The Fourier projection-slice theorem allows projections of volume data to be generated in O(n2 log n) time for a volume of size n3 . The method operates by extracting and inverse ...

This can be a costly operation. When the data is arranged according to its three-dimensional coordinates, calculating the contour surfaces requires examining each data cell. Avoidi...

In this paper we advocate the use of a focal regionguided feature-based volume renderer that offers an alternative for visualization of internal structures of volumetric data. We ...
