Contents Materials » Optical PropertiesPrint page Optical Properties Optical Properties allow to determine how light rays behave and interact with the materials applied on geometries. This section contains the following topics:Optical Properties Overview Optical Properties define how light rays interact with geometries in the CAD. Objects have volume and surface optical properties. Non-Homogeneous MaterialNon-homogeneous material is a material to apply to a body for which the refractive index and the absorption can vary in space.Surface State PluginOptical Properties CreationOptical Properties can be applied to solids or faces. VOP on SurfaceVOP on Surface allows Speos to simulate non-closed bodies with volume properties.Optical Properties ManagementThis section helps you manage and share materials in a same project or between projects.Locate Material ToolThe Locate Material tool allows you to analyze the scene and identify on which geometries the materials are applied and on which geometries they are missing. « MaterialsOptical Properties Overview »
