Chapter 1 ✦ An Introduction to Maya

3D modeling

Perhaps, the best way to describe this function is 3D modeling clay, or creating 3D

shapes. When you create a model in 3D, you use Maya’s toolset to define shapes or

geometry, much as a sculptor in the real world uses a practical toolset. The three

surface types, used to describe a shape in Maya 4.5, are polygons, NURBS, and sub-

division surfaces. Maya surface types describe a polygon surface that you view or

render. 3D Models are used for many different functions including animation, design,

manufacturing, previsualization, virtual reality, and games.

For more on 3D Modeling, see Part II, “Modeling.”

Film and television special effects

This special effects function includes elements ranging from digital actors to char-

acter animation to virtual simulated worlds to lighting effects, to explosions to set

generation to water splashes or sprays to flying logos. Most of the special effects

that we see everyday in movies and on television are created in Maya. Sometimes

the effects are so subtle and well-executed that we can’t even detect them. Other

times, the effects are so fantastic that we can’t ignore the amazing special effect.

Particle and object dynamics simulations

Dynamics are used for scientific visualizations, and fluid simulations. Dynamics

are also used with 3D animation that requires real world forces such as gravity or

collisions. Rigid body dynamics affect shapes and surfaces. Particle dynamics affect

points in space. They are very useful in simulating gasses and liquids, as well as large

groups of objects or image sprites. Softbody dynamics use particles to animate the

control points of a 3D surface. The Star Wars, Episode One, “Pod Racer” scene is the

most notorious use of Maya’s dynamic engine to create a fantastic effect.

For more on Dynamics, see Chapter 27, “Using Dynamics.”

3D game animation

Maya has many tools designed to create 3D games with real-time rendering engines.

Gaming requires a slew of tools to reduce computation times and still enable you to

get a believable look though efficient use of texture space and surface geometry.

Maya also enables you to previsualize the game engine, using game translators and

real-time hardware rendering engines.
