Abstract
An image processing apparatus which enables three-dimensional modeling and a full variety of computer graphic animation. For this purpose, the apparatus inputs three-dimensional data of a plurality of objects, and independently sets texture animation state values and change amounts for the respective objects. As texture animation is started, display of each object changes in a real-time manner from the initial display state in accordance with a change amount.
