🔎Excited to share our PDT: Point Distribution Transformation with Diffusion Models (SIGGRAPH2025)! 💡While autoregressive models are now widely adopted for predicting structures, we find diffusion models can also reveal high-level structures by transforming point distributions!

Introducing ✨RigidFormer: Learning Rigid Dynamics with Transformers - our attempt to scale learning-based physical dynamics with Transformers. RigidFormer learns rigid dynamics with Transformers. It is a mesh-free, object-centric Transformer for multi-object rigid-body contact dynamics from point clouds. Learning physics with purely neural simulators, without relying on traditional physics engines, is an important and widely studied problem. Prior SOTA methods often use graph neural networks for accuracy and generalization, but still struggle with efficient, high-fidelity simulation at scale. RigidFormer uses only point inputs, matches or outperforms mesh-based baselines on standard benchmarks, runs much faster, generalizes across point resolutions and datasets, and scales to 200+ objects. We also show a preliminary extension to command-conditioned articulated bodies by treating body parts as interacting object-level components. RigidFormer is mesh-free: it does not require mesh connectivity, SDFs, or vertex-level message passing, making it well-suited for point-cloud observations and scalable simulation. This architecture can also be adapted to learn soft-body dynamics by replacing the rigid-body module (differentiable Kabsch alignment). 🎬See our video for more details. Many thanks to my amazing collaborators: Minghao Guo @GuoMh14, Haixu Wu @Haixu_Wu_1998, Doug Roble, Tuur Stuyck @TuurStuyck, and Wojciech Matusik @wojmatusik.

Excited to share that our work NeuralActuator: Neural Actuation Modeling for Robot Dynamics and External Force Perception has been accepted to #RSS2026! Your robot — even a low-cost one — can feel external forces without torque or tactile sensors. TL;DR: NeuralActuator is a neural actuator model that jointly predicts 1️⃣torque to capture the nonlinear and time-varying current–to–torque relationship of low-cost servos, 2️⃣external contact forces (and force detection gates) for sensorless force perception, 3️⃣and motor conditions that indicate each motor’s operating regime. Here is a fast-forward video clip ⬇️ We are also covering more robots like LeRobot-S101 and Franka Panda. More details coming soon.

SAD: Soft Anisotropic Diagrams for Differentiable Image Representation has been accepted by #SIGGRAPH2026 Check it out, and huge congrats to Lucky! @Luckyballa #SAD represents an image as a soft, anisotropic, differentiable diagram over learnable sites. Each pixel is modeled as a softmax blend over its top-K nearby sites under a site-dependent distance, yielding a differentiable partition of unity with explicit ownership and content-aligned boundaries. A GPU-friendly top-K propagation scheme keeps the cost constant per pixel, enabling fast fitting at matched or better quality. Classical geometric structures can still inspire fresh perspectives in modern visual computing. Voronoi and Power diagrams have long been elegant tools for 3D shape analysis, reconstruction, and geometric reasoning; here, related diagram ideas, with connections to Apollonius-style diagrams, are explored for image representations.

We present EgoReAct: Real-time 3D human reaction generation from streaming egocentric video. 🌟Reacting to streaming egocentric video is something humans do every day. We hope EgoReAct makes human motion more human-like. 🔎 What we found: existing ego-reaction data can be spatially inconsistent (e.g., moving reactions paired with fixed-camera videos), which breaks 3D grounding. 📷 What we built: HRD, a spatially aligned egocentric video–reaction dataset (3,500 pairs, 32 categories), plus a spatially aligned ViMo fix for fair evaluation. (Instead of collecting expensive ground-truth motion, we employ VDM to generate the egocentric videos.) 👁️⚡🏃 Our simple yet effective pipeline: motion tokenization for compact discrete codes + an autoregressive Transformer for online, strictly-causal generation. Metric depth and head dynamics further improve 3D spatial consistency.

Welcome to check out our spotlight paper at NeurIPS2025!🌟
Zhiyang (Frank) Dou@frankzydou

Please check out paper #MOSPA "🎧Human Motion Generation Driven by Spatial Audio” at #NeurIPS2025 (🌟Spotlight)! 😊We have released our dataset and models : ) 💡The paper tackles the challenge of spatial-audio-driven human motion generation, enabling virtual humans to respond dynamically and realistically to diverse spatial sounds — not just “what” is sounding, but also “where” and “how” it sounds in space. 💡We introduce SAM, the first comprehensive Spatial Audio-Driven Human Motion dataset, with diverse spatial audio scenarios and high-quality 3D motion pairs, providing a solid benchmark for studying human motion conditioned on spatial audio. 💡Building on this, MOSPA is a diffusion-based generative framework that fuses semantic and spatial features of the audio to synthesize diverse, realistic motions aligned with spatial audio cues, achieving state-of-the-art performance on this new task and offering a strong baseline for future research. If you work on virtual humans, spatial audio, XR, or humanoid / embodied control, this can be a good motion skill learning source. Please come meet the team at our #NeurIPS2025 San Diego Spotlight poster! 📍 Exhibit Hall C,D,E — #4310 🕚 Fri, Dec 5 | 11 a.m.–2 p.m. PST Homepage: frank-zy-dou.github.io/projects/MOSPA… Paper: arxiv.org/abs/2507.11949 Code and Data: github.com/xsy27/Mospa-Ac… #NeurIPS #NeurIPS2025 #MOSPA #motion #Animation #SpatialAudio #VirtualHuman #Robotics #Robot #AI #Deeplearning #GenerativeAI #AIGC

Here is some new footage from this paper, offering a glimpse into the future of dynamic 3D Gaussian Splatting models combined with static reconstructed scenes. Imagine this: when the lighting matches, the result becomes practically indistinguishable from reality. Just pick a scene, add characters, and record it from any angle. Apply diffusion models to instantly change the look. I firmly believe this is the future of VFX.

AHA! Animating Human Avatars in Diverse Scenes with Gaussian Splatting Contributions: • We introduce the 3D Gaussian Splatting representation to the classical computer graphics problem of animating humans in 3D environments. • We demonstrate that our framework can be used for geometry-consistent free viewpoint rendering of monocular videos edited with new animated humans. • We introduce a novel Gaussian-aligned motion module for motion synthesis in scenes represented as 3D Gaussians. • We introduce a human scene Gaussian refinement optimization for the correct placement of human Gaussians in scenes represented using 3DGS, leading to better contact and interactions.

Excited to share our latest work on 🎧spatial audio-driven human motion generation. We aim to tackle a largely underexplored yet important problem of enabling virtual humans to move naturally in response to spatial audio—capturing not just what is heard, but also where the sound is coming from. To this end, we introduce the Spatial Audio-Driven Human Motion (SAM) dataset—the first comprehensive dataset featuring paired high-quality human motion and spatial audio recordings. For benchmarking, we develop a generative framework for human MOtion generation driven by SPAtial audio, termed MOSPA, which learns to synthesize realistic and diverse human motions conditioned on spatial audio input. We hope this research could provide a foundation for future research in spatial perception, virtual characters, and embodied AI. The dataset and model will be open-sourced soon. A big thank you to our intern, Shuyang Xu, for the wonderful collaboration! Congratulations, Shuyang!

Check out our #ICCV2025 paper VertexRegen! Instead of the typical incomplete meshes you get with autoreg mesh gen, VertexRegen generates progressively more detailed meshes as the generated sequence gets longer. vertexregen.github.io Great work by xzhang.dev
