TreeMeshGPT: Artistic Mesh Generation with Autoregressive Tree Sequencing

Figure 1 . Artistic meshes generated by TreeMeshGPT. Our method offers a novel sequencing approach for artistic mesh generation using autoregressive Transformer decoder by retrieving the next token from a dynamically growing tree structure. In our experiment with 7-bit discretization, TreeMeshGPT supports meshes with up to 5,500 triangular faces under strong point cloud conditioning. 12
