It is designed to operate directly on B-rep data structures, avoiding the need to approximate the model as meshes or point clouds. BRepNet defines convolutional kernels with respect to oriented coedges in the data structure. In the neighborhood of each coedge, a small collection of faces, edges and coedges can be identified and patterns in the feature vectors from these entities detected by specific learnable parameters.","description_state":"present","introduced_year":null,"introduced_by":{"title":"BRepNet: A topological message passing system for solid models","paper":"/paper/brepnet-a-topological-message-passing-system","first_author":"Joseph G.
