Better area splatting

Feature Request
1

Gaussian splats within Scaniverse are perfect when going around an object, however, when we’re talking about a whole area, meshes are way better.

I tried both splatting an area using the current splatting option and reprocessing good area scans to splats, but results range from bad, to terrible.

For instance, a splat of an area:

The mesh equivalent is way cleaner (cannot post a pic yet because of a limitation on new users, but I’ll gladly do it in the replies).

Would there be any way of extending splatting so they support areas better?

I’m new to all this and curious, when you mentioned “reprocessing good area scans to splats” do you mean using the mesh option and then reprocessing to a splat in some other software, or in the app? Can you expand on that? Also, I’m using the Android app which lacks some of the features of the iOS version, and I actually don’t know what functionality I am missing. Thanks!

I mean reprocessing a mesh scan into a gaussian splat using the app, given extracting the raw data isn’t possible at the moment.

And yeah, I’m using the iOS version.

yes they come out botched like this. also, the navigation starts in this area where coverage is very limited.
One solution would be to edit starting location of the viewpoint ,but that’s not possible…

Hello, we appreciate you reporting your issue. If you saved the raw data of your scan, you could try to reprocess the scan as you previously mentioned. The option to reprocess a scan can be found by selecting a scan in your library, tapping on the three dots in the top right corner, and then pressing the “Reprocess scan“ button located in the bottom left corner. If the option is not there, then the raw data was not saved when you created the scan.

Additionally, do all your results from processing splats look worse than the mesh counterparts?

Hi, yes, when reprocessing the scans to be splats, they look significantly worse when those scans are of large areas.

Here is the mesh scan that was reprocessed to make the splat in the first post (still cannot link more than one image per post so this isn’t very practical):

Same data and everything, but seems Scanniverse’s implementation of splatting cannot deal with it.

Same with me. The point cloud preview looks good, but when I process it into a splat, it creates just a diffuse area around where I started. I don’t know if i should move slower or what causes the generation to be limited and not of the whole area that the preview point cloud shows.
