Parsing Objects for OpenGL ES

Now, we demonstrate the use of a Perl ( .obj ) parser to parse the triangulated mesh
data in .obj files. This parser is still in its early stages (it does not support tex-
tures for objects), but it has sufficient functionality to collect the following data from
.obj (and .mtl ) files:

▪ It can collect basic data about objects, such as names and materi-
als.
▪ Listing 4-9 contains a few lines from the beginning of the file
tankFence5.obj , whereas Listing 4-10 contains a few lines
from the file tankFence5.mtl (you exported these files using
tankFence5.blend file).
