CHAPTER 18
The 3D Cast Member, 3D Text, and
3D Behaviors
This chapter introduces several Macromedia Director MX features that let you create a 3D movie:
•
A 3D cast member contains a complex internal structure that includes model resources,
models, lights, and cameras. Each of these objects has its own array of properties.
•
Director MX lets you convert 2D text to 3D and then work with the 3D text as you would
with any other 3D cast member. You can apply behaviors to the 3D text, manipulate it with
Lingo, and view and edit it in the Shockwave 3D window.
•
Director MX comes with a library of behaviors that let you build and control a 3D
environment without any knowledge of Lingo. Although scripting is still required for complex
projects, you can build simple 3D movies with behaviors alone.
About the 3D cast member
Each Director 3D cast member contains an entire 3D world. Each world is a collection of one or
more models and other objects. These objects include the following:
•
Model resources are elements of 3D geometry used to render models. The same model
resource can be used by several models in the 3D world.
•
Models are visible objects in the 3D cast member that use a model resource geometry. For
more information on models, see Chapter 19, “Working with Models and Model Resources,”
on page 473.
•
Shaders are methods of displaying the surface of a model. Shaders control how the surface of
the model reflects light, and whether the surface looks like metal, plaster, or other materials.
•
Textures are simple 2D images that are drawn onto the surface of a 3D model. A model’s
surface appearance is the result of the combination of its shader and any textures that have
been applied to it.
•
Motions are predefined animation sequences that involve the movement of models or model
components. Individual motions can be set to play by themselves or with other motions. For
example, a running motion can be combined with a jumping motion to simulate a person
jumping over a puddle.
•
Lights are sources of illumination within the 3D world. Lights can be directional, such as a
spotlight, or they can be diffuse.
