yeah, SGE is a nice kit of many of these tools. although some of
the algorithms are a bit rough. (ie, i think i could write a python
line renderer that is quicker than SGE's)

if you want to get your feet into Numeric Python, i believe
you could write a pixel level collision detection in python
that would be quick enough for general use. (although a C
version would be quicker)

if you just need something like this that is quick and dirty
you can probably get by with some good Numeric python code.
if you need something highly tuned, than a C extension will
be the best bet.
