SpecularCoefficient

Reflection of ambient light (= 0: light is completely absorbed)

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Type SpecularCoefficient defines the reflection of ambient light on shape surfaces. If value = 0, the light is completely absorbed. Often, 0.7 is a reasonable value. It might be that from some viewing directions, a body is no longer visible, if the SpecularCoefficient value is too high. In the following image, the different values of SpecularCoefficient are shown for a cylinder:
