Spirula Studio meshes the splats inside the room (clean.py --outside); the result stands upright with the
floor at height 0 – Z up for OBJ/PLY/STL, Y up for GLB. Texture when the training images are still there.
Tested on real scenes (kitchen without images: colours per corner; textured on one with images) and with a
fake spirula mesh in the tests (579 passing). Not done yet: look at the dialog in the browser, changelog,
README, release.
