Lecture 1 cad [compatibility mode]

  1. 1. Introduc ction toCAD/ CAM & CIM
  2. 2. CAD: It can be defined as the use of computersystems to assist in the creation, modification, y e , ,analysis or optimisation of a designCAM: It can be defined as the use of computersystems to plan, manage and control the y p , goperations of a manufacturing plant throughdirect or indirect compputer interface with the pplants production resour rces
  3. 3. A CIM architecture is an information systemsstructure that enables industrial enterprises sintegrate information and business processes It daccomplishes this first by establishing the directionintegration will take; and second, by defining theinterfaces between the us sers and the providers ofthis integration function function.

  30. 30. The B iTh Basics Computer graphics: genera ating 2D images of a 3D world represented in a comp puter. Main tasks: modeling: (shape) creating an representing the geometry nd of objects in the 3D world rendering: (light, perspective) generating 2D images of the objects animation: (movement) describing how objects change in time
  31. 31. Why St d CWh Study Comput G ter t Graphics? hi ? Graphics I like to see what I’m doing I like to show people what I’m doing Im Graphics is interesting Involves simulation, AI, algorit s, architecture… o es s u at o , , a go t thms, a c tectu e I’ll never get an Oscar for m acting my But maybe I’ll get one for my C special effects CG Graphics is fun
