Description
Summary:A new acceleration technique for the ray tracing algorithm was presented in this paper. Instead of reducing the number of intersection tests, our proposed method finds the solid angles around the transmitter that transport electromagnetic power to the receiver. Then, high-resolution rays are sent out only in these solid angles and the procedure continues iteratively. Since a few rays are traced in each iteration, high resolution can be achieved within acceptable amount of time.
