Learning outcomes

This course aims at providing the student with the tools needed
to master the algorithms and computational methods upon which
many interactive computer graphics applications are based. The
focus is on understanding the theory (geometry, radiometry) and
the computational issues (algorithms, programming) that lie
behind computer generated images.
