getRayFromMouse

public final Line getRayFromMouse(Line ray,
                                  int x,
                                  int y)

Ray starting a modelview position towards to direction pointed by the mouse (x,y) coordinates within this SceneView viewport. (0,0) is bottom left

Parameters:

ray - destination to store result

x - position along horizontal axis

y - position along vertical axis

Returns:

ray

unProject

public boolean unProject(Vec3 win,
                         Vec3 obj)

Equivalent to gluUnProject

Parameters:

sceneView - Specifies the scene which contains the modelview, projection and viewport

win - Specify the window coordinates to be mapped.
Usually (x,y) is the mouse coordinate and z is requested with :

obj - returns the computed object coordinates

Returns:

true if succeed
