snapElement

com.nutiteq.components.Vector snapElement(com.nutiteq.geometry.VectorElement element,
                                        com.nutiteq.components.Vector delta)

Adjust object movement, usable for snapping

Parameters:

element - which was moved

delta - element movement Vector

Returns:

adjusted movement Vector if snapping is done, same as input if not

snapElementVertex

                                              int index,
                                              com.nutiteq.components.MapPos mapPos)

Adjust vertex movement, useful for snapping

Parameters:

element - element which was edited

index - index of vertex which was edited

mapPos - A MapPos where vertex was moved to

Returns:

adjusted MapPos if snapping is done, same as input mapPos if not
