LookSee Quest app shows models misaligned

[Tom Goddard]

If I open two atomic models and align one to another (open 7rfw, open 7dvw, mm #2 to #1) and Send to Quest with LookSee v3 the two models are far away from each other (30x molecule diameters). The GLB file displays correctly aligned in BabylonJS sandbox web viewer. So it is probably not a mistake in the GLB file. It may be a problem with how LookSee is scaling and centering the model, or it may be a bug in the GLTFast reader.

Instead of matchmaker, just translating the second model by 1 Angstrom (move x 1 model #2) seems to move the two models 1 meter apart in the initial VR view.

Appears to be a bug in my rescaling in LookSee. It is rescaling the mesh vertices and that is not taking account of an offset from the transform, so different meshes get scaled about different centers. I scaled the mesh instead of changing the transform because of an earlier bug where scaling by large factors (100000?) caused rendering problems reported by Mike Schmid. So probably I should just fix the scaling center and still scale the mesh.

Fixed. Released LookSee version 4.

The mesh scaling was fine. The trouble was that the position offset scaling only handled the first two levels of the game object tree. It needed to scale positions at all levels of the tree.
