Computer graphics defined

To define the structure of a molecule in a precise manner then, we must create a list (the order is not important) of atomic coordinates Xj, yj, Zj (and here the order is important). A molecular structure becomes a set of ordered triples Xj, yj, Zj, one for every atom. This is imminently suitable not only for translation into a visual representation, but for manipulation and analysis in a computer, and presentation on the screen of a computer graphics workstation in any number of manifestations. 

The most general device driver interface is the Computer Graphics Interface (CGI, called "VDI" in Europe) CGI will standardize device drivers, making all graphics devices appear to be identical by defining an interface to a virtual (ideal) device This standard interface protocol is converted to the actual form for a real device in the host (with a device driver) or in the graphics device itself. 

Surface (3D) Reconstruction Surface reconstruction from point clouds is fundamental in many applications. Using the raw point clouds or volumetric data acquired from an unknown surface, an approximation of the surface can be constructed and used to compare it with CAD models or for smface-based automated programming. Reconstruction methods can be classified into two types the computational geometry approach focuses on the piecewise-linear interpolation of unorganised points and defines the surface as a carefiilly chosen sub-set of the Delaunay triangulation in a Cartesian coordinate system, and the computer graphics...
