BrepDiff: Single-Stage B-rep Diffusion Model

DescriptionWe present BrepDiff, a simple, single-stage diffusion model for generating Boundary Representations (B-reps). Our approach generates B-reps by denoising point-based face samples with a dedicated noise schedule. Unlike multi-stage methods, BrepDiff enables intuitive, editable geometry creation, including completion, merging, and interpolation, while achieving competitive performance on unconditional generation.
