Detailed Description

3 Class derived from Qt3DRender::QGeometry that represents polygons tessellated into 3D geometry.

Takes a list of polygons as input, internally it does tessellation and writes output to the internal vertex buffer. Optionally it can add "walls" if the extrusion height is non-zero.

Since: QGIS 3.0
