Since the Amapi soccer ball movie was such a big hit you knew there
had to be a sequel.
Here it is:

A step by step list and a 6meg movie.
I zipped the movie instead of linking directly to the avi file. Some
people who tried the direct linked Amapi movie had trouble with
Windows Media player trying to get to it. Just download - unzip and
then play it off the hard drive.
Let me know if there are any problems or questions.
One thing to keep in mind is that the ball is not the main point of
all of this (even though soccer balls can be very entertaining). The
focus should be on modeling geometric shapes using different methods
and modelers. Lots of things to learn and transfer to other projects
in doing something that seems difficult but is pretty simple in the
end.
A few notes:
1. It turns out the process was just about the same as it was in
Amapi with the exception of sawing off the corners of the isocahedron
to from the pentagons. More than a few ways to do it, I ended up
using a boolean intersection.
2. Tessellation was not needed to give the ball a nice round shape.
The spherical morph tool (unlike the one in Amapi) adds the extra
facets it needs
3. Naming polygons before you extrude them keeps all the new facets
generated from the extrude within the same naming group. This saves a
good deal of time when trying to divide up the object into shading
domains later on for texturing.
4. As a general rule of thumb booleans are not the best way to build
something... with exceptions.
They work here because both objects are low poly, similar in face
count and intersect each other cleanly. If you work through this you
will notice that the boolean intersection still leaves an extra
vertex on every edge that does belong there. Luckily they do not
cause any real problems on the ball otherwise they would have to go
(using the scissors tool)
