Solid Modelling
Solid modelling involves fundamental techniques essential in engineering, manufacturing, and medical applications. Various methods, including sweep techniques and Boolean operations, allow for the creation of complex geometries. The representation of models through Boundary Representation (B-rep) and Constructive Solid Geometry (CSG) reveal their respective strengths in flexibility and efficiency. The use of pixels and voxels in medical modelling enhances the development of precise anatomical representations, while CAD data exchange standards ensure effective interoperability across various platforms.
