Abstract [en]

Technical visualization is becoming more and more important to product development. If other departments in the company can use the engineer’s 3D models it leads to shorter product development times so the product comes out on the market earlier. This job treats different techniques that can be used for technical visualization e.g. 3D viewers and computer made animations, and the software used to create animation scripts and to compress movies. Important areas in technical visualization are the ability to successfully convert files from one format to other file formats, the performance of the computer hardware you use and the codec you use to compress movies with. Among the wide range of software for visualization some of the more prominent in their category were compared against each other. These are: Viewers VisView I-DEAS WebAccess 3D View SolidView Animation Maya Unlimited Vislab 3D Studio Max Compositing Premiere Maya Fusion For more advanced animation purposes Maya Unlimited is a good alternative, it has a nice interface and very powerful features. Vislab is a perfect alternative if you quickly and easily want to animate basic motions of a product. A low price alternative to Maya is 3D Studio Max that has lots of good features such as ray tracing and inverse kinematics, but are not as intuitive to use and not as powerful as Maya. For video compression of animations MPEG is the best solution. It combines high compression ratios with excellent video quality and can easily be decoded on a new standard computer. MJPEG is an alternative but the files are up to 8 times larger at equal quality levels and need special hardware to decompress. For the 3D viewers it’s more difficult to say that one is better than the other because they have different functions and capabilities. The viewer in this thesis that could handle the largest assemblies is VisView. That makes it perfect to overview the structure of complex constructions. One thing that is clear about the use of viewers is that a faster graphic card always improves the performance, and with VisView and hardware accelerated graphic card you can view assemblies with thousands of parts and rotate them in realtime.
