Applying Properties

Bulk Scattering Standard Expert

Bulk scatter is scatter caused by particles and inclusions within a material. A bulk scattering property works together with an object's material property. (See the Technical Reference page 7.54 for more details).

FIGURE 4.3 - The Apply Properties Dialog Box - Bulk Scattering tab

Bulk Scatter properties are applied by selecting Define|Apply Properties|Bulk Scattering as shown in Figure 4.3 and edited by selecting

Define|Edit Property Data|Bulk Scatter Properties. A simple example, shown in Figure 4.4 on the left, uses a block of Schott BK7, 1 mm on each side. A single ray, shown in red, is incident at 45 degrees on the front of the block. It is then reflected via total internal reflection from one side, and finally refracts through the back surface. The blue rays denote rays resulting from Fresnel reflections.
