GPU-accelerated Hausdorff distance computation between dynamic deformable NURBS surfaces

► GPU algorithm to compute directed Hausdorff distance between NURBS surfaces. ► GPU bounding-box hierarchy traversal with selective culling of surface sub-patches. ► Novel culling tests to cull bounding-box pairs that do not contribute to HD. ► Tight range for the HD and the surface locations where the HD is within this bound. ► Interactive computation of the HD between dynamic deformable surface models.
