IN4003 Geometric modelling
Lecturers: Dr. W.F. Bronsvoort, Ir. F.H. Post
Hours and credits: 0/0/0/4 lectures and 56 hours practical work; 6 ECTS.
Material: Reader, sheets and practical manual.
Goal: Geometric modelling, shape description of 3D objects, is a basic discipline of CAD/CAM, computer graphics, robotics and other technical applications. This course covers solid modelling (for 3D solid objects), surface modelling (for 3D freeform surfaces) and feature modelling (to store geometric and related functional information). The goal is to learn about theory, implementation and applications of the modelling approaches mentioned.
Contents: Methods and techniques from solid modelling, surface modelling and feature modelling. The main topics are: spatial data structures, constructive solid geometry, boundary representations, model specification, model conversions, parametric curves and surfaces (Bézier, B-spline, NURBS), polygon and polyhedron meshes, parametric modelling, constraint-based modelling, design with features, feature recognition, feature conversion and collaborative modelling.
Practical work: Programming exercises for geometric problems and exercises with the Pro/Engineer feature modelling system.
Examination: Written examination.
