New · Nine-Part Practical Course
Geometry, AI & 3D Printing
Go from mesh fundamentals to printable solids, PyTorch3D augmentation, tokenization, diffusion, model routing, texture preservation, and production QA.
Geometry · AI · VFX · Digital fabrication
The hidden machinery of editable 3D
Research notes for artists and engineers who want to understand not only which mesh tool to click, but what the tool is solving and how to build better workflows around it.
Course · Part 01
From Mesh to Manufactured Object
Representation contracts, three masters, measurable checkpoints, manufacturing manifests, and choosing GLB, STL, or 3MF for the job.
Geometry Processing · Chapter Two
Differential Operators, Surface Signals, and the Hidden Mathematics of Mesh Editing
Gradients, divergence, cotangent Laplacians, mass matrices, curvature flow, Poisson reconstruction, and harmonic coordinates—built from visual intuition upward.
Course · Part 03
Print-Ready Meshes
Watertightness, manifoldness, wall thickness, overhangs, orientation, scale, tolerances, and a useful Trimesh inspection script.
Spectral Geometry
What Frequencies Mean on a Mesh
Why Laplacian eigenvectors behave like a shape’s natural harmonics—and how that changes smoothing, compression, segmentation, and search.
Course · Part 05
Mesh Augmentation with PyTorch3D
Safe transforms, sampling, geometric corruption, supervision contracts, deterministic batches, and surface-aware losses—with code.
Course · Part 06
Mesh Tokenization for Transformers
Coordinate quantization, face ordering, adjacency-aware sequences, MeshGPT, MeshAnything V2, and why token budgets shape topology.
Course · Part 07
Diffusion on Meshes and DMTets
Fixed volumetric scaffolds, signed-distance parameters, diffusion training, marching tetrahedra, conditioning, and production limits.
Course · Part 08
Choose AI 3D Models by Representation
TRELLIS.2, Hunyuan3D 2.1, mesh tokens, DMTets, candidate filtering, and a practical production router.
AI Production Pipeline
Image to 3D to Paint to Retopology—Without Losing the Surface Story
A practical chain for turning generated concepts into editable, painted geometry while keeping UVs, material intent, and production provenance intact.
Model Field Notes
TRELLIS.2 or Pixal3D?
A practical comparison of PBR image-to-3D reconstruction, local RTX 5090 deployment, API pricing, and print-ready workflows.
