The bones tool is an inverse kinematics tool.
“Inverse kinematics is the process of determining the parameters of a jointed flexible object (a kinematic chain) in order to achieve a desired pose. Inverse kinematics is a type of motion planning. Inverse kinematics are also relevant to game programming and 3D animation, where a common use is making sure game characters connect physically to the world, such as feet landing firmly on top of terrain.” (Wikipedia, retrieved 15:41, 27 November 2008 (UTC)).
“The characters in a game have skeletons. Similar to our own skeleton, this is a hidden series of objects that connect with and move in relation to each other. Using a technique called parenting, a target object (the child) is assigned to another object (the parent). Every time the parent object moves, the child object will follow according to the attributes assigned to it. A complete hierarchy can be created with objects that have children and parents [...] Once the skeleton is created and all of the parenting controls put in place, the character is animated. Probably the most popular method of character animation relies on inverse kinematics. This technique moves the child object to where the animator wants it, causing the parent object and all other attached objects to follow.]” (How stuff works, retrieved 15:41, 27 November 2008 (UTC)).
Adding armatures to shapes
- Create a new layer
- Draw a shape or a simple drawing in object mode. Make sure to finish the drawing, later you only can adjust its shape.
- Add a bone
- Select the bone tool from the tool panel
- Click inside the shape and drag a bone
- Click at the end point of a bone an drag again
- etc.
- Kill bones
- Adjust
- Use the subselection tool to move
Armatures with symbol instances
= Adjust properties
Select a bone and play with the options in the properties panel
- Joint Constraints
Joint constraints are rotational constraints on the joints of an artificial bone system
