About

TriSplat is a research model for sparse-view 3D scene reconstruction. It replaces the Gaussian primitives used in most feed-forward splatting networks with oriented triangle primitives, so the output can be exported as a standard mesh without TSDF fusion or Poisson reconstruction. The project is by authors from Zhejiang University, ETH Zurich, ETH AI Center, Microsoft and Monash University (arXiv:2605.26115).

From sparse input images, a DINOv2-backed transformer decoder predicts dense local 3D point maps, relative camera poses, optional intrinsics and per-pixel triangle attributes. Triangle orientation is anchored to geometry normals, which are refined by an image-conditioned normal head. Opacity and edge-blur schedules start soft and sharpen progressively during training. At export, low-opacity triangles are dropped, face winding is corrected and nearby vertices are merged. The resulting meshes can be loaded into physics engines, collision detectors and standard renderers.

The project page offers an interactive demo with agents moving on exported mesh surfaces, plus a mesh gallery. Web versions are cropped and sampled, so they show holes that the offline exports do not have. A YouTube review states that the code is released and the model files are about 4.4 GB. No repository or weights link was available in the provided material, so those details are unverified.
