VertexRegen: Mesh Generation with Continuous Level of Detail

TL;DR

VertexRegen is a new mesh generation framework that allows continuous level of detail, enabling anytime generation with valid meshes at any intermediate step, inspired by progressive meshes and learned through a generative model.

Contribution

It introduces a novel approach to mesh generation by reformulating progressive mesh techniques as a learned vertex split process, enabling continuous and flexible level of detail.

Findings

Produces meshes of comparable quality to state-of-the-art methods.

Offers anytime generation with valid meshes at any intermediate step.

Demonstrates flexibility and quality in experimental results.

Abstract

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.
