摘要
我們提出了VertexRegen，這是一種新穎的網格生成框架，能夠實現連續細節層次的生成。現有的自回歸方法以部分到完整的方式生成網格，因此生成的中間步驟代表的是不完整的結構。VertexRegen從漸進式網格中汲取靈感，將生成過程重新表述為邊緣摺疊（即頂點分裂）的逆過程，並通過生成模型來學習這一過程。實驗結果表明，VertexRegen生成的網格質量與最先進的方法相當，同時獨特地提供了隨時生成的能力，具有在任何步驟停止以產生具有不同細節層次的有效網格的靈活性。

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.
