Well shoot.  Here's one last effort.  I have a mac and I just encoded it in the
mpeg a and b formats with quicktime, so if anyone with a mac knows how to save
these movies in a format that works, PLEASE reply.

Windows Media player says it doesn't have the codec. maybe I should reinstall it
or something.

Nice stuff.  A bit bent-legged maybe.  The motion looks real good to me.
Since you mentioned the toes I'm guessing you inverse-K from those on up
through the legs and hips?  Would it hop okay?

Impressive walk cycle!

I'm working with IK myself and I'm always looking for inspiration.
I'd appreciate if you could explain how you move the feet around. Do you use
splines for the position of the feet? And how do you control how much the
feet point upwards/downwards - another spline?
And what do you mean when you say that the toe detects the ground? Do you
use trace?

If you're interested, you can see my own experiments on this page:

Same here and I just finished installing every codex I could get my mits on
:( It wants to reconnect for the codex, too (after I'd just disconnected,
damnit)

Using the core of your ikleg macro that you posted for me a while ago, I just
added in support for a foot that is always perpendicular to the vector from the
ankle to the hip.  Next, I added in a rotation that rotates the foot before it
is transformed.  I just used the vectors from the matrix transformation to have
it figure out a toe point and basically raise the foot if the y-coord is below
a defined floor level.  As for the motion, I just used my own macro for
motion.  I'll post it in the binaries.scene-files group.
