An ophthalmoscope simulator for simulation and a method for simulation of the handling of an ophthalmoscope, having a support that can be attached to a head of an observer, at least one first imaging display disposed on said support, wherein the display can be placed in front of an eye of the observer for displaying a virtual reality, an ophthalmoscope dummy that can be supported by one hand of the observer, a position recognition system for determining the spatial position and/or orientation of the support and of the ophthalmoscope dummy and a computer for displaying an image of an environment, a patient head and/or at least a portion of the ophthalmoscope dummy on the display. In particular, a patient head dummy is provided that comprises at least one peripheral surface with a patient eye position defined therein, wherein the spatial position and/or orientation of the patient head dummy can be determined and displayed by way of the position recognition system and that in addition to or alternative to the ophthalmoscope dummy an image portion can be added to the image displayed to the observer, wherein the image portion represents a virtual retina as could selectively appear to the observer, taking into account the spatial position of the support, the ophthalmoscope dummy and the patient head dummy.

An improvement to a voxel-based system to permit rapidly deforming volumetric objects made up of inhomogeneous material provides different material constraints assigned to different elements, with the constraints of a link between two neighboring elements being calculated from contributions of the two affected elements. The order in which neighbors of moved element are considered for a move determines where in the body information is propagated first. The processing order can therefore be used to model different direction-dependent propagation speeds in the material.
