[Insight-developers] coordinates of a pixel

[Luis Ibanez]

Hi,

This is an image that was sent to the mailing list
but was rejected because its size was over 40Kb      :-)

So the image is now at:

http://www.cs.unc.edu/~ibanez/Insight/DelaunayVoronoi.jpg

It is a contribution to the last week tcon discussion
concerning the coordinates of a voxel. The image at left
shows the region that should be called a voxel, that is
the region around a point of the sampling grid.

The image at right shows the Delaunay region over which
a trilinear interpolation is performed using the values
of the eight sampling points (voxels) that are on the
corners of the Delaunay region.
