Create a right handed orbit camera with default up(0,1,0) and right(1,0,0) axis.
param source mouse and keyboard event source
param target node to focus on

public void OrbitController (EventSource source, GLNode target)

Create a right handed orbit camera.
param  source mouse and keyboard event source
param  up upward direction
param  right right direction
param  target node to focus on

public void OrbitController (EventSource source, Vector up, Vector right, GLNode target)

Create an orbit camera.
param  source mouse and keyboard event source
param  up upward direction
param  right right direction
param  target node to focus on
param  rightHanded true for right handed coordinate system, false for leftHanded.

public void OrbitController (EventSource source, Vector up, Vector right, GLNode target, boolean rightHanded)

public boolean isEnable ()

public void setEnable (boolean enable)

Configure a default orbit controller.
return

public OrbitController configureDefault ()

public Sequence getGestureTasks ()

Get pointer warp position.
Works ony if event source is a NewtFrame.
On each mouse event the mouse position is reset to this coordinate.
This allow to avoid mouse hitting the frame borders.
return Tuple can be null

public Tuple getWarpPointer ()

public void setWarpPointer (Tuple autoWarp)

Get distance from target.
return float, distance.

public float getDistance ()

Set distance from target.
param distance

public void setDistance (float distance)

Get horizontal angle.
return horizontal angle in Radians

public double getHorizontalAngle ()

Set horizontal angle.
param horizontalAngle in Radians

public void setHorizontalAngle (double horizontalAngle)

Get vertical angle.
return horizontal angle in Radians

public double getVerticalAngle ()

Set vertical angle.
param verticalAngle in Radians

public void setVerticalAngle (double verticalAngle)

Get roll angle.
return roll angle

public double getRollAngle ()

Set roll angle.
param rollAngle

public void setRollAngle (double rollAngle)

Get minimum camera distance to target.
return minimum camera distance

public double getMinDistance ()

Set minimum camera distance to target
param mindistance minimum camera distance

public void setMinDistance (double mindistance)

Get maximum camera distance to target.
return maximum camera distance

public double getMaxDistance ()

Set maximum camera distance to target
param maxdistance maximum camera distance

public void setMaxDistance (double maxdistance)

When zooming In/Out ,indicate if the step value
is linear or relative to current distance.
If not linear, the distance value must be in range [0..1]
return true if linear

public boolean isLinear ()

Set camera distance calculation type.
param linear true for linear, false for proportional

public void setLinear (boolean linear)

Get step used when zooming In/Out.
return step

public double getStep ()

Set step used when zooming In/Out.
param step

public void setStep (double step)

public void update (RenderContext context, GLNode node)

public void receiveEvent (Event event)
