Blitz Support : |

Hi,
in the coming semester I have to write a character animation system for a
small student project. I am wondering if I can use Blitz++ ( mainly
TinyVector and TinyMatrix ) for the affine transformations.
1.) Did anybody used Blitz++ with OpenGL or DirectX? Are there any problems
passing a TinyMatrix<float, 4, 4> to one of the APIs?
2.) Does Blitz++ support affine transformations? If not - how shall I
implement the basic transformations ( scale, rotation, translations, ... )
such that they can be concatenated efficently and can be written like below.
E. g.
TinyMatrix<float, 4, 4> transform = translation( 0, 0, -3 ) * rotation_y (
45 ) * translation( 0, 0, 3 );
Can I write wrapper functions to implement the basic transformations or
should I better use the ListInitializer like in the transform example?
3. ) I would be also nice to have support for some geometric objects like
lines, planes, boxes and so on? Would it be a good idea to implement them on
top of Blitz++? E.g.
struct BBox
{
TinyVector3<float, 3> min, max;
}
So the question is if Blitz++ is suited for a task like mine or if should
implement a small math library own my own that suits my needs.
