Remarks

This class allows the user to define a view which contains a scene.

Views allow the application to specify multiple cameras, each with its own separate viewport (region of the 3D window). This is more powerful than just using multiple OIV.Inventor.Nodes.SoCamera nodes, because camera nodes do not allow specifying a viewport (the viewport is always the full window). See OIV.Inventor.Gui.View.PoBaseView for more explanation.

A scene is a set of any nodes (except OIV.Inventor.Nodes.SoCamera nodes) placed under an OIV.Inventor.Nodes.SoGroup node which must be seen in a viewport according to a camera configuration. To define a view, set the fields viewportOrigin and viewportSize according to the viewport position and size you want to have (relative to the display window sizes), configure the camera (set the part cameraKit), build the scene under an OIV.Inventor.Nodes.SoGroup node, and set this scene to the view (set the part scene). All shape nodes contained in the scene will be drawn in the viewport previously defined and according to the camera definition. You can define as many views as you want.

NOTES:

If you use a viewer, you should call the method SoBaseKit.setSearchingChildren(true) to allow the viewer to search for cameras inside nodekits (like this one).
Do not place a camera node before this nodekit.
Create a camera for each view and set it using the setPart method. See example.
When you use HardCopy, the graphics window is the paper sheet.
LIMITATIONS:
The field OIV.Inventor.Nodes.SoCamera.viewportMapping must be equal to ADJUST_CAMERA in order to have a correct vectorisation when you use HardCopy,
Do not use the OIV.Inventor.Actions.SoBoxHighlightRenderAction class on a scene graph which contains a view,
Do not push view,
Be careful when you use the method viewAll() of the class SoXtViewer, because this method works on the entire scene graph and not on a portion of a scene graph. Overload this method according to your requirements,
Some of the viewer functions/buttons do not work correctly with views. For example, saveHomePosition() and resetToHomePosition() do not work correctly because the viewer only stores one copy of the camera.
The viewer rendering options, e.g. wireframe, apply to ALL views inside the viewer. You can implement these effects per-view using an OIV.Inventor.Nodes.SoDrawStyle node and OIV.Inventor.Nodes.SoNode.SetOverride(System.Boolean) if necessary.
In case of tile rendering with OIV.Inventor.SoOffscreenRenderArea : OIV.Inventor.Nodes.SoGradientBackground in a OIV.Inventor.Gui.View.PoSceneView will not be rendered with the correct size (i.e. the OIV.Inventor.Nodes.SoGradientBackground size will not match the target size). Call SoOffscreenRenderArea.setTileSize() with the offscreen rendering total size to avoid this size problem.

EXAMPLE

Copy

SoBaseKit.SetSearchingChildren(true);

SoSeparator scene1 = new SoSeparator();
scene1.AddChild( new SoCone() );

PoSceneView view1 = new PoSceneView();
view1.SensitiveOnEvents(true);
view1.isBorderVisible.Value = true;
view1.viewportOrigin.SetValue(0, 0);
view1.viewportSize.SetValue(0.5f, 0.5f);
SoPerspectiveCamera cam1 = new SoPerspectiveCamera();
view1.SetPart("cameraKit.camera", cam1);
view1.SetPart("scene", scene1);
cam1.ViewAll(scene1, new SbViewportRegion(100, 100));
root.AddChild(view1);

SoSeparator scene2 = new SoSeparator();
scene2.AddChild( new SoCube() );

PoSceneView view2 = new PoSceneView();
view2.SensitiveOnEvents(true);
view2.isBorderVisible.Value = true;
view2.Set("borderApp.drawStyle", "lineWidth 1.5"); // Work-around for border
view2.viewportOrigin.SetValue(0.5f, 0.5f);
view2.viewportSize.SetValue(0.5f, 0.5f);
SoPerspectiveCamera cam2 = new SoPerspectiveCamera();
view2.SetPart("cameraKit.camera", cam2);
view2.SetPart("scene", scene2);
cam2.ViewAll(scene2, new SbViewportRegion(100, 100));
root.AddChild(view2);

viewer.SetSceneGraph(root);
