Geometry Lab with Mathematica Mathematica Is Used in a Course of Geometric Techniques for Computer Graphics & Cad

An experience of a Geometry Lab based on Mathematica for a Geometry course for Computer Science students, intended to be a basis for later courses in Computer Graphics, CAD and CAGD, is presented. Students combine their knowledge of basic geometry topics like polyhedra, curve and surface generation, aane and perspective transformations, among others, by means of lists manipulation and a clever use of substitution rules to generate apparently complicated geometric scenes in which geometric objects are placed in diierent positions in space. Several examples are ooered, some of them together with their code. The reader can enjoy himself solving the proposed examples and producing new variants.
