Abstract
An image processing apparatus and an image processing method reconstruct a three-dimensional image of an object which expresses a texture, glossiness, and three-dimensionality with realism. The image processing apparatus produces, from a physical object, data representing a shape and a surface feature of the physical object, holds the data as a three-dimensional model, and presents a three-dimensional image under conditions of an illumination environment and line of sight designated by a user when the three-dimensional image is reconstructed. To present the three-dimensional image at a high speed with realism, the apparatus and method use new and particularly advantageous features in a generation process and in a data format used in the three-dimensional model.
