This makes it easier to transmit them over the network and allows for progressive image refinement. The transmitted 2-D cross-sections are then transformed and reconstructed into a 3-D volume. ...
For this we need to extract sub-volumes of the data set. These sub-volumes are then transmitted and rendered at a higher resolution than the rest of the data set. ...
After transforming the data set in x-direction (Figure 4), this 3-D array is then transformed along the y-direction (Figure 5). Finally, the 3-D array is transformed along the z-direction. ...
