Figure 6From: Proposition and evaluation of a collision detection method for real time surgery simulation of opening a brain fissureUnrealistic deformation [[26]]. (a) Two groups of collision pairs. If a spatula moves right and penetrate a brain, collision pairs on the right plane are feasible. From only geometrical information, it is difficult to decide which collision pairs should be used as enforced displacements. (b) Given all pairs as displacement, the brain deforms unrealistically.Back to article page
