introduction

In 3D computer graphics, 3D modelling (also known as meshing) is the process of developing
a mathematical representation of any three-dimensional surface of object (either inanimate or
living) via specialized software. The product is called a 3D model. It can be displayed as a two-
dimensional image through a process called 3D rendering or used in a computer simulation of
physical phenomena. The model can also be physically created using 3D printing devices.
Models may be created automatically or manually. The manual modelling process of preparing
geometric data for 3D computer graphics is similar to plastic arts such as sculpting.
Compatibility with popular graphics and 3D modelling software lets you model realistic or
highly-stylized characters, weapons, vehicles, and props within the Source environment. A robust
set of tools help you efficiently rig, animate, and define physics interactions for a wide range of
characters and objects.
The 3D Canvas is a 3D modelling and animation tool developed by Amabilis. It is available in
three different versions—3D Canvas, 3D Canvas Plus, and 3D Canvas Pro. 3D Canvas is freeware,
whereas the Plus and Pro upgrades cost. The upgraded versions allow for a larger number of
import and export formats, as well as a number of additional functions. The software is designed
to be user-friendly, and has an easy to use drag and drop interface.

10.1 advanced animation tools

skeletal animation system: Articulate models with fluid and complex motion using Valve’s
proprietary skeletal animation system.

facial animation system: Valve’s proprietary facial animation system seamlessly blends a wide
range of facial expressions for natural, emotion-driven speech and movement. With more than 40
distinct facial “muscles”, human characters convey the full array of human emotion and respond
to the player with fluidity and intelligence.

animation Blending: Seamlessly blend gestures to create continuous movement or add depth
to any character situation.
