Tutorial – Rigging the Gyrocopter, Part II


Rigging the Gyrocopter, Part II

Sorry I’m late! Last week was crazy, but here I am with Part II of the tutorial. Video quality is much better this time (720p in fact), and I managed to stay around the 20 minute mark, so check it out to learn how you can use Spline IK to rig things like hoses or ropes or stuff like that.

I first went to the wiki to try to figure out how it worked, but you know the wiki – even though the intention is great it’s always hard to explain things by text. So a big thank you goes to Nathan Vegdahl and his Mammoth Rigging Tutorial, where this subject is very well explained. I haven’t gone through all of it (I skipped around to the parts when Spline IK was dealt with), so you’ll probably see a review post on it soon, but so far it really is a great product. If you want a better explanation of why cyclic dependencies are a bad thing (instead of my attempt in the video – “it does crazy stuff”, I still can’t believe that’s how I summed it up!), go get it!

I hope this was useful to you, and as always, please go ahead and leave any feedback on the comments below!


You can find Part I of the tutorial here.

    Very nice, thank you, didn’t realize the xray worked on other objects (all?), rather than just bones.

    watched it again…
    At 17:40 in the video you grab the end armature (bone?) and move it and the hose follows, good, but why don’t the other two bones move? They got hooks like the first one.
    Wouldn’t it be better to hook the bone on the end of the hose to the socket it fits into on the hyd. Cylinder? Then you wouldn’t have to move the end of hose separately.

      Hi Craig, thanks for watching! The hooked bones need to be moved independently, unless you constrain them to each other. It depends on what you want, fine control over each bone or a more automated movement. Your second question is a good one, I’m not sure it can work that way but it would be a good thing indeed. I really should revisit this rig and maybe do a part III video, Nathan’s new DVD game me a few new ideas to make this work much better.
