Detailed Description

Class representing a 4x4 transformation matrix.

CSIBCXfoMatd is a specialized 4X4 matrix that represents transformations. It uses double precision floating-point numbers for its data, and operations (as it is derived from CSIBCMatrix44d).

Although transformations may be defined simply with any generic 4X4, this class provides extra methods to make specifying and working with transformation matricies easier. A class for general transformations, independent of matrix form is provided in CSIBCTranfod.

There are several other matrix classes aswell. Classes with specific applications, such as CSIBCRotMatd used for representing rotation matricies, Other matrix classes are not as specialized as CSIBCRotMatd or CSIBCXfoMatd, and are used to represent general matricies. These classes include CSIBCMatrix4x4, CSIBCMatrix44d and CSIBCMartrix33d.
