Calculate the surface area of a structure. Isosurface constructs a triangular surface mesh by marching cubes and calculates the bone surface area (BS) as the sum of the areas of the triangles making up the mesh. The surface mesh can optionally be displayed in a 3D Viewer window.

- Input
- Options
- Resampling: how much resampling to apply to the stack while creating the surface mesh. A low number results in an accurate but jagged mesh with many triangles, while a high number results in a smooth mesh with fewer triangles.
- Threshold: pixel value to use as a surface cutoff
- Show surface: if checked, draw the mesh in a 3D Viewer window
- Save as binary STL: writes STL of mesh triangles directly to disk. If 'Show surface' is unchecked the mesh is not displayed - this can be useful for large meshes.
- Output
- Image: image title
- BS: bone surface area
- Interactive 3D surface mesh (optional)
- Binary STL file written to disk (optional)
