Thanks for the reply. I think your suggestion of going binary is one
of the better ones I had considered. Especially because I can avoid
the parseFloat() calls altogether using this method.
As for the quaternion vs axis/angle, I had thought I HAD to translate
them originally (I found out later
Fadden,
Sorry, I missed your reply when I responded to Bart!
I tried to find significant ways that I could avoid allocation, but
the StringTokenizer is the main thing that I'm calling 'new' on and I
didn't see any way to avoid doing that for every line. Your
suggestion of using regexs for a par

Is there a reason to why you use a LineNumberReader? I would instead
use a BufferedReader, that will probably improve your performance.
I don't know anything about the dataformat in the file, but there
probably is a much faster way to parse it than using all those
StringTokenizers (or regexp even
Thanks to everyone for the help on this. As I mentioned, I'm rather
new to Java, so things like StringTokenizer being legacy are news.
Believe it or not the file format uses actual frames instead of
keyframes (hence no timestamp or other indication of time or frames
between each being parsed out)
