iClone 4.31 3D Animation Beginner's Guide

By: Mike D McCallum

Overview of this book

Reallusion’s iClone is an animated movie making application that allows hobbyists, machinimators, home-based animators, and professionals to visualize their story or an idea by seeing it in action. Years ago, creating animations and single images would require a team of trained artists to accomplish. Now, iClone real time rending engine empowers its users to instantly view what is loaded into the 3D workspace or preview it as an animation, if you have the precise instructions.The iClone 3D Animation Beginner’s Guide will walk you through the building and animating of a complete scene and several one-off projects. First we create a scene with sky, terrain , water, props and other assets. Then add two characters and manipulate their features and animate their movement. We will also use particles to create the effect of a realistic torch and animate cameras to give different views to the scene. Finally we will see how to quickly import images to enhance the scene with a mountain, barn, and water tank. It will cover some fun stuff such as playing with props, characters, and other scene assets. It will also demonstrate some advanced topics such as screen resolution, formats and codecs but mostly it will deal with doing hands on animation with precise instructions.Starting with a blank project using stock and downloadable assets you will learn to lay out and animate a scene and export that scene to both a single image and a movie. The main project will demonstrate many common and undocumented techniques, while each project introduces and examines tools and techniques for successful and fun animation of ideas or scripts.Each project of the book including the main project is designed to cover the aspects of 3D animation in a manner which anyone with basic computer skills can follow. You will discover the importance of lighting a scene including daytime scenes. The concept of the timeline and key frames will be covered in detail and other topics such as rendering (exporting), character modification and prop placement all have their own sections with step by step instructions followed by an explanation of what just happened. Good animation habits and project basics are stressed throughout the book interspersed with time saving tips and techniques gained from years of experience with iClone.When you have finished The iClone 3D Animation Beginner’s Guide you will have a solid foundation in the basics of iClone by having animated a scene with multiple characters and props that involves dialog and interaction with other characters. You will have the knowledge to create new animation projects to hone your skills, tell your story, educate students or sell your product.

Preface

Rigid bodies


A rigid body is indeed a hard object but it's a little more than that, as deformations to the object are not possible when set as a rigid body. The rigid body object will always maintain its shape without a mushy, gelatinous, or spring effect.

Rigid body prop examples would be a bowling ball, wall, floor, or any object that is solid and would not oscillate when a collision occurs. If it shakes or quivers, then it's a soft body, as will be discussed in due time, otherwise, it's a rigid body as a rule of thumb.

Setting the state of the object

The state of the object is crucial in defining how the object will react to the simulation. What state you choose depends on what you need that particular object to do. Let's take a moment to discuss the various states and their uses. Once again Jason Lin at Reallusion was invaluable in getting this information for us to use:

Dynamic

For use with objects whose intent is passive, such as free fall or collisions.

Kinematic

Use with rigid body groups that you wish to key frame or puppet (animate) and for collision props linked to an animated character or object.

Static

Objects that do not allow penetration or reaction from another physics driven object, such as a floor or wall that will provide containment for the simulation instead of the objects passing through. Static objects are not moved by the collision effect.

Frozen

Objects that need to be held in place until dislodged or touched by another physics driven object, such as a group of dominoes, a stack of boxes, barrels, or cans.

Object properties

Mass

Weight and volume. The more mass something has, the more inertia and gravity it will experience.

Friction

A damping effect that can slow down or control spin in some cases.

Damping

Helps to reduce the effect of oscillations or jittery movement.

Elasticity

Bounce or lack of bounce.

Bounding settings

Bound Type

 

Box

Surrounds the object with an invisible collision box and the default settings as of this writing.

Sphere

Surrounds the object with an invisible collision sphere.

Cylinder

Surrounds the object with an invisible collision cylinder.

Capsule

Surrounds the object with an invisible collision capsule.

Convex Hull

Surrounds the object with an invisible collision hull that would be like wrapping it with a plastic wrap as it fits to the object in that manner.

Bounding Mesh

Surrounds the object with an invisible collision Bounding Mesh, usually a simple low poly box.

Self Mesh

Surrounds the object with an invisible collision mesh based on the objects form.

Bound Axis

 

Used with cylinder and capsule bounding type to set the orientation axis.

 

We need to visualize what we are doing when working with bounding types as they have a dramatic effect on a simulation.

Note

Bounding a capsule prop with a box will negate the curves of the capsule when in contact with other physics props, so always check that the Bounding Type matches the objects shape as closely as possible.
