| Description | . Acceleration structures used for ray tracing have been designed and optimized for efficient traversal of static scenes. As it becomes feasible to do interactive ray tracing of moving objects, new requirements are posed upon the acceleration structures. Dynamic environments require rapid updates to the acceleration structures. In this paper we propose spatial subdivisions which allow insertion and deletion of objects in constant time at an arbitrary position, allowing scenes to be interactively animated and modified. 1 Introduction Recently, interactive ray tracing has become a reality [8, 9], allowing exploration of scenes rendered with higher quality shading than with traditional interactive rendering algorithms. A high frame-rate is obtained through parallelism, using a multiprocessor shared memory machine. This approach has advantages over hardware accelerated interactive systems in that a software-based ray tracer is more easily modified. One of the problems with interact... |
