UVTran: Transformer-Based Hole-Filling for N-Sided Surfaces
UVTran, a novel transformer-based framework, tackles the issue of N-sided hole filling in industrial design. This approach introduces an auxiliary projection surface to enhance the capture of geometric features at hole boundaries, addressing the shortcomings of conventional projection methods that often overlook boundary diversity. Utilizing B-spline locality, UVTran integrates a cross-attention mechanism that directs each surface control point towards the adjacent hole boundary, thereby maintaining local geometric precision. The framework converts control-point coordinates into a voxelized format and frames the challenge as a learning task, with the goal of increasing fairness and minimizing filling errors. This research is available on arXiv with the identifier 2605.16306.
