3D render mode

Choose how structures are drawn in the 3D view: point cloud, wireframe, or surface mesh.

The 3D render-mode controls appear on the toolbar while the centre panel shows the 3D structure view (an RTSTRUCT or SEG). They set how every structure is drawn:

• Point cloud — the raw contour/voxel points, the cheapest mode and the default.
• Wireframe — the reconstructed surface drawn as triangle edges, so occluded structures read through it.
• Surface mesh — the reconstructed surface as a solid, shaded mesh.

Switching mode changes only how the structures look, not which are shown; per-structure visibility and colour live in the RT/SEG inspector on the right rail.
