Some aspects of engineering visualization will be discussed. Among them: - an OpenGL based tool for visualization and real-time verification of the postprocessing stage in multigrid computational environment; - a new effective "cutting" method of creating contour lines based on irregularly spaced data; - particle system approach for physically realistic simulation of the elastic body. Some concepts of the new meshless Multipoint FDM will be presented also. The multipoint approach is based on raising the order of approximation of the unknown function. This method has been developed in order to improve the solution precision of the differential equations.
