Topology-First B-Rep Meshing
YunFan Zhou, Daniel Zint, Nafiseh Izadyar +3
Parametric boundary representation models (B-Reps) are the de facto standard in CAD, graphics, and robotics, yet converting them into valid meshes remains fragile. The difficulty o…
LLM-Guided Material Inference for 3D Point Clouds
Nafiseh Izadyar, Teseo Schneider
Most existing 3D shape datasets and models focus solely on geometry, overlooking the material properties that determine how objects appear. We introduce a two-stage large language…
Neural Kinematic Bases for Fluids
Yibo Liu, Zhixin Fang, Sune Darkner +4
We propose mesh-free fluid simulations that exploit a kinematic neural basis for velocity fields represented by an MLP. We design a set of losses that ensures that these neural bas…
Emergent Crowds Dynamics from Language-Driven Multi-Agent Interactions
Yibo Liu, Liam Shatzel, Brandon Haworth +1
Animating and simulating crowds using an agent-based approach is a well-established area where every agent in the crowd is individually controlled such that global human-like behav…
Time of Impact Dataset for Continuous Collision Detection and a Scalable Conservative Algorithm
David Belgrod, Bolun Wang, Zachary Ferguson +4
We introduce a large-scale benchmark for broad- and narrow-phase continuous collision detection (CCD) over linearized trajectories with exact time of impacts and use it to evaluate…
Better STEP, a format and dataset for boundary representation
Nafiseh Izadyar, Sai Chandra Madduri, Teseo Schneider
Boundary representation (B-rep) generated from computer-aided design (CAD) is widely used in industry, with several large datasets available. However, the data in these datasets is…
