Skeletal Animation System

With a skeletal animation system, the mesh used for animating is not the outer skin of the model, with hundreds of thousands of nodes and polygons. Instead, a secondary mesh is used, which is far smaller. This mesh is a skeleton made up of bones ? simple lines connected by vertexes only where a joint would be.

The vertices of the larger model mesh wrapped round the bones, are tied to the bones themselves. For example, the mesh of an avatar?s left forearm in model space, is normalised to the origin of the bone mesh for the left forearm.

In this manner, when you animate the left bone forearm, all the mesh nodes in the left forearm stay in position relative to one another and move with the skeletal mesh. This is a tremendous workload saving, as it does not matter how complex the left forearm is, everything moves together.

One of those rarest of rare books: An animation tome that is not tied down to a specific package. Instead, expect a hefty dose of mathematics, as the author leads you through a variety of animation techniques, both 2D and 3D, from a formulae and expression based perspective.





Timing for Animation by this pair of authors, is back in print. This book, over 20 years old, was and still is the definitive tome for animation. Whether drawn sculpted or CGI, making something move realistically is all about timing. Timing first, second, and last. When to move, when not to move, what to move, and how much to move.

Large Image Display: Prosthetic Jaw Hinging
One of the most important aspects when working with any skeletal system, is the joint where bones connect. If you don't get this area right, then bone will grind against prosthesis, and the bone is likely to take critical damage first. You inflame a joint, that did not have a problem in the first place, and spread further complications throughout the body.



There always seems to be an artificial disconnect between the skillset necessary to draw in 2D and that necessary to animate with CGI. Many books treat it as if you have to unlearn all you know from one, to learn the other, even when that is clearly not the case. This tome shows why it is not.





This tome is, as the4 title suggests, more of an overview for the subject than a detailed how-to. It covers everything from the very basics of computerised model animation, right through rigging and boning, on to timing and lighting ? but it does so without going into painstaking detail on any one topic.





This book is an animation expert's attempt to ?dump his kit? as the author puts it, and share with others the fundamentals of animation that are not generally taught outside of industry practice, and always were taught behind closed doors.





Much of the book is understandably dedicated to cinematography and animation using theatric props. However, even these sections provide insight on how to create an interactive 3D area that achieves dramatic effect almost effortlessly for those entering it, or different approaches to creating a winged avian, that the mind of a visitor will still process as a graceful bird.
