Detailed Description
template<class Scalar>
class ACG::SceneGraph::ACG::Matrix4x4T< Scalar >
Simple 4x4 Matrix. Inherited by GLMatrix.
Definition at line 95 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 110 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());
