Detailed Description

template<class Scalar>
class ACG::SceneGraph::ACG::Matrix4x4T< Scalar >

Simple 4x4 Matrix. Inherited by GLMatrix.

Definition at line 98 of file MeshNode2T.cc.

Constructor & Destructor Documentation

template<class Scalar>
ACG::SceneGraph::ACG::Matrix4x4T< Scalar >::Matrix4x4T ( const Scalar  _array[16])
inline

setup matrix using an array of N*N scalar values. elements are ordered 'column first' (like OpenGL)

Definition at line 113 of file MeshNode2T.cc.

Member Function Documentation

template<class Scalar>
const Scalar* ACG::SceneGraph::ACG::Matrix4x4T< Scalar >::get_raw_data ( ) const
inline

access to data array. not very nice, but in case of 4x4 matrices this member can be used to pass matrices to OpenGL e.g. glLoadMatrixf(m.get_raw_data());
