Abstract
In order to reproduce a sculpture from a lumber in wood carving,it is often practiced to transfer the drawing to the surface of the lumber and to cut out the outline in the shape of a silhouette.While the shape to be carved becomes clear to a certain extent,the guiding standard such as the drawing on the flat surface of the lumber will be carved and inevitably lost.So beginners are not be able to proceed from a certain stage in many cases.In this research,3 D data is viewed by free position and angle,and the chamfering workｓof cutting a corner or edge of wood to create a plane is simulated on a computer.Then the process up to the stage which is the rough shape of the reproduction is considered in advance.The author also refers to the accuracy and efficiency of the wood carving based on the volume ratio of the original image and the model cut from the lumber.
