Reflections At Room Boundaries In Computer Simulation Programs Based On Ray-tracing

摘要

There are several methods to model scattering with ray-tracing procedures. The secondary sources method as described has basically a good energy distribution for a single order reflection from a flat panel if some scattering is applied (in this case 0.3). Other methods as shown in figure 3 are less accurate for the prediction of a one order reflection from a specific surface. Due to their non-expanding number of rays, they are suitable for the ..reverberation tail" of an echogram.
