| Abstract |
Boundary element (BE) analysis is well known as a tool for assessing the stiffness and
strength of engineering components, but, along with finite element (FE) techniques, it is also finding
new applications as a means of simulating the behaviour of deformable objects within virtual reality
simulations since it exploits precisely the same kind of surface-only definition used for visual
rendering of three-dimensional solid objects. This paper briefly reviews existing applications of BE
and FE within virtual reality, and describes recent work on the BE-based simulation of aspects of
surgical operations on the brain, making use of commercial hand-held force-feedback interfaces
(haptic devices) to measure the positions of the virtual surgical tools and provide tactile feedback to
the user. The paper presents an overview of the project then concentrates on recent developments,
including the incorporation of simulated tumours in the virtual brain. |
