Graphic Techniques and Fundamental of the Next Generation CAD/E System
Computer-Aided Design also known as CAD has become very popular since the early 1990s. CAD drawings are designed to help engineer physically visualize the solutions for our everyday problems. We are going to look over some the fundamentals of the next generation CAD and engineer systems, as well as some new techniques and methods to construct a more detailed and advanced graphics with CAD softwares.

The first article I reviewed is a study conducted by Deng and Ma on the issue of interpolation of loop subdivision surfaces. Deng and Ma argued that the most efficient way to create a detailed graphic is utilizing the mathematics behind the concept of interpolation of loop subdivision, to create this extreme detailed graphic. Deng and Ma used complex graphics such horse, a knot and an ant to compare the difference using different concepts, it was obviously using the interpolation of loop subdivision was more clear and detailed. Deng and Ma claim by using their researched method, could help the future CAD and Engineer systems to give a much more realistic view of the concept and prototypes, and making the digital media look more realistic to real life (Deng, Ma, 2012).

The second article that I reviewed was a study conducted by RJ Cripps and Greg Mullineux on the topic of how to effectively constructing 3D motions from curvature and torsion. Cripps and Mullineux mentioned some of the problem with in to construct a free form 3D motion. Cripps and Mullineux claim that use Bezier and B-spline segments or patches can restrict the range of forms that can be achieved, and use of parameters which have no actual direct geometric significance for the shape itself can lead to many unexpected results. Cripps and Mullineux said the use of point-based representations has emerged recently as a mean for overcoming these drawbacks they described (Cripps, Mullineux 379-387).

The third article focused on how...
