! provides a number of ways to define surfaces and to bind these surfaces to objects. The most straight-forward method of surface specification is to simply list the surface properties to be used. *************** *** 179,190 **** is used to give the primitive its appearance.
An object that has no surface bound to it is assigned a default surface ! that give an object the appearance of white plastic.
! The first ! and most direct way to bind a surface to a primitive ! is by specifying the surface to be bound to ! the primitive when it is instantiated. This is accomplished by inserting a list of surface attributes or a surface name after the primitive's type keyword and before the actual primitive data. — 186,197 —- is used to give the primitive its appearance.
