This paper presented some initial attempts and results connected with 3-D modelling of irregularly shaped bodies. The basic data were
taken from the VHD. Some pre-processing end editing tools were developed in order to manage the spatial modelling. The resulting
procedure is quite general and not too complicated. It can also be used in some other areas of medicine. The produced human heart
model can be used for a computer simulation of heat transfer, in the simulation of electrical cardiac signals and in many other medical
applications. The 3-D model can be further improved with the inclusion of more different types of tissue, such as distinctly different
myocardium layers and with some advanced functions for automatic 3-D editing.
