This paper is devoted to the elaboration of spatial indexing methods implemented by means of decomposition technique. Special attention is given to decomposition based on regular octrees, which is known to provide efficient solution for collision detection and spatial query problem and being applicable not only to sets of point data, but also to spatially extended objects. Based on probabilistic analysis, complexity estimations are evaluated for model set of data. They generalize previous results and serve as theoretical background to wide practical application of discussed methods.
