Surface: Lighting

• Face - Specify method for lighting surface. (FaceLighting)
• No shading (none) - Lights do not affect the surface.
• Faceted (flat) - Uniform lighting across each face of surface.
• Rounded (gouraud) - Linear interpolation of lighting calculated at vertices.
• Smoother rounded (phong) - Interpolate vertex normals across faces. Produces smoothest results.

See Selecting a Lighting Method for examples of these lighting methods.

• Edge - Specify method for lighting surface edges. (EdgeLighting)
• No shading (none) - Lights do not affect the edges of the surface.
• Faceted (flat) - The lighting effect is uniform across each face edge.
• Rounded (gouraud) - Linear interpolation of edge lighting calculated at vertices.
• Smoother rounded (phong) - Interpolate vertex normals across face edge. Produces smoothest results and uses Zbuffer renderer.
• Material - Change the reflectance characteristics of the surface.
• Shiny - High specular reflectance relative the diffuse and ambient light. Color of the specular light depends only on the color of the light source.
• Dull - Surface reflects more diffuse light, has no specular highlights, and the color of the reflected light depends only on the light source.
• Metal - Surface has a very high specular reflectance, very low ambient and diffuse reflectance. The color of the reflected light depends on both the color of the light source and the color of the surface.
• Default - Sets the ambient, diffuse, and specular components of the reflected light to the default values.
• Custom material... - Set individual values for lighting properties. See Properties that Affect Lighting for a description of lighting properties.

See Reflectance Characteristics of Graphics Objects for illustrations of lighting characteristics.

• Back face - Lighting of the side of surfaces whose surface normals face away from camera. (BackFaceLighting)
• Unlit - Back face of surface is not lit.
• Lit - Back of surface is lit without reversing normals.
• Reverse lit - Light the back face of the surface to make it look natural.

See Back Face Lighting for illustrations showing the effect of the settings.
