Detailed Description

VSG extension Viewer component which moves the camera in a plane.

The Plane viewer component allows the user to translate the camera in the viewing plane, as well as dolly (move foward/backward) and zoom in and out. The viewer also allows the user to roll the camera (rotate around the forward direction) and seek to objects which will specify a new viewing plane. This viewer could be used for modeling, in drafting, and architectural work. The camera can be aligned to the X, Y or Z axes.

Constructor & Destructor Documentation

SoQtPlaneViewer::SoQtPlaneViewer ( QWidget *  parent = NULL,
const char *  name = NULL,
SbBool  buildInsideParent = TRUE,
SoQtFullViewer::BuildFlag  flag = SoQtFullViewer::BUILD_ALL,
SoQtViewer::Type  type = SoQtViewer::BROWSER 

Constructor which specifies the viewer type.

Please refer to SoQtViewer for a description of the viewer types.


    On Windows, the constructor will not create a new top level window -- you must pass a valid window handle for the parent parameter and pass TRUE for buildInsideParent .

Member Function Documentation

virtual void SoQtPlaneViewer::setCamera ( SoCamera cam  )  [virtual]

Sets the edited camera.

Setting the camera is only needed if the first camera found in the scene when setting the scene graph isn't the one the user really wants to edit.

Reimplemented from SoQtFullViewer.

virtual void SoQtPlaneViewer::setCursorEnabled ( SbBool  onOrOff  )  [virtual]

Sets whether the viewer is allowed to change the cursor over the renderArea window.

When disabled, the cursor is not defined by the viewer and will not change as the mode of the viewer changes. When re-enabled, the viewer will reset it to the appropriate icon.

Disabling the cursor enables the application to set the cursor directly on the viewer window or on any parent widget of the viewer. This can be used when setting a busy cursor on the application shell.

Reimplemented from SoQtViewer.

void SoQtPlaneViewer::setPlane ( const SbVec3f newNormal,
const SbVec3f newRight 

Moves the camera to be aligned with the given plane.

virtual void SoQtPlaneViewer::setSeekMode ( SbBool  onOrOff  )  [virtual]

Set the viewer into/out of seek mode (default OFF).

Actual seeking will not happen until the viewer decides to, for example, on a mouse click.

Note: Setting the viewer out of seek mode while the camera is being animated will stop the animation at the current location.

Reimplemented from SoQtViewer.

virtual void SoQtPlaneViewer::setViewing ( SbBool  onOrOff  )  [virtual]

Sets whether the viewer is turned on or off.

When turned on, events are consumed by the viewer. When viewing is off, events are processed by the viewer's render area. This means events will be sent down to the scene graph for processing (i.e. picking can occur). Note that if the application has registered an event callback, it will be invoked on every message, whether viewing is turned on or not. However, the return value of this callback (which specifies whether the callback handled the event or not) is ignored when viewing is on. That is, the viewer will process the event even if the callback already did. This is to ensure that the viewing paradigm is not broken (default viewing is on).

Reimplemented from SoQtFullViewer.
