I need two algorithms, both need to be all integer as this is
an assembly language implementation...

[1]  I need an algorithm to simulate a "circle" using CARDINAL splines.
     I already have the cardinal splines up with all the matrix
     manipulation routines, I simply need an algorithm which can
     simulate the proper points of the circle to reproduce it fairly
     accuratly (this is being rendered at 1/1000" resolution)

[2]  I need the preverbeal ellipse algorithm.  This needs to be
     general purpose such that it can be scaled and rotated in
     any axis.  It would be MOST preferable if the above [1]
     algorithm could do this also!

Please e-mail me any suggestions... thanks for your time!
