We have invented a new ray traversal scheme that is especially suitable for dynamically changing objects during image generation with ray tracing. This algorithm has recently been introduced for walkthrough [Mortensen, et al. 2004], and it compared favourably with the leading algorithm in the field, Coherent Ray Tracing [Wald et al., 2001], at least in the case of non-parallel single ray processing. Here we only concentrate on dynamic changes to objects. Our approach supports dynamic object changes in a very simple way since the major operation in the algorithm is only 2D polygon rasterisation at very low resolutions. At the moment our implementation is single processor, and does not make use of the graphics hardware, nevertheless the results are promising.
