🛠️ TetWeave can be used in many applications:
✅ Mesh compression
✅ Geometric texture generation
✅ Photogrammetry
(8/9)

🏆 Results? TetWeave guarantees watertight, manifold, and intersection-free meshes, and outperforms FlexiCubes and DMTet in memory efficiency and mesh quality. (7/9)

👁️ Because we compute the grid on the fly, the point cloud can be located anywhere! We develop a resampling strategy that allocates more points where they matter most (like highly detailed regions) based on rendering error or customizable approaches. (6/9)

🎛️ We introduce a notion of directional signed distance, encoded as spherical harmonics on each grid vertex. This allows precise vertex placement and sharper details! (5/9)

💡 TetWeave solves this by dynamically constructing the grid via Delaunay triangulation! Our representation simply consists of a point cloud with an SDF value. To reconstruct a target mesh from images, we jointly optimize the grid and the signed distance at each point.

🔍 Methods like DMTet or FlexiCubes jointly optimize the implicit representation and the grid structure from which the final mesh is extracted. However, they rely on grids with fixed topology, which leads to memory inefficiency and poor scaling. (3/9)

🤔 Meshes are ubiquitous in computer graphics. However, their fixed topology and the difficulty of recovering from a bad state make them a poor choice for gradient-based optimization pipelines, such as 3D reconstruction. (2/9)

I remember playing this game! Such a great one!!

For me it’s somewhat in the middle of afternoon, so I tend to cherish this time slot to go to gym :D

PorcelAIn!

Will AI be able to create porcelAIn pieces of artwork? 😉 At least it'd make a good AI company name

Really beautiful! Is it done by hand? 😯
