Description

The VO CameraControl command enables you to define the path that the virtual camera takes during a technical animation.

The following table describes basic options to follow, stop following, hide or show the graphics of a camera path in a particular 3D Graphics window for a specific scenario.

Additional {CameraOptions} described below allow for detailed definitions of camera paths and keyframes. These options are CameraPath, KeyframeProps, 3DWindowProps, RenderProps and Keyframes.

Examples

To follow the "Path 4" camera path in the 3D Graphics window 2, without a soft transition:

To stop following any camera path in the 3D Graphics window 1:

To follow the "Path0" camera path in the 3D Graphics window, but don't show the graphics:

CameraPath

Use this option to manage camera paths.

The syntax for the commands to add, modify, delete and duplicate a CameraPath are listed here.

Syntax to Add or Modify a camera path, valid {AddModifyOptions} are described in the following table.:

VO <ScenarioPath> CameraControl CameraPath {Add | Modify} {AddModifyOptions}

Syntax to Delete a camera path, specify the name of the camera path to delete:

VO <ScenarioPath> CameraControl CameraPath Delete Name "<CameraPathName>"

Syntax to Duplicate a camera path. Specify the from and to camera path names:

VO <ScenarioPath> CameraControl CameraPath Duplicate FromName "<CameraPathName>" ToName "<CameraPathName>"

Examples

To add a camera path called Path2:

To modify the color of Path2:

To create a duplicate of Path2 named Path4:

KeyFrameProps

Use this option to set keyframe properties.

VO <ScenarioPath> CameraControl KeyFrameProps "<CameraPathName>" {KeyframeOptions}

Enter "<CameraPathName>" to specifiy the camera path being modified. The following table describes the {KeyframeOptions}.

Examples

To enable ripple times for Path2:

To set the reference axes for Path2:

3DWindowProps

Use this option to define camera control properties of a particular 3D graphics window.

VO <ScenarioPath> CameraControl 3DWindowProps {WindowOptions}

The following table describes the {WindowOptions}.

Follow mode cannot not be enabled while enabling an edit mode.

Examples

To esable follow mode:

To set the modes and active path:

RenderProps

Use this option to set properties for drawing camera paths in the 3D windows.

VO <ScenarioPath> CameraControl RenderProps {RenderOptions}

The following table describes the {RenderOptions}.

For valid {Color} options see Common Options.

Examples

To turn off the display of keyframe points:

To set the color of control points:

KeyFrames

The syntax for the commands to add, delete or modify a keyframe are listed here. In each command you must specify the "<CameraPathName>" where the keyframe can be found.

Syntax to Add a keyframe, note you can optionally include the 3D window ID:

VO <ScenarioPath> CameraControl KeyFrames "<CameraPathName>" Add [WindowID <WinNumber>]

Syntax to Delete a keyframe, also include the keyframe number or enter All to delete all keyframes:

VO <ScenarioPath> CameraControl KeyFrames "<CameraPathName>" Delete {<KeyframeNum> | "All"}

Syntax to Modify a keyframe. Specify the <KeyframeNum> and {ModifyOptions}. Valid {ModifyOptions} are described in the following table:

VO <ScenarioPath> CameraControl KeyFrames "<CameraPathName>" Modify <KeyframeNum> {ModifyOptions}

Examples
