[Bug - Proj Mesh3D] #2219

Open ftoromanoff opened 9 months ago

ftoromanoff commented 9 months ago

Linked to the PR #2180 that changed the way base_alti is handled, we noticed a difference in the representation of object in the 3D environnement. Take the examples source_file_gpx_raster and source_file_gpx_3d that both use a gpx file to draw it on a itowns scene. The first one project it on the raster layer when the second one draw it as a mesh. We exept the 2 way to show very similar view. Or (already before) that's not the case moreover the newly merge PR make it even more different (see example following)

On master before merge: tilt: 45 image tilt: 0 (Nadir) image

On master after merge: tilt: 45 image tilt: 0 (Nadir) image

I propose a fix in PR #2223. Might not be the best in regard of efficiency but we get back the same result as we had in master.
