The user can then view the overall structure throughout a data set. Opacity allows the user to set the transparency of the pixel values which are displayed in applications which render with transparency. Currently this is only VolumeView, and Opacity may only be called from a button on that application. VectorView is a prototype of a generalized vector field exploration tool. Currently, it only handles scalar fields as input, then takes the gradient of those fields for analysis.
Profile displays the data values along a line drawn on a slice of data.
The slice may be from any view axis of Image, or from the Combine or Compare tools. The line is drawn with a pencil shaped cursor called from the menu of the drawing application, which must be linked into Profile. Data base, slice and endpoint information are all given. The left side of Profile corresponds to the initial point of the line. The Profile window stretches in either direction, with the plot rescaling accordingly.
