Zoom In/Out

In Bryce, there is a difference between moving the camera and using the zoom tools. When you move the Camera, you're moving in 3D space. When you use the pan and zoom controls, you're transforming a 2D projection of your 3D scene - your camera position does not change.

When you use the Zoom tool, you are essentially making the 2D projection larger or smaller. Your camera position in 3D space does not change.

To zoom in, click on the Zoom In tool. Bryce scales the 2D projection of your scene larger, creating the illusion of zooming into your 3D scene; your camera position remains unchanged. Keyboard shortcut: plus (+)
To zoom out, click the Zoom Out tool. Bryce scales the 2D projection of your scene smaller, creating the illusion of zooming out of your 3D scene. Your camera position remains unchanged. Keyboard shortcut: minus (-)
To zoom into a specific area, hold down Cmd/Ctrl+Spacebar and drag a marquee around an area of your scene. Your cursor changes to a Zoom tool and Bryce centers and scales up the area in the marquee to fit your window. See "Zoom to Selection" to see this in action.
To zoom using the mouse, hold down Cmd/Ctrl+Opt/Alt+Spacebar and drag the mouse left or right in your scene. Dragging left zooms in and dragging right zooms out.
To zoom numerically:

Double-click the Trackball in the Control palette. The Camera & 2D Projection dialog appears.
Enter a value in the Scale field. The default value is 100%. You can only zoom numerically when you are working in either Director's View or Camera View.

To reset the zoom value, press the Opt/Alt key and click on the Zoom tool. The view of your scene resets to 100%.
