VertexRegen: Mesh Generation with Continuous Level of Detail
Authors: name: Xiang Zhang, name: Yawar Siddiqui, name: Armen Avetisyan, name: Chris Xie, name: Jakob Engel, name: Henry Howard-Jenkins

We introduce VertexRegen, a novel mesh generation framework that enables
generation at a continuous level of detail. Existing autoregressive methods
generate meshes in a partial-to-complete manner and thus intermediate steps of
generation represent incomplete structures. VertexRegen takes inspiration from
progressive meshes and reformulates the process as the reversal of edge
collapse, i.e. vertex split, learned through a generative model. Experimental
results demonstrate that VertexRegen produces meshes of comparable quality to
state-of-the-art methods while uniquely offering anytime generation with the
flexibility to halt at any step to yield valid meshes with varying levels of
detail.
