directly computes a wide hierarchy without additional collapsing pass. Webpage: wbrbr.org/publications...

Thank you so much for your feedback 🤗🤗🤗 I was very lucky, the ideas were very simple and worked very quickly. From the first ideas to the submission it took around 4 months and a half🙏

Thank you so much for your comment🙏🙏 it means the world to us🤗

Thank you! It's really nice of you🙏

It was made during an intership at @adobe.com
. This is a joint work with Pierre Gueth, Jérémy Levallois and Stephanie Wang, who supervised me during my internship. Many thanks to them!

Here is the submitted version of the article: baptiste-genest.github.io/papers/impli...

You can then use these coordinates to enhance SDF rendering with textures, normal maps, and even displacement maps!

You also can use it with shell maps to define a 3D coordinate system from the 2D ones, and more!

We use concepts from differential geometry to first define local uv-fields that are evaluatable point-wise. We then show how we can merge multiple fields into larger ones to get high quality uv-fields on large smooth patches of the shape.

We introduce the first method to compute uv coordinates on implicit surfaces, without discretization, in real-time in a sphere-tracing pipeline!

It allows you to get full control over the appearance of the shape, with textures, without losing the benefits of implicit representations!

Implicit surfaces are great, but if you are not Inigo Quilez, it's really hard to control how they look...

That's why I'm really proud to annonce our Eurographics 2025 paper: "Implicit UVs: Real-time semi-global parameterization of implicit surfaces".
