Abstract :
Ray tracing is one of the most popular and powerful image synthesis technique for creating photo-realistic images. In this research, we focus on the time critical application of ray tracing in the XPATCH software for high-resolution radar simulation and detection. Of particular interest to us is the ray/box intersection algorithm employed in the XPATCH ray tracer for achieving faster execution time. The ray/box algorithm is used to determine whether a ray hits or misses the target enclosed in a rectangular bounded volume
