virtual void Impala::Visualization::Plot::Similarity::Draw ( Plot * plot ) [inline, virtual]

this function calls all opengl statements to draw the plottable all scaling, translation and raotation should be done before this function is called

Todo:: decide what coordinate system to draw in, for now assume [-1..1] in all dimensions

Implements Impala::Visualization::Plot::Plottable.
