How to view ply in supersplat #44

Open HuangTY96 opened 7 months ago

HuangTY96 commented 7 months ago

Hi, This work is perfect, but the result cannot be displayed in those existing tools like supersplat and unity. Do you have any ideal to deal with this problem?

fantasy-fish commented 3 months ago

Any update on this?

tongji-rkr commented 3 months ago

We will soon release the anchor version of 3DGS, and the training results can be converted to standard 3DGS.ply files, which can be used in web viewer and UE5

@tongji-rkr How is going of 'anchor version of 3DGS'? It's really usefull for showcase online.

tongji-rkr commented 2 months ago

We propose Octree-AnyGS, a general anchor-based framework that supports explicit Gaussians (2D-GS, 3D-GS) and neural Gaussians (Scaffold-GS). Additionally, Octree-GS has been adapted to the aforementioned Gaussian primitives, enabling Level-of-Detail representation for large-scale scenes. This framework holds potential for application to other Gaussian-based methods. Please refer to https://github.com/city-super/Octree-AnyGS.

@tongji-rkr

Checked the project: https://github.com/city-super/Octree-AnyGS.

Lack of the document and "The SIBR viewers is coming soon". So how "...converted to standard 3DGS.ply files..." with Octree-AnyGS?

tongji-rkr commented 1 month ago

Each anchor in the anchor version of 3D-GS can be converted to a SH0 Gaussian, which I think does not depend on the SIBR viewers.

I think the main problem lies in how to obtain the spherical harmonic coefficients of orders 1-3, because rgb colors can be easily obtained, corresponding to the spherical harmonic coefficient of order 0.
