I'm looking for a suitable model based on open source underwater acoustic ray Java ray tracing system. Such packages may be similar with a Gaussian beam (GRAB) integrated acoustic system simulation (CASS), but I prefer to be open source, free or free to modify the model used in the demonstration to an open forum (such as JavaOne).
I need the best model will be based on the environment model, sounding method (also known as seabed topography) and spectrum to provide transmitter ray path modeling Note: multi-path effects (including reflection and refraction) are my main points of interest, and therefore the best package can be used directly.
Is less desirable a standard Java-based ray tracing program package (optical or acoustic), the program may be processed by a variety of velocity of the medium. Another theory is that the refractive index changes in a continuous manner throughout the medium (although its first derivative may not be continuous).

RaPSor project seems to be a Java-based ray tracing simulator. It actually represents a radio propagation simulator, originally developed to support propagation of radio signals, for example, a blind spot for projecting the WiFi coverage area in the building.
Carefully read the use case paper something can be known, it can indeed be a ray tracing, and can be extended to support voice track. I was prompted to blog article refers to the idea of the sound field to figure out the room, but I do not understand why We need to limit the spread in the air.
In addition, it is built using the NetBeans project.
