| |
| This 3D primitive expands the SdrPrimitive3D to a 3D rotation definition. |
| The given 2D PolyPolygon geometry is imagined as lying on the XY-plane in 3D |
| and gets rotated around the Y-Axis. |
| |
| Various possibilities e.g. for creating diagonals (edge roudings in 3D) |
| and similar are given. |
| |
| The decomposition will create all necessary 3D planes for visualisation. |
