With the 3D views bridges and tunnels are rendered on the hight of the terrain, instead of the objects

[DDzwiedziu]

Description

In the 3D view roads on bridges and tunnels are rendered following the terrain shape, not their actual shape.

This is the Ponc Viaduc https://wikiless.northboot.xyz/wiki/Passerelle_(Luxembourg) and below is the view in OsmAnd

Steps to reproduce

Look at any bridge or tunnel.

Actual result

The object is drawn along the terrain curve.

Expected result

The object is shown at it's actual height.

Your Environment (required)

OsmAnd Version: 4.8.5
Android/iOS version: Android 14
Device model: Asus Zenphone 11/AI2401 H
Crash-Logs: not a crash

The height above or below ground isn't known, so the only option would be to guess/estimate it.

[pebogufi]

A good estimation would be the average of the values before and after the tunnel.

[DDzwiedziu]

A good estimation would be the average of the values before and after the tunnel.

Or draw a line in 3D space between the entrance and exit and use that for approximation.

The issue has been successfully reproduced. To replicate it, go to coordinates 49.60561394289059, 6.133672699373974, load the Terrain map (3D), and tilt the map downward using two fingers.

As a result, in the 3D view, the bridge is incorrectly displayed at the terrain level instead of at the height of the bridge structure.
