Morphing operation is a smooth changeover of shape of 3D object between two or more object patterns. Morphing pursues changing coordinates of individual vertices of object. With help of the
add pattern for morphing element next pattern for morphing is added to the
active object. Identification number of object used as a pattern is passed on as an element parameter. Only present appearance of object is kept from the pattern object, object itself is no more needed and can be deleted. Another morphed object or active object itself can be used as a pattern object, too. Number of pattern objects can be arbitrary. Setting -1 value as an element parameter will cause deleting all morphing patterns. The object becomes usual object, its appearance remains preserved according to its last morphing state.
