surface surface-name surface-definitionThe surface keyword is used to associate a name with a surface definition (see "PeachPuff" in the example below). Any object that does not have a surface definition associated with it is assigned Rayshade's default surface (a white/grey).
The example below, demonstrates each of the ways to apply surfaces to objects.
