A system for calculating orthographic views of three-dimensional objects from a confocal microscope has been implemented in a high-level language. It is used on a regular basis in a number of projects and on different computers. The system enables the user to filter the original data and make a selection of which points and parts of the objects to show in a projective view. The information to be shown is coded in a compact format that is well suited for projection calculations. Several display principles were implemented that enhance different aspects of the objects.
