    摘要: A fuel cell (1) is constituted by stacking membrane electrode assemblies (2) and separators (3), wherein fuel gas passages (16), oxidizing gas passages (17) and coolant passages (9), which are formed by the separators (3), are arranged in parallel along the outer surfaces of gas diffusion layers (6A) and (6C) of the membrane electrode assemblies (2). With such a constitution, a thickness dimension of the separators (3) can be reduced, and with respect to a stacking direction of the fuel cell stack, the number of stacked unit cells can be increased in the same dimensions as that of the conventional fuel cell stack. Therefore, a fuel cell stack with a high output density can be obtained.

    摘要: The present invention provides a system and method for eliminating hidden surfaces in 3D graphics that improves rendering performance by decreasing the size of the data stored to or retrieved from the depth buffer when the distance from the camera to the pixel on the surface of the primitive is further than the threshold distance. The threshold distance from the camera is defined such that for such pixels the precision of a linear or quazi-linear depth buffer with a decreased data size is the same as or higher than the precision of a non-linear depth buffer with an original data size. The invention improves the usefulness of linear and quasi-linear depth buffers for 3D applications optimized for non-linear depth buffers. The present invention additionally affords a method for selecting the size of data to be read from the depth buffer before new depth values are computed for the same pixels.

    摘要: A method and system for clearing depth and color buffers in a real time graphics rendering system 10. The method and system are able to improve both depth and color buffer clearing. The method and system may utilize a frame flag, a depth clearing module, and a fast color and frame flag clearing module. The system assigns a frame flag to each pixel, which is used to determine whether the current Z value for the pixel is valid. The frame flag may be attached to Z value in the depth buffer. Instead of filling entire depth and color buffers with background values, the system only fills the holes that were not drawn in the previous frame. The fast color and frame flag clearing module traverses a rectangular area, tile by tile, where a tile is a block of pixels, to determine whether each pixel is background by checking the frame flags that are read from the depth buffer. If at least one pixel of a tile is background, the module updates those pixels' color with background color by sending requests to memory interface.

    摘要: A method of occlusion culling of graphic objects, comprising the steps of storing a first mask and one or more depth values associated with areas inside and outside the mask for a pre-defined region, and evaluating the visibility of the primitive covering the same region, wherein visibility evaluation begins after the computation of the coverage mask of the primitive in the region, and the computation of one or more depth values representing the pixels of the primitive. The method of the present invention is a real-time method of generating per-region coverage mask and associated Z values after the second primitive is rendered in the same region, which can maximize the bandwidth savings for Z read for both overlapping and non-overlapping primitives, with different relations between their depth values.
