摘要： View-dependent texture images and view-independent texture data for a 3D computer model are processed to compress each view-dependent texture image by subtracting the view-dependent data and view-independent data in a common 2D image space to generate a difference image, and compression encoding the difference image. The difference images, 3D computer model and view-independent texture data are transmitted to a second apparatus, where the difference data and view-independent texture data are recombined in a common 2D image space as part of the processing to render an image.

摘要： A plurality of texture maps for a 3D computer model of an object are generated by processing images of the object, data defining the computer model, and data defining the relative positions and orientations of the images and computer model. A respective texture map is generated for the viewing position and direction of each image. Each texture map stores texture data for all parts of the computer model which are visible from the associated viewing position and direction and also texture data for all invisible parts of the computer model. Each texture map therefore stores texture data that can be used for rendering accurate images of the 3D computer model over a wide range of viewing positions and directions.
摘要翻译：通过处理对象的图像，定义计算机模型的数据以及定义图像和计算机模型的相对位置和取向的数据来生成用于对象的3D计算机模型的多个纹理图。为每个图像的观看位置和方向生成相应的纹理图。每个纹理贴图存储从相关观看位置和方向可见的计算机模型的所有部分的纹理数据，以及计算机模型的所有不可见部分的纹理数据。因此，每个纹理贴图存储可用于在宽范围的观看位置和方向上渲染3D计算机模型的精确图像的纹理数据。

摘要： This invention introduces, as one aspect, an apparatus for creating three-dimensional object model, comprising photographing means for photographing an object to be modeled for obtaining images to be used for creating the three-dimensional object model, setting means for longitudinally and latitudinally setting a relative position between the object and said photographing means, said setting means being capable of setting the object and said photographing means a plurality of different relative longitudinal and latitudinal positions, and control means for controlling said photographing means and said setting means so that a number of photographs taken from different relative longitudinal positions at a first relative latitudinal position is larger than that taken from different relative longitudinal positions at a second relative latitudinal position, the first relative latitudinal position being closer to a lateral position than the second relative latitudinal position. Accordingly, it becomes possible to minimize the number of photographs for obtaining necessary images to effectively keep a high quality three-dimensional object model, the number of user's manual operations is reduced, and the total photographing time for creating a three-dimensional object model is significantly decreased.
