Abstract
Majority of the computer graphics applications is based on the meshes constructed from the finite elements. Apriori constructed meshes from the fixed position inner nodes can lead to malformed meshes and stability problems. Relaxation method can correct this ill-shaped structure. A physically based relaxation method is presented which can be a basis for a different methods of analysis and renderings. Radiosity is an example of such application where one can gain speed/complexity tradeoff with use of hierarchy and wavelet transform in form-factor computations. Wavelets can be used for a basis of multi-resolution analysis. Standard application of wavelet radiosity is extended from underlying function space of radiosity to geometry. This multi-resolution approach can be also applied to arious types of scientific visualizations.
The significance of physical laws in designing technical systems has been acknowledged for a long time. They are also intensively used in the analysis of designed technical systems. In spite of their significance, though, there are insufficient tools to allow explicit use of physical laws and their chaining with regards to designing technical systems. The purpose of the project is to develope an algorithm and represent results obtained using software which is based on the algorithm. The problem of formalising the transition from basic schematics, which represent a complementary part of physical laws, to a schematic of a future technical system is also indicated. At present, this transition is performed informally by a design engineer and executed without major problems. However, there is a desire to formalise this transition, because it would enable development of another module of computer-aided conceptual design software. In addition, the advantages of formal models in general could be exploited.
The small and midsize companies are under pressure of non-stop costs reduction. Applying of product data integration could significantly improve the companies competitiveness. Most companies can not effort big investments into information systems and the employees do not have necessary knowledge. We intend to prepare reference models for PDM systems in a mechanical engineering, which will help to define actual needs inside the enterprise. We are concentrated, first of all, into development/design phase. The models will be the results of applying PDM system into different enterprises.
