Can this method be extended to export a mesh?

Hi, thanks for your great work.

While viewing the results in WebGL, I noticed that the surfels can already reconstruct the overall geometric contours of the scene quite well, and the Gaussians further enrich the fine details. This made me wonder: could your method be extended further to support mesh reconstruction or mesh export?

I think that would make the representation even more useful for downstream geometry-related applications.

Thanks in advance.

Thanks for your interest in our work.

Compared with meshes, the biggest difference of surfels is that they do not explicitly encode topology. This makes them easier to optimize, but it also makes it more difficult to directly extract an iso-surface from them.

A simple solution is to directly tessellate each elliptical surfel into triangles, or to use triangles as the basic primitive from the beginning. We are also exploring better ways to convert our representation to meshes more directly.

Thanks again for the insightful suggestion.
