Stumbled on to this. Quite interesting. Have to check it out further. Seems to have some possibilites.

I checked the thread out concerning the walk cycle and thought it was interesting in terms of the maths.

I would be reluctant to illustrate that walk cycle if I was teaching a walk cycle to animators, I might send it to the competition as a friendly jest :D . The examples doesn't explain the hip rotation, infact it only represents one hip.

However that may be due to the fact that the odd linear looking character has been in a tragic accident, its certainly put stick man of his food :(

heres a much more useful one in terms of the mechanics-

And here is a link that helps you consider "attitude"-

Granted the walk cycle shown wouldn't be Useful. I was just interested in the math that was involved. For a convincing walk cycle you'd have to take it from there to a much higher level. It's interesting, but I don't really have time right now to study it further.

Here's another one. I saved the flash file as a reference for some.

Thanks fo rlinks, that Flash stuff is really cool. Here's another trick.

How to add very simple muscle mass fake to the knees of a character,
ok, this is 4 3Dmax, but it should work somewhat for LW as well I think.

That sound pretty interesting with the muscle mass, but the link came up 404.

Oh, it wasn't the full path. Why can't the forums display the whole path.. oh well. Here'sthe link.. :)

I really like that one.....thats a keeper!

There's a link to a little more of the mathematics involved in This walk cycle. I'm always intrigued by the mathematics of this 3D stuff, even though I don't understand some of it. I'm considering that it could be used, at least for some basics, with some type of nodal expression builder, such as Amelie. Or maybe NT could incorporate it into the core somehow. But here's a link to some further detail.

There's even more here. Of birds etc.

Thanks once again for that link, very informative and useful.

I liked the pigeon study very much.

I showed that link you provided to a bunch of students on Friday and they really appreciated it. I had been making them do excercises on walk cycles through pixelation and Stop motion through clay.

Great fun, but showing them links after their efforts made more sense. Spoon feeding them and not getting them a sense appreciation may have been the result otherwise :) .
