dc.description.abstractRegular grid spatial subdivision is frequently used for fast ray tracing of scanned models. Scanned models feature regular sized primitives, with a regular spatial distribution. Grids have worse performance, than other subdivision techniques, for irregular models without these characteristics. We propose a method to improve the performance of grids for rendering irregular scenes by allowing the individual placement of grid split planes: the rectilinear grid. We describe how to construct and traverse a rectilinear grid. To exploit cache memory in modern processors compression is used for the split plane and grid cell data. We demonstrate in a series of tests that the method has faster ray tracing rendering performance than a compressed regular grid of similar dimensions.en
