View Full Version : New Guerrilla CG Video : The Rotation Problem

 andrewsilke12 December 2008, 06:01 AMHi guys we've got a new video up at The Guerrilla CG Project (http://guerrillacg.org). This one is an overview of 3d rotations, called The Rotation Problem (http://guerrillacg.org/home/3d-rigging/the-rotation-problem). It's the first video that goes into that age old problemcalled gimbal lock. We'll have a follow up video that covers Euler and Gimbal in more detail. We've also opened up the contributor forum to the public and have a new menu section WIP (work in progress) so everyone can see what we're up to. http://www.guerrillacg.org/images/stories/misc/frontPageVideoBanners/rotationProblemFrontPage.jpg (http://guerrillacg.org/home/3d-rigging/the-rotation-problem) Rotations in 3d are not easy to understand. This video examines some of the problems surrounding 3d rotations and briefly explains the two rotation types, Euler and Quaternion. Rotations are only a problem for animators. Euler rotations experience gimbal problems while quaternion rotations lack animation curves. Coming Soon Videos Euler Rotations Explained (and Gimbal Lock) Sub Division Surfaces Bump and Displacement Mapping Overview cheers Andrew Silke www.guerrillacg.org (http://guerrillacg.org)

I just want to tell you that I love your site. Great information! I had to clean out my bookmarks so it wouldn't get lost like all the other links I bookmark.

That was great. I never realized the rotation problem existed. I'm not really an animator, but it's good to know.

These are really great, so perfectly explained. I feel like I've heard lectures hours longer on the same topic and never learned as much.
