Constructor & Destructor Documentation

template<typename T>

mitsuba::TVector4< T >::TVector4 ( )

inline

Construct a new vector without initializing it.

This construtor is useful when the vector will either not be used at all (it might be part of a larger data structure) or initialized at a later point in time. Always make sure that one of the two is the case! Otherwise your program will do computations involving uninitialized memory, which will probably lead to a difficult-to-find bug.
