This work presents a scheme to directly genera te manifold, polygonal meshes of arbitrary connectivity as the output of a neural network. Our key innovation is to define a continuous latent conne ctivity space at each mesh vertex, which implies the discrete mesh. In par ticular, our vertex embeddings generate cyclic neighbor relationships in a halfedge mesh representation, which gives a guarantee of edge-manifoldnes s and the ability to represent general polygonal meshes. This representati on is well-suited to machine learning and stochastic optimization, without restriction on connectivity or topology. We first explore the basic prope rties of this representation, then use it to fit distributions of meshes f rom large datasets. The resulting models generate diverse meshes with tess ellation structure learned from the dataset population, with concise detai ls and high-quality mesh elements. In applications, this approach not only yields high-quality outputs from generative models, but also enables dire ctly learning challenging geometry processing tasks such as mesh repair.\n \nRegistration Category: Full Access, Full Access Supporter\n\nLanguage Fo rmat: English Language\n\nSession Chair: Noam Aigerman (University of Mont real) URL:https://asia.siggraph.org/2024/program/?id=papers_635&sess=sess130 END:VEVENT END:VCALENDAR
