Table 3.

Frame rate measurements, using combinations of 2D and 3D views covering the full screen

Layout	Frame rate (fps)	Render time (ms/f)
9 $\times$ 2D	60	17
1 $\times$ 3D+6 $\times$ 2D	20	50
2 $\times$ 3D+5 $\times$ 2D	12	83
Video + any	60	17

All views contained 2 volumes and a segmented model. The video view was used in various combinations with the same result. The 3D and video views use VTK rendering algorithms, while the 2D views use a custom renderer
