public interface IRenderAreaInteractive
extends IRenderArea

Interface for interactive render area.
An interactive render area has a SceneInteractor node as root of the scene graph.

Nested Class Summary

Nested Classes

Modifier and Type	Interface and Description
static class	IRenderAreaInteractive.ClippingPlanesAdjustMode Camera clipping planes adjustment mode. When adjustment mode is set to AUTO, the camera near and far planes are dynamically adjusted to be as tight as possible (least amount of stuff is clipped) before each render traversal. When adjustment mode is set to MANUAL, the user is expected to manually set the camera near and far planes.

Method Summary

Modifier and Type	Method and Description
IRenderAreaInteractive.ClippingPlanesAdjustMode	getClippingPlanesAdjustMode() Get the camera clipping planes adjustment mode.
SceneInteractor	getRootSceneGraph() Gets the root scene graph of this render area.
boolean	isStereoSupported() Gets stereo support.
void	restoreCamera() Restore saved camera.
void	saveCamera() Save current camera.
void	setCameraType(SceneInteractor.CameraMode mode) Set camera mode to perspective or orthographic.
void	setClippingPlanesAdjustMode(IRenderAreaInteractive.ClippingPlanesAdjustMode mode) Set the camera clipping planes adjustment mode.
void	setStereoCameraBalance(float balance) Sets the stereo balance (the position of the zero parallax plane).
void	setStereoCameraOffset(float offset) Sets the stereo offset (the distance of each eye from the camera position).
void	viewAll(SbViewportRegion viewport) Set the camera to view all the scene.
void	viewAxis(SbVec3f direction, SbVec3f up) Moves the camera to be aligned with the given direction vector while keeping the "up" direction of the camera parallel to the specified up vector.

Method Detail

getClippingPlanesAdjustMode

IRenderAreaInteractive.ClippingPlanesAdjustMode getClippingPlanesAdjustMode()

Get the camera clipping planes adjustment mode.

setClippingPlanesAdjustMode

void setClippingPlanesAdjustMode(IRenderAreaInteractive.ClippingPlanesAdjustMode mode)

Set the camera clipping planes adjustment mode.
When adjustment mode is set to AUTO, the camera near and far planes are dynamically adjusted to be as tight as possible (least amount of stuff is clipped) before each render traversal.
When adjustment mode is set to MANUAL, the user is expected to manually set those planes. Updating clipping planes after a camera move is not enough, if a dragger or a rendered shape is moved, they can disappear or become partially clipped.
Default is AUTO.

getRootSceneGraph

SceneInteractor getRootSceneGraph()

Gets the root scene graph of this render area.

Returns:

the root scene graph

viewAll

void viewAll(SbViewportRegion viewport)

Set the camera to view all the scene.

Parameters:

viewport - the viewport region used to compute the bounding box of the scene.

viewAxis

void viewAxis(SbVec3f direction,
              SbVec3f up)

Moves the camera to be aligned with the given direction vector while keeping the "up" direction of the camera parallel to the specified up vector.

Parameters:

direction - the new view direction vector

up - the new "up" direction

saveCamera

void saveCamera()

Save current camera. The values of the camera fields are saved and can be restored by calling restoreCamera().

restoreCamera

void restoreCamera()

Restore saved camera. The values of the camera fields are restored to the last saved values.

setCameraType

void setCameraType(SceneInteractor.CameraMode mode)

Set camera mode to perspective or orthographic.

Parameters:

mode - the camera mode: perspective or orthographic

isStereoSupported

boolean isStereoSupported()

Gets stereo support.

Returns:

true if stereo is supported

setStereoCameraOffset

void setStereoCameraOffset(float offset)

Sets the stereo offset (the distance of each eye from the camera position). The right eye is moved plus offset and the left eye is moved minus offset.

Parameters:

offset - the stereo offset

setStereoCameraBalance

void setStereoCameraBalance(float balance)

Sets the stereo balance (the position of the zero parallax plane).

Parameters:

balance - the stereo balance
