Understanding Kinematics Involved in Rigging


You must have watched various animated films, but have you ever wondered about the art and engineering involved in bringing each and every character alive. With 3D animation coming into being, the world of cartoons have gained a new dimension. Innovation has taken this industry to an all new level of perfection. If you just delve into the entire concept you can as well unfold the fact that every animated character is not just a work of pencil strokes and colors. Soon as a modeler completes creation of a character, it is delivered as a 3D mesh, like what you find in sculpted figures.

An insight to rigging

Rigging is essentially the framework behind the making of animated characters. It provides the digital skeleton to a character and is just the same as that of a real skeleton. You will be surprised to know that a rig comprises bones and joints much like real life individuals. They are made in a way such that the animator who is behind the making of animation can bend the limbs and parts of the body to set the model for a desirable pose.

Most interestingly character rig may not necessarily be simple. It can be as complex. Did you know that a simple pose can be created in just a few hours while, the articulated rig will need the animator to devote weeks and sometimes months? The second, is considered keeping a Pixar level feature film in mind. Keep your eyes on the following aspects of rigging and you will find the tricks behind:

Place the skeleton: This is the basic step to the process and this is where the parts and joints are placed in a way resembling that of a real skeleton.

Forward Kinematics:  This is a basic step to rigging and it involves a lot of calculation entailed in the joint movements of a fully completed rigged character. During forward kinematics the rigger has to pay attention to joint movements having impacts on the body parts of the skeleton.

Inverse Kinematics: This is basically a movement which stands just in reverse of forward kinematics. The kinematic is considered while rigging limbs of a character.   IK rig is appropriate to present a character as he climbs up a ladder or something alike. Since, the limbs of the character can be perfectly placed, exactly on the rungs of a ladder, the IK rig makes the process easier for the animator.

Degrees of movements: Rigging involves the use of angles in the movement of a character. Hence, the rig cannot be moved freely as ever. It has to move along an axis.

Squashing and stretching: This is one of the major considerations. It is taken into account when the rig continues a stretch or a squash movement. It gives a realistic motion.

Facial rigging: The facial rig of an animated character will entail the expert on rigging and animation Perth, to efficiently control over facial movements.

Rigging being and essential part of modern animation takes you to higher levels of kinetic depth involved in animated wonders.
