WebThis paper presents a quantitative evaluation of the accuracy of different sphere-tree construction methods when they are used in deformable bodies. The methods evaluated are Grid (an extension of octrees), Hubbard, Adaptive Medial Axis and Spawn. We also present a new approach to update the sphere-tree hierarchy that ensures lower loss of ... WebThe nodes of the octree are finally used to construct a sphere-tree by creating a sphere that contains each of the "solid" nodes, i.e. nodes that represent part of the object. Our …
