¥These data sets form matrices
with one column representing the node index (ni, a.k.a
node id) followed by p values (i_val. 1
É i_val. p) associated with each node.
¥Those p values can
potentially be any assortment of parameters, though some dataset
formats will be limited.
¥In some instances, the node
index column may be missing and the nodeÕs index is
assumed to be equal to the row index.
¥Unlike its volumetric
counterpart, the domain over which the data are defined is not
implicitly defined in the dataset.
HSuch a dataset alone
cannot be visualized without specifying its surface domain
(location and connectivity of the nodes).
¥Dsets can be colorized
(mapped to a colormap) offline using ScaleToMap (the olde way)
or interactively (the in way) using SUMAÕs Surface Controller
interface.
¥A colorized data set is
called a Òcolor planeÓ.
