Objects in the Scene
Every object in the scene has a bounding box. The box acts like a visual guide that tells you how much space it occupies in 3D space. It also provides access to a series of tools that let you edit an object's attributes and placement.
An object's bounding box lets you see how much space it occupies in 3D space.
The buttons around the edges let you set an object's attributes.
The black points on the edges of the box are called control handles. These handles can be used to edit the object's size and orientation. As you pass your cursor over the handles, it changes to display the type of control you're selecting.
When the cursor turns into a letter, it means that you're over a constrain handle. The handle will only move along the axis indicated by the letter. For example, if the cursor changes to a Y, it means that the handle will move only along the Y axis.
If your cursor changes to a letter, it means that you're over a constrained control handle.
You can drag this type of handle to distort the shape of the object.
If the handle changes to a black square with a right angle, it means that the handle can move in any direction, but the object will be scaled proportionally.
If your cursor changes to a black box with a right angle, it means that you can use the handle to proportionally scale the object.
To display an object's bounding box:
Object Preview
When you create an object, it appears as a wireframe in the Working window. The wireframe represents the structure of the object's shape.
Objects appear as wireframes in the scene. The wireframe gives you an idea of the object's shape and structure.
The wireframe preview lets you see how an object looks as it's being rotated or animated without having to calculate and render any complex surface properties. The wireframe casts a shadow on the ground plane below it. The shadow can be used as a visual guide to help you determine the object's position in 3D space.
As you move the object its shadow follows it along the ground plane. When you have a number of objects, the shadows can help you see its exact position in the scene.
If you move the object below the ground plane, the portion of the object that's below ground is not drawn. This can help you avoid placing an object outside the view of the scene. Wireframe shadows do not interact with light; they appear regardless of the light sources in the scene.
If you move an object below ground, the portion of the wireframe that's below the ground plane is not displayed in the scene.
Both shadows and underground wireframes are preview options that can be turned on and off. Refer to "Wireframe attributes" for more on these features.
Object Preview Modes
In addition to wireframes, there are three other ways you can view an object: Bounding Box, Shaded Preview, and Rendered Preview.
Bounding Box
If you have a large scene and you find that it's taking too long to redraw the entire scene, you can change the display of the objects so that only their bounding boxes are displayed.
The Show Object as Box preview mode displays the object using only its bounding box.
You can move the box just as you would a normal object. The box can also cast a shadow.
To display an object as a box:
2 Click Objects menu> Show Object as Box.
or
Click the A icon that appears next to the object's bounding box to display the Object Attributes dialog.In the dialog, click the Show as Box button.
To display an object as a wireframe:
2 Click Objects menu> Show Object as Lattice.
or
Click the A icon that appears next to the object's bounding box to display the Object Attributes dialog.In the dialog, disable the Show as Box button.
Shaded Preview
Open GL mode performance is greatly increased from an Open GL accelerator card, but Windows 95/98 and Windows NT® also support software-driven Open GL mode.
In this mode, objects appear as solids. The colors assigned to the object are also visible. Object surfaces are affected by light sources. Materials and textures are not visible in this mode.
In the shaded preview mode you'll be able to see all the objects in your scene as solids.
Rendered Preview
If you want to see what the object's surface looks like or how it is affected by light gels, you'll have to render it.
The Nano-Preview shows you a small preview of what the object looks like rendered.
Refer to "Using the Nano-Preview" for more on the Nano-Preview.
If you want to see the object at full size you'll have to render it. Once it is rendered, you can see the bitmap preview of the object using the Bitmap Preview mode.
Refer to "Setting Up a Render" for more on rendering and "Display Modes" for more on Bitmap Preview mode
