IRIT modeling environment
IRIT is a solid modeling environment that allows one to model basic, primitive based, models using Boolean operations as well as freeform surface's based models. It has several unique features such as strong symbolic computation, support of trivariate volumes and triangular patches, high portability, and numerous unique applications such as surface layout decomposition, metamorphosis of curves and surfaces, and artistic line art drawings of parameteric and implicit forms. Several OS platforms are supported - see page for details.
