摘要： A model object MOB (tree) having a plurality of part objects (branches) POB1 and POB2 each of which has a projection shape is arranged in an object space. Each of the POB1 and POB2 has a projecting portion formed on a display surface on which an image is drawn. The POB1 and POB2 are rotated so that the display surfaces thereof are directed toward a virtual camera VC. A Z texture for setting bump shapes on the display surfaces by pixel unit or forming a virtual projection shape on each of the display surfaces is mapped on the POB1 and POB2. When the VC rotates about a Y-axis and an X-axis while being directed toward a column-shaped part object (trunk) COB, the POB1 and POB2 are rotated so that the display surfaces thereof are directed toward the VC.

摘要： An efficient graphics pipeline with a pixel cache and data pre-fetching. By combining the use of a pixel cache in the graphics pipeline and the pre-fetching of data into the pixel cache, the graphics pipeline of the present invention is able to take best advantage of the high bandwidth of the memory system while effectively masking the latency of the memory system. More particularly, advantageous reuse of pixel data is enabled by caching, which when combined with pre-fetching masks the memory latency and delivers high throughput. As such, the present invention provides a novel and superior graphics pipeline over the prior art in terms of more efficient data access and much greater throughput. In one embodiment, the present invention is practiced within a computer system having a processor for issuing commands; a memory sub-system for storing information including graphics data; and a graphics sub-system for processing the graphics data according to the commands from the processor. The graphics sub-system comprises a rasterizer for traversing graphics primitives of the graphics data to generate pixel coordinates for pixels corresponding to the graphics primitives; a graphics pipeline for processing the graphics data of the pixels; and a pixel cache for caching the pixel data. In this embodiment, he graphics sub-system masks the inherent latency of the memory sub-system by pre-fetching the graphics data and storing the graphics data within the pixel cache.

摘要： A method of generating a three-dimensional image of an object includes placing a video camera at a predetermined distance from the object, such that the video camera has an unobstructed view of the object, and causing the object to rotate about a central axis. A video stream of at least one revolution of the rotating object is captured with the video camera. A period of the at least one revolution of the object is determined. A predetermined number of frames of the captured video stream are selected, and a three-dimensional image of the object using the selected frames is created.

摘要： A method and system for the processing, compressing, streaming, efficient transmission, and interactive rendering of 3d color image data are presented. A 3d color image is defined as a collection of 3d xyz locations that possess red-green-blue (RGB) color components just as a conventional 2d color image is a set of 2d xy locations (pixel centers) that possess RGB color components. One major difference is that 2d color images are generally dense and specifically organized on a 2d pixel grid where 3d color images are generally sparse and not organized on a dense-voxel grid in their raw data formats. The described method uses 3d sampling techniques and view-dependent point-size rendering algorithms to provide real-time interactive displays of complex textured 3d objects and scenes without the use of specialized texture mapping support for polygons within 3d graphic display systems. By combining this point-based rendering and modeling approach with an efficient data compression technique that offers a high compression ratio, interactive, realistic 3d graphics can be delivered over relatively low bandwidth channels to devices without custom texture-mapping graphics capabilities.

摘要翻译： 提出了一种用于3D彩色图像数据的处理，压缩，流式传输，高效传输和交互式渲染的方法和系统。 3D彩色图像被定义为具有红 - 绿 - 蓝（RGB）颜色分量的3d xyz位置的集合，就像传统的2d彩色图像是具有RGB颜色分量的一组2d xy位置（像素中心）一样。 一个主要的区别是二维彩色图像通常是密集的，并且具体组织在2d像素网格上，其中3d彩色图像通常是稀疏的，而不是以原始数据格式的密集体素格网格组织。 所描述的方法使用3d采样技术和视图相关的点尺寸渲染算法来提供复杂纹理3D对象和场景的实时交互式显示，而不需要在3d图形显示系统内使用针对多边形的专门的纹理映射支持。 通过将这种基于点的渲染和建模方法与提供高压缩比的高效数据压缩技术相结合，可以将交互式，逼真的3D图形通过相对较低的带宽通道传递到没有自定义纹理映射图形功能的设备。

摘要： Method and apparatus for creating 3D-prints and a 3-D printing system A method and apparatus for creating a print file for printing a 3-D print using a 3-D printing system is described, the 3-D print comprising a plurality of 3-D structures printed on a substrate, each 3-D print structure having a height with respect to the substrate. A two-dimensional source image is input comprising a plurality of image pixel areas. A filtered image is obtained by applying a topographic operator to the source image to generate for every image pixel a representation of a pixel height profile, the pixel height profile corresponding to cross-sections through a 3-D print structure which is to be formed by 3-D printing. Thereby definitions of a plurality of image layers are generated from the filtered image for printing using the 3-D printing system. The print file is output based on the plurality of image layers. The topographic operator has the following property: any cross-section through a solid section of a 3-D structure at a second level in the 3-D print structure which is closer to the substrate than a first level has an area which is equal to or larger than the area of the cross-section of the 3-D structure at the first level.
