Some methods for grid data vizualization

M. V. Abakumov


Abstract: A modified method based on the quadtree algorithm for contouring functions of two variables suggested. A method for formalization of zooming, scrolling and printing operations proposed. The way of efficient grid function access and the “quick” area fill method in Win32 considered. A universal structure of the 3D calculation file and realization of high-speed access to such files discussed. A technique of MPEG4 video generation in Win32 described.
