About Atmosphere Builder

The Atmosphere Builder application provides tools for building virtual three-dimensional

worlds and publishing them on the Web. Users can explore published worlds on the Web

using the Atmosphere Browser. The experience of exploring a world is much like a video

game, except that Atmosphere Builder worlds can be linked together and explored over the

Internet at realistic speeds, with high resolution, realistic lighting effects, and in full color.

Users that are exploring the same world can see representations of each other called

avatars

, and converse with one another by typing messages in a chat window.

Creating and opening worlds

When you start Atmosphere Builder for the ﬁrst time, you will see a variety of palettes and

a menu bar. The menus at the top of your screen provide access to commands, and the

palettes contain tools and options for building a 3D world. When you create a new world

or open an existing world, a document window appears on your screen. You can have only

one document window open at a time.

To create a new world:

Choose File > New.

To open a world:

Choose File > Open.

Select the name of the ﬁle you want to open, and click Open.

Note:

You can only open Atmosphere ﬁles using the Open command. For information on

importing Viewpoint ﬁles, see “Importing objects” on page 14.

Atmosphere Builder Basics

Working with views

The document window displays a

view

of the objects in a world. You can choose one of

three wireframe views to see a blueprint representation of your world called a

wireframe

;

or you can choose Browser view to see your world with its surface textures, colors, and

lighting. Browser view shows you how your world will appear when viewed on the Web in

the Atmosphere Browser.

About views

Building a world is easier when you understand how to use the different views. If you’ve

ever worked in a 3D modeling application or sketched out plans for a building project,

you’re already familiar with the concept of using views. Atmosphere Builder provides four

ways to view a world. The three wireframe views show you the structure of the world and

how the objects are connected to each other; the fourth view shows a preview of the world

as it will appear in the Atmosphere Browser with surface textures, colors, and lighting

applied to objects.

Top view

Shows the top of the wireframe from a position directly above it. When you ﬁrst

create or open a world, this is the initial view in the document window.

Side view

Shows the side of the wireframe. You’ll frequently switch between the Top view

and Side view when placing and aligning objects in Atmosphere Builder.

Isometric view

Shows the wireframe from an oblique angle that is above and to the side

of it. Isometric view is useful for getting an overview of where objects are in the world.

User Guide

Browser view

Shows a rendered, three-dimensional view of your world that you can move

through and explore. You use Browser view to apply surface textures and colors to the

objects you created in wireframe view, and to adjust the lighting in the world. Keep in

mind that what you see in Browser view is what users will see on the Web.

Selecting a view

You can use the Views palette or the Views menu to select a view.

To display the Views palette:

Choose Window > Views.

To select a view:

Do one of the following:

•

Click a view in the Views palette.

•

Choose a view from the View menu.

Navigating in wireframe views

Navigating is essential to building a world. You can scroll, rotate, magnify, and reduce a

view to better see the portion of the wireframe you want to work on.

Atmosphere Builder Basics

Scrolling wireframe views

If the area of the wireframe you want to work on is not visible in the document window,

you can scroll to bring that area into view.

To scroll a view:

Select the pan tool

()

, and drag in the document window.

Rotating wireframe views

You can rotate a wireframe view in the document window to see the objects from a

different perspective. Keep in mind that rotating the view does not change the orientation

of individual objects, only the angle at which you see the wireframe as whole. For infor-

mation on rotating individual objects, see “Rotating objects” on page 40.

To rotate a view:

Select the rotate objects tool

()

Drag to the left in the document window to rotate the view clockwise; drag to the right

to rotate the view counter-clockwise.

Magnifying and reducing wireframe views

You can magnify your view to see the wireframe in greater detail, or you can reduce your

view to see a larger portion of the wireframe. Keep in mind that zooming in and out does

not change the actual size of the objects, only the magniﬁcation at which you see them.

For information on changing the scale of objects, see “Scaling and distorting objects” on

page 41.

To zoom in and out by dragging:

Select the zoom tool

()

Drag to the right in the document window to zoom in, or to the left to zoom out. Your

view zooms in and out on a continuous range of percentages based on how much you drag.

To zoom in by clicking:

Select the zoom in tool

()

, and click a point in the wireframe around which you want

to magnify.

ADOBE ATMOSPHERE

User Guide

To zoom out by clicking:

Select the zoom out tool

()

, and click a point in the wireframe around which you want

to reduce magniﬁcation.

Centering wireframes in the document window

After navigating in the wireframe views, you can quickly display all of the objects in the

wireframe and center the view in the document window.

To center a wireframe in the document window:

Choose View > Fit All.

Navigating in Browser view

Browser view presents a shaded, perspective view of a world. You can navigate around this

world using your mouse and keyboard commands. You can move forward and backward

through doorways, climb up and down stairs, and look side to side. You can also set

options that determine the quality of your movement.

To navigate in Browser view:

Select the move tool

()

Do one or more of the following:

•

Drag in a world to change your point of view: drag to the left to turn left, drag to the

right to turn right, drag up to move forward, and drag down to move backward.

•

Press an arrow key to change your point of view: press the left arrow key to turn left, the

right arrow key to turn right, the up arrow key to move forward, and the down arrow key

to move backward.

•

Shift-drag up or down, or hold down Shift+up arrow key or Shift+down arrow key, to

move vertically in the world. Shift-drag right or left, or hold down Shift+right arrow key

or Shift+left arrow key, to move horizontally (side to side) in the world.

•

Ctrl-drag to rotate around your current position (as if you are turning your head and

looking). When you Ctrl-drag to the side, your subsequent movement is determined by

the direction in which you are looking. For example, if you Ctrl-drag to the right, release

the Ctrl key, and then drag forward, you will move along a forward trajectory to the right.

Atmosphere Builder Basics

To set move tool options:

Select the move tool

()

Display the Tool Inspector palette. (See “Using the Object Inspector palette” on

page 16.)

Select or deselect the following options:

•

Collide to specify whether or not you can move through objects. If you select Collide,

objects in the world, like walls, ﬂoors, and so on, will block your passage. If you deselect

Collide, you will be able to move through objects in the world without resistance.

•

Gravity to specify the effects of gravity on your movement. If you select Gravity, you are

drawn to the ﬂoor or ground plane of the world. If you deselect Gravity, you can change

your vertical position and hover above or below the ground plane of the world.

Note:

When you deselect Collide, Gravity is implicitly disabled (although the Gravity

checkbox does not change). When you reselect Collide, Gravity is reenabled.

Using the Actor object

The Actor is a special object that appears in each wireframe view and reﬂects your current

location and orientation in the Browser view.

Moving the Actor object in a wireframe view changes your position in Browser view.

To change your position and orientation in Browser view using the Actor object:

Select a wireframe view: Top, Side, or Isometric.

Select the Actor object

(

)

. (See “Selecting objects” on page 30.)

Drag the Actor object to the desired position in the wireframe.
