We present a new method that utilizes path coherence to accelerate walkthroughs of geometrically complex static scenes. As a prepro- cessing step, our method constructs a BSP-tree that hierarchically partitions the geometric primitives in the scene. In the course of a walkthrough, images of nodes at various levels of the hierarchy are cached for reuse in subsequent frames. A cached image is reused by texture-mapping it onto a single quadrilateral that is drawn in- stead of the geometry contained in the corresponding node. Visual artifacts are kept under control by using an error metric that quan- tifies the discrepancy between the appearance of the geometry con- tained in a node and the cached image. The new method is shown to achieve speedups of an order of magnitude for walkthroughs of a complex outdoor scene, with little or no loss in rendering quality.
