显示三维体


  • view perpendicular cross-sections of 3-d volumetric data and adjust the rendering to reveal structures within the volume.

  • view 3-d labeled volumetric data, and adjust the visualization such as the opacity and colormap, using the volume viewer app.

  • interactively clip a quadrant of a volumetric image to expose a surface within the volume.

  • adjust the transparency of labeled volumetric data and the rendering style to reveal labels on the interior of the volume.
