How to get the generated and optimized mesh model？

waczjoan commented 7 months ago

Hi, Please find "Tutorial" section in README, We put there step by step instruction, based on hotdog dataset. If you have any trouble, I will be happy to help. Also, if there is something written that is not clear - please let me know -- I will be happy to fill in the missing information for other users as well.

@waczjoan Hi, First of all, thanks for the good work and really appreciate make it open source.

I'm wondering what exactly your gs_mesh output is ? Can we get a mesh file like .obj ? Or the result is till 3DGS pointcloud (.ply) but with mesh face constrain making 3DGS more "structure" ?

@homee-dennis thank you!

The output closely resembles what 3DGS generates, with the possibility of returning extra data depending on the chosen model. For instance, it may include enumerated vertices/pseudomesh, or in the case of gs_flame, it provides vectors enabling the utilization of the FLAME model. I recommend delving into the project and paying attention to the additional_attrs within the "save_ply" method in specific model.

There have been inquiries about whether the model yields an .obj file. Currently, it does not, as parameters like vertices and faces suffice for our purposes. However, I am considering sharing a script that converts these values into an .obj file for those who are interested :)
