// NAME
//  VisTransform4x4.cpp -- basic geometric transformations
//
// DESCRIPTION
//  The CVisTransform4x4 class represents geometric transformation
//  in 4-D homogeneous coordinates (projective space), in a manner
//  similar to that used in 3D graphics packages such as
//  OpenGL.  A 4x4 homogeneous coordinate matrix is used to represent
//  the mapping between one or more points in the world to each
//  screen pixel.
//
//
// SEE ALSO
//  VisResample.h     image resampling algorithm
//  VisGeometry.h     coordinate transformation chains (stacks)
//
//  Vision Library      Technical Note No. 1 (Vision Technology Group)

// BUGS

//
// DESIGN
//  Jeremy deBonet suggested that CVisVector4 and CVisTransform4x4
//  be derived from CVisDVector and CVisDMatrix.  This is a reasonable
//  idea, as it cleans up the class structure, at the cost of a slight
//  loss in efficiency in accessing vector/matrix elements.
