Desired Properties of Solid Modeling Systems A. Domain system can represent all objects desired and perform all operations desired. B. Closure operations on valid objects produce valid objects. C. Unambiguous one representation defines one object. D. Validity only valid objects are stored. E. Creation easy to create new objects.
Solid Modeling. This is a method which is adapted to create 3D geometry in computer graphics. Normally, the 3D geometries are created using 3 approaches: 1. Wireframe Modeling 2. Surface Modeling 3. Solid Modeling In wireframe modelling, the model is created by making use of set of lines or wires and hence the name wireframe modelling. Solid Modeling The de facto standard for CAD since 1987 BReps integrated into CAGD surfaces analytic surfaces boolean modeling Models are defined by their boundaries Topological and geometric integrity constraints are enforced for the boundaries Faces meet at solid modeling in computer graphics pdf In particular, we describe the solid modeler Minerva, implemented by computer graphics students and currently used as a didactic tool in our graphics course, which allows students to experiment with affine transformations, and to view models, structure definitions, surface equations, and solid operations.
Introduction to Solid Modeling Hongxin Zhang and Jieqing Feng State Key Lab of CAD& CG Zhejiang University. State Key Lab of CAD& CG 2 Manifold Solid Modeling The surface of a solid is 2D manifold 2D manifold For each point x on the surface, there exists an solid modeling in computer graphics pdf also play a crucial role in solid modeling, since they determine the overall usability of the modeler and impact the users productivity. There have always been strong symbiotic links and overlaps between the solid modeling community and the computer graphics community. The first aim of this paper is to show the influence that graphics methods have had on the research activities carried out in solid modeling at the University La Sapienza.
