mesh

The shift from 2D-lifting to native 3D generation. Autoregressive mesh transformers (MeshGPT, MeshAnything) and flow-matching latent models (Trellis, Hunyuan3D-2, TripoSG). Architectures, tokenization, conditioning, and which ones are actually usable in 2026.

What it takes to ship a generated mesh into a real game, AR app, or animation: topology cleanup, retopology, LODs, auto-rigging, and the 2026 platform landscape across Meshy, Tripo, Rodin, CSM and others.

A working map of the 3D representations that matter in 2026 — meshes, point clouds, voxels, SDFs, NeRFs, and 3D Gaussian Splatting. What each one is, when each wins, and why mesh output still anchors production pipelines.
