256 x 256 x 240 pixels and 256 x 256 x 207 pixels. Each model was rendered in
two modes: with no semi transparent pixels and with semi transparent pixels. Semi
transparent pixels were used for simulation tissues with low density (in example
skin). The speed of rendering was measured (in frames per seconds) for different
popular screen resolution. The results were summarized in Table 7 and in
Fig 10.
