AN EFFECTIVE CONTOUR PLOTTING METHOD FOR PRESENTATION OF THE POSTPROCESSED RESULTS
Irena Jaworska · 2006
The paper presents a new method of creating contour lines based on irregularly spaced data. The analysis has been focused on contour plots as an useful tool of visualization and real-time verification of the postprocessing stage in multigrid computational environment. A new effective contouring concept has been introduced and developed to satisfy this objective. The presented approach is based on the OpenGL. research. Numerous graphical modelers and visualization software are available. However, many of these programs have not been designed to deal with the iterative algorithms and do not allow for instant visualization of computation progress, and support for effective mesh modification during computation. Taking into account these requirements, a new advanced graphical tool has been designed particularly to be used with the multigrid mesh generator. Given geometry of the considered domain is used to prepare an initial mesh, which is relatively coarse, and to establish the base for the adaptative procedure. Depending on the solution method, each mesh has to contain
