Detailed Description

template<typename T>
struct mitsuba::TPoint4< T >

Parameterizable four-dimensional point data structure.

Member Typedef Documentation

Constructor & Destructor Documentation

template<typename T>
mitsuba::TPoint4< T >::TPoint4 ( )
inline

Construct a new point without initializing it.

This construtor is useful when the point 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.

template<typename T>
mitsuba::TPoint4< T >::TPoint4 ( x,
y,
z,
w 
)
inline

Initialize the point with the specified X, Y and Z components.

template<typename T>
template<typename T2 >
