Rigging in 3D animation
Download as PPTX, PDF1 like1,610 views
Rigging is an essential process in animation where custom controllers are attached to the skeletal structure of characters, enabling smoother movements and realistic animations. It involves creating a hierarchy of bones and joints, with various types of rigging for key body parts like the spine, arms, and fingers, which express characters' emotions and motions. While rigging enhances the animation's quality and efficiency, it can be time-consuming and limiting in terms of character positioning.

- 2. What? What is it? Rigging is a fundamental part of the animation, where various custom controllers are attached to each skeletal body part. These controllers and manipulators usually consist of simple joints, locators, selection handles, spine curves, or even an independent graphical user interface for control selection Extra points.. • Connecting a rig to a model is a process called binding • The process of manually doing this for each character and object in a project makes the pipeline of character animation more time-consuming, difficult and problematic • A good character rig is created according to the needs and principle requirements of the characters motions Conclusi on Clay Model example s Why?

- 4. What? Types of Rigging Fingers 3 Root 2 Spine 1 The development of the system starts from torso or spine. Spine is the most crucial part as it holds all the different body parts together and thus becomes the origin of their motion. The root controller manipulates the entire upper body portion of a character. The fingers convey just as much emotion and intensity as the face expressions do. Hand gestures are often regarded as the punctuation of a character’s body language. Conclusi on Clay Model example s Why? A&D 4
- 5. What? Types of Rigging Arm Rigging 5 Head & Neck 4 They are key body parts in rigging as their relationship with each other expresses the attitude of the character. The distance & angle of joints need to be taken into consideration. Conclusi on Clay Model example s Why? A&D 5
- 6. What? Clay Model Clay Model 1. Modeling clay is any of a group of malleable substances used in building and sculpting. 2. There are different kinds of clays available for instance; Ceramic Clay, Oil- based Clay, Polymer Clay, Paper Clay. 3. To make these models into motion, clay models are transformed into marionettes( puppets worked by strings or under control). This is where 3D rigging comes into process. 4. 3D rigging creates a skeleton for a 3D model- all the bones and joints inside a character gives an animation software vertices which it can recognize. 5. Each bone is assigned properties and constraints. 6. It gets even more technical when you start animating facial expressions. Using programs such as Unity and Blender, animators can use drivers, morphs, kinematics, and weight painting, among other tools, Conclusi onexample s Why? A&D 6

- 13. What? A&D Always Remember! 1. Keep it Simple 2. Quick to pose – consistent 3. Essential to know what the director want from the character and what the story board is 4. Lock anything you don’t need to animate with (prevent potential rig damage) 5. Clean hierarchy under one main node 6. Layered deformation system 7. Give animator control over some deformations 8. Better communication between animator and rigger Conclusi on Clay Model example s Why? 13
- 14. What? A&D -Rigging makes animation faster and smoother without difficulties -This technique simplifies the animation process and improves production efficiency. Once rigged with skeletal bones, any 3D object can be controlled and distorted as needed. -In the entertainment industry rigging is a major step in the standard way of animating characters. Achieving smooth and complex animations is entirely dependent on the quality of the rigging phase in the animation pipeline. Advantages Conclusi on Clay Model example s Why? 14
- 15. What? A&D -Time Consuming: It can take some time to prepare and the character is limited by the rig. That means, you can’t put the object in any position you can imagine, only those you can achieve with the rig. -Not the fastest way to animate: Another disadvantage is that it’s not the fastest way to animate, because if you want to move his hand, then you need to rotate the shoulder, then the arm, then the forearm until you get the hand to the place you need. -Restrictions: Another disadvantage is that you have limits, you can only do what the Rig allows you to. You can’t move the character into any position you can imagine, but only into those allowed by the rig. Disadvantages Conclusi on Clay Model example s Why? 15
- 16. What? A&D Controller PropertiesTo move and rotate the different part of the character around for themselves. Animators take help of variety of shapes to identify the function of the control. These are the control types we'll encounter in this rig: 1. Spheres serve as rotate controls. 2. Diamonds serve as translate and rotate controls. 3. Cubes serve as translate controls. 4. Trapezoids serve as joint controls. Some controls affect the position and rotation of other controls. This is because the controls are arranged in a hierarchy. For example, when you manipulate Topcon (the highest control in the hierarchy), all the other controls move and rotate with it. In a hierarchy of objects, an object directly above another object is called a parent of that other object, while an object directly below another object is called a child of that object.

A&D Conclusi on Conclusion Clay Model example s Why? • Rigging is placing bones in order to support a model with a skeleton like structure. • It works in a hierarchy. • It is done at the preproduction stage. • There are 5 types of Rigging. • All the bones are attached to the parent bone. • Rigging helps in getting smooth movements making the animation look more realistic. • Some of the Software's used for rigging are: i.
