LookAt Transform Initializer and Oblique Section Image Filter

Abstract

This paper describes the ITK implementation of a transform initializer to produce a rigid 3-D transform able to center a given point on an arbitrary plane. The resultant transform allows the user to "look at" a point from a given direction. The resultant transform can also be used to obtain an oblique section: a single arbitrary 2-D slice through a 3-D image.
