Detailed Description

template<bool Shared = false>
class farsa::wVectorT< Shared >

wVector class

\

Motivation

4 dimensional Vector of real numbers; useful for transformation matrix, quaternion and 3d points and vectors.

Description

This class has a template parameter which allows to choose whether to have inner data or shared data. In case of shared data this can only be constructed using the constructor having a pointer to a vector of real as a parameter.

Warnings

When it is used as 3-dimensional vector the fourth value is set to 1.0
