Detailed Description

Generates 3D geometry for an identified or selected feature on top of the terrain mesh.

Points become spheres, lines become extruded tubes with sphere joints, and polygons get both an outline and a semi-transparent triangulated fill. The geometry is reprojected from the source CRS to the map CRS before being draped on the terrain surface.

Note:

QML Type: Qf3DGeometry

Public Types Documentation

enum AltitudeClamping

enum Qf3DGeometry::AltitudeClamping {
    Ignore,
    ClampToGround,
    Absolute
};

How the geometry's Z values interact with the terrain elevation when computing the vertical position of every emitted vertex.
