Chapter 11: Alien Plant Joint Setup in Blender
In Chapter 3, Let's Sculpt an Alien Plant, you learned how to model and texture the Alien Plant. Now it's time for us to prepare it for animation and to finally give it some life. Most 3D software offers many different ways to animate models. Among these, two are the most common.
The first way to animate a 3D model is by directly moving, rotating, and/or scaling it. This method is best suited for simple animations involving a rigid model. The second method uses a skeleton (sometimes called an armature) that is linked to the structure of the model.
Unless it's a very simple animation, the animation is normally better done using skeletons. The skeletons of 3D models are made up of bones. Just as bones in a real skeleton define the overall shape and mobility of a person, the bones of a 3D model skeleton correspond to the underlying structure, therefore defining which parts of the model can move in animations.
