摘要： An urban scenes reconstruction method includes: acquiring digital data of a three-dimensional subject, the digital data comprising a 2D photograph and a 3D scan; fusing the 3D scan and the 2D photograph to create a depth-augmented photograph; decomposing the depth-augmented photograph into a plurality of constant-depth layers; detecting repetition patterns of each constant-depth layer; and using the repetitions to enhance the 3D scan to generate a polygon-level 3D reconstruction.

摘要： An apparatus and method for real-time volume processing and universal three-dimensional rendering. The apparatus includes a plurality of three-dimensional (3D) memory units; at least one pixel bus for providing global horizontal communication; a plurality of rendering pipelines; at least one geometry bus; and a control unit. The apparatus includes a block processor having a circular ray integration pipeline for processing voxel data and ray data. Rays are generally processed in image order thus permitting great flexibility (e.g., perspective projection, global illumination). The block processor includes a splatting unit and a scattering unit. A method for casting shadows and performing global illumination in relation to light sources includes sweeping a two dimensional array of rays through the volume can also be implemented with the apparatus. A method for approximating a perspective projection includes using parallel projection.

摘要： An ink cartridge with ink tanks for a printer including a bottom case, a cover, and ink tanks is provided. Inks are classified and stored into independent ink tanks which are assembled in the bottom case. The ink tank includes a negative pressure mechanism for controlling a flow rate of the ink. Soft films are welded on both sides of an ink tank support. During the printing, the inks in the ink tanks a flow through the negative pressure mechanism and get into an inkjet cavity. The ink tank does not have an air intake system, and a volume of the ink tank is changed by changing the shape of the soft films. Thus, the air is isolated from the inks in the ink tanks, and will not get into an ink outlet port.

摘要： An apparatus and method for real-time volume processing and universal three-dimensional rendering. The apparatus includes a plurality of three-dimensional (3D) memory units; at least one pixel bus for providing global horizontal communication; a plurality of rendering pipelines; at least one geometry bus; and a control unit. The plurality of rendering pipelines each preferably include hardware for interpolation, shading, FIFO buffering, communication and table lookups. The apparatus of the present invention may be coupled to a geometry pipeline for mixing surfaces, images and volumes together in a single image. A method for performing volumetric ray casting of a 3D volume includes the steps of calculating a distance along a major projection axis from a predefined viewpoint; dividing the volume into a plurality of consecutive regions having exponentially increasing bounds; casting a plurality of rays from the viewpoint through the volume; either merging two or more rays or splitting one or more rays at the region boundaries; and repeating the ray casting and merging/splitting steps until the entire volume has been processed. The apparatus and methods of the present invention achieve true real-time performance for high-resolution volume rendering, mixing surfaces and volumes in a single image, and accelerating other imaging operations, including texture mapping and image-based rendering.
