A rope is a link from a leaf–face to its neighbour–node. Using ropes in ray–traversal algorithm we can avoid most of the traversal steps of interior nodes of the BSP tree. 1Objectsare orderedby the xcoordinatein the case of a splittingplane perpendicularto the axis; similarly for the othertwoorientationsofthesplittingplane RopeConstructionAlgorithm

Key words: spatial subdivision, BSP tree, spatial data structures, rope trees, ray tracing. 1 Introduction Ray tracing is a well--known rendering technique for producing realistic images that simulates well specular surfaces. The main drawback of this algorithm is its rather big computational complexity, that disallows its interactive use.

Abstract In this paper, we present a method for nding the nearest ray-object intersection. Our method uses binary space subdivision. To accelerate the tree traversal time, we use the technique called rope trees. A comparision of results between traversing BSP tree with and without rope trees is included at the end of this paper.

In this paper, we show that none of these assumptions is com-pletely true, and that a building a BSP based ray tracer—when using

We present a new method for ray tracing acceleration by modification of current spatial data structures. We augment a spatial hierarchy such as kd-tree with sparsely distributed bounding boxes that are linked from bottom to top. The augmented data structures can be viewed as a hybrid between kd-trees and uniform grids.
