Restenosis

Development Aid and Ripeness in Context,We describe a new approach for geometric shape design which his centered around a 2D and 3D geometric constraint solver. This approach enables so-called non-history based modeling providing more flexibility to the designer. The modeler combines geometric and topological constraints, direct manipulation, sketching and Boolean set operations.

POINT

Results and hypotheses assessment,We have developed a formalism to simplify the expression of 3D constraints and their solving. Our formalism makes a strong distinction between metric and projective properties. We represent points, lines and planes in projective space by tensors and use Cayley’s algebra, with the . and . operators, to express projective properties.
