Figure 12From: Proposition and evaluation of a collision detection method for real time surgery simulation of opening a brain fissureCollision detection in situation both sides of a spatula contact. (a) A spatula model is inserted into V-shape valley. (b) A soft tissue is deformed by both sides of the spatula. (c) A spatula model rotates in U-shape model. (d) Each side of the spatula model contacts the soft tissue model and gives enforced displacements.Back to article page
