Detailed Description

General purpose 4D vector class.

Representation of a 4D vector, defining operations to access, modify and perform calculations on 4D vectors. This class uses double precision floating-point numbers for represent its data, and in its operations. There are seperate similar classes for 2D and 3D vectors, CSIBCVector2Dd and CSIBCVector3Dd, respectively, which also use double precision.

Furthermore, there is another set of vector classes which use single precision floating-point numbers, CSIBCVector2D, CSIBCVector3D and CSIBCVector4D for 2D, 3D and 4D vectors respectively. Quaternions represented as 4D vectors are also available in CSIBCQuaternion and CSIBCQuaterniond with single precision and double precision, repspectively.
