Constructor & Destructor Documentation

template<typename T>
RayGina::CORE::RMatrix4x4< T >::RMatrix4x4 (   )  [inline]
 

Default constructor. Assign the default value T() to all elements (== 0 for basic types).

Definition at line 43 of file RMatrix4x4.inl.

template<typename T>
RayGina::CORE::RMatrix4x4< T >::RMatrix4x4 (  T  value  )  [inline, explicit]
 

Initalizes all elements with the given value.

Parameters:
value the value to assign. Note: Explicit usage only to prevent assigning a value with '='-Operator.

Definition at line 52 of file RMatrix4x4.inl.

template<typename T>
RayGina::CORE::RMatrix4x4< T >::RMatrix4x4 (  const T *  data  )  [inline, explicit]
 

Copies the data from data (16 values). Assumes row-wise ordering, e.g. {1,0,0,0, 0,1,0,0, ... } for the identity.

Definition at line 61 of file RMatrix4x4.inl.

template<typename T>
template<typename R>
RayGina::CORE::RMatrix4x4< T >::RMatrix4x4 (  const RMatrix4x4< R > &  other  )  [inline]
 

Template-Constructor. Does not hide the (default-)copy-constructor !
