Detailed Description

template<class T>
class gml::TMatrix3x3< T >

Template class for 3x3 matrix.

    a0  a3  a6 
    a1  a4  a7
    a2  a5  a8

Member Function Documentation

T* RawArray (   )  [inline]

Provide access to internal contents. Warning: Use with care, this function is dangerous!

void SetTranslation (  const TVector2< T > &  t  )  [inline]

Set translation part of this matrix to values of vector t. Translation part is the 3-th column, so it is valid for use with column-vectors V = M * V; V = (v1 v2 v3 v4)T See also: MultMatrixVec
