As graphics researchers or geometry teachers, we speak about 3D using screenshots, and that's just sad... What if you could make SLides on top of PolyscOPE? You can using SLOPE! Slope allows you to synchronize a 3D viewer, animated meshes, shaders, live demos, equations (& more) with your slides!

I know nothing about GPU programming, so I thought that BSP-OT on the GPU would not work because we are recursive then sequential... I asked Claude to give it a try in CUDA: x10 speed-up 😳 0.4s for 350k points in 3D, with the same quality as the CPU 😱 Here is the code: github.com/baptiste-gen...

At the end of my internship at Adobe, we could not release code for numerous reasons. But I thought that the pseudo-code in the paper would be enough for anyone to re-implement it! I was wrong 🫠 @arezdev.de contacted me a week ago, asking why his implementation did not work...

My implementation of the paper "Implicit UVs: Real-time semi-global parameterization of implicit surfaces" from @baptiste-genest.bsky.social. The paper describes a way to texture SDFs in realtime by letting the user place seeds on the surface which get blended into a global UV space #godot #Graphics

Yep I'm been playing with the BSP-OT solver and it is quite fast. The following interpolation is done on 300k samples and only takes a few seconds (but can only find permutations). Generating the GIF/animation is slower than solving the problem.

When dealing with noisy and/or partial inputs to describe a shape, the standard approach in geometry processing is to reconstruct a clean implicit surface first, and to do geometry on it. But why this one in particular? What about all the other surfaces that would have been coherent with the input?

For those interested in normalized gradient methods and optimal transport: I introduce a new class of "spectral" Wasserstein distances for which spectrally normalized gradient descent (Muon but without momentum and small step size ...) is a spectral-W gradient flow: arxiv.org/abs/2604.04891

Muon Dynamics as a Spectral Wasserstein Flow

Gradient normalization is central in deep-learning optimization because it stabilizes training and reduces sensitivity to scale. For deep architectures, parameters are naturally grouped into matrices ...

Happy to share the excellent work of @baptiste-genest.bsky.social on making sliced optimal transport *much* better by replacing the sort along a line with a variant of QuickSort that directly takes multiples directions at once! It also directly provides a coupling between points.

Computing the exact bijection of the optimal transport (OT) problem between very large point sets is completely untractable… In our SIGGRAPH Asia 2025 paper: “BSP-OT: Sparse transport plans between discrete measures in log-linear time” we get one with typically 1% of error in a few seconds on CPU!

"The greatest trick the Binomial ever pulled was convincing the world it didn't behave exactly as expected."

If N is a Binomial random variable with parameters n and p, then the expected value of "N choose k" is "n choose k" time p raised to the k-th power.
