      The approaches are considered to the visualization of the results of 3-D gas dynamics computations with heat conduction on distributed-memory parallel computers. The complexity of this problem is on the one hand in the representation of the function of three variables and on the other hand in the processing implementation of the functions distributed on several compute nodes.
      To analyze the functions of one variable NORS system is used, assembling a problem database using compression algorithms. To analyze the functions of two and three variables the programs were developed for assembling a file in a specialized format.
      A method is presented of data output from a specific part of a 3-D problem using information, only located on the surface of the indicated part, that results in a major saving of the main memory. Principles and algorithms stated in this paper are used in two 3-D complexes.
