FisheyeState

public FisheyeState(float aspect,
                    float minmag,
                    float maxmag,
                    float minsize,
                    float maxsize)

Method Detail

setCenter

public void setCenter(float x,
                      float y)

getCoordsys

public int getCoordsys(VobScene vs,
                       int into,
                       java.lang.Object key)

Put the current fisheye coordinate system into the given vobscene. This puts more than one coordinate system, and only the first one uses the given key. The returned one is not matched and should be added to the matcher by the caller.

setCoordsysParams

public void setCoordsysParams()

event

public boolean event(java.awt.event.MouseEvent e)
