▪ Recall the names of objects you modeled-Plane, Enemy, and
Player. Listing 4-9 contains the block of data for Plane object.
Perl parser stores object names (for example, “Plane”, “Enemy”)
and uses them to read the material file to get the material colors.
So, corresponding to the Plane object, it stores white col-
or—indicated as "Kd 1.000000 1.000000 1.000000"
(RGB format) in Listing 4-10 .
