Abstract (in english)
   Space decomposition methods represent an important part of numerical modelling process. Using current methods, creating 3D models is an extremely time-consuming, unreliable, and labour-intensive process. So, when the geometry information is obtained e.g. from computer tomograph or similar devices, i.e. in the form of pixel/voxel grid, it is reasonable to create the space decomposition in the same or similar way. Different raster concept, based on regular hexagonal mesh, is analyzed e.g. in [3]. There are several methods how to decompose 3D space into the set of the same tetrahedra [1], [2], [4]. In the paper the discretization scheme based on Goldberg's one is introduced: we find tetrahedral element which is close to equilateral (regular) one and which can be used as a 3D space filler. Mutual realtionshis betwee voxel decomposition and our approach is presented.
