Two-Handed Manipulation of Tree Models

This paper describes an efficient and intuitive method of tree shape manipulation by using two hands. A user can directly manipulate the shapes of tree models by using a well-designed two-handed interface. The exact manipulation command and partial shape of the user’s intended tree model is automatically embodied and selected from the user’s approximated indication made by using two hands. Experimental results show that our proposed two-handed method is useful for effective manipulation of tree shape models.
