Constructor Summary

OrbitCameraHandler(GlContext ctx)
Creates a new orbit camera handler for the compositor camera.

OrbitCameraHandler(GlContext ctx, Camera camera, boolean matchRenderSurface)
Creates a new orbit camera handler for the specified camera.

Method Summary

SphereCoords	getCoords() Returns a reference to the camera's coordinates relative to the target.
Vector3f	getTarget() Returns a reference to the location of the camera's target.
Vector3f	getViewerTranslation() Returns a reference to the translation to use for the notional "viewer."
void	orbit(float azimuth, float elevation) Adjusts the azimuth and elevation of the camera by the specified amounts.
void	pan(float x, float y) Pans the target by the specified amounts relative to the camera's current orientation.
void	panXY(float x, float y) Pans the target on the XY plane by the specified amounts relative to the camera's current orientation.
void	setCoordLimits(float minElevation, float maxElevation, float minDistance, float maxDistance) Sets the limits on the camera's relative coordinates.
void	zoom(float distance) "Zooms" in (if negative) or out (if positive) by the specified amount.
