If you're on a UNIX and have pyz80 in your path then execute:

	./compile.sh

To build '3d.dsk', which is the Cobra model spinning and a user
controlled camera. It simply executes the command line:

	pyz80 -I SAMDOS -s himem src/lib3d/3d.z80s

Which should work anywhere that pyz80 works.

See any of the files named 'Manual' in 'Documentation' for an
overview of the library. That document is currently incomplete
in that it lacks data structure descriptions. For now, see the
various source files in the 'src' folder to get that information.

This code has several imperfections from a performance point of
view and does not always represent the approach I would take if
writing it afresh.
