Workflow des outils
- View Control with the Camera Toolbar
The Camera toolbar enables you to perform a number of viewing operations interactively.
- Camera Graphics Terminology
Graphics provides functionality, analogous to that of a camera with a zoom lens, that enables you to control the view of the scene.
- Understanding View Projections
Graphics supports both orthographic and perspective projection types for displaying 3-D graphics. The one you select depends on the type of graphics you are displaying.
- Low-Level Camera Properties
Camera graphics is based on a group of axes properties that control the position and orientation of the camera.
- Setting the Viewpoint with Azimuth and Elevation
You can control the orientation of axes using graphics functions.
- Dollying the Camera
camdollyfunction allows you to move both the position of the camera and the position of the camera target in unison.
- Moving the Camera Through a Scene
This example shows how to move a camera along a path traced by a stream line and how to move a light source with the camera.
- Manipulating Axes Aspect Ratio
There are several axes properties that control the aspect ratio. Set these properties to achieve the effect you want.
