Some materials, such as coffee, milk, or marble, have a soft translucent aspect because of subsurface scattering. Light enters them and gets scattered several times before leaving in a different place. A full representation of subsurface-scattering effects in illumination simulation is computationally expensive. The main difficulty comes from multiple scattering events. The high number of events increases...
This paper presents RCS predicting software based on PO and PTD method for the surface and edge integral in the computation of RCS for large and complex obstacle. An adaptive subdivision scheme, which is depending on the situation of Incident Shadowing, Reflection Shadowing, Scattering Shadowing and Multiple Reflections, is developed.
