摘要： PROBLEM TO BE SOLVED: To provide a high-speed parallel processing device requiring small memory capacity by converting a graphical object into a chunk image and by synthesizing the chunk image to generate a display image. SOLUTION: In order to reduce a rendering overhead, this device executes affine transformation on a g-sprite 552 for simulating motion of a three-dimensional object rather than re-rendering the object for frame animation. Rendering geometry in a shank enables complicated fragment antialiasing. The device stores fragmentary or semitransparent pigments for expressing a partially covered pigment position in a fragment buffer. After rasterizing a primitive for the shank, a fragment decomposition auxiliary device identifies the fragment for calculating output pigments. A rasterizing component of the device tries to unite fragments for saving a fragment memory. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To lower a rendering overhead by improving a method for transforming a graphical object. SOLUTION: The system serially renders chunks of g sprites, and composites the g sprites to compute the display image. The system can perform affine transformation on g sprites to simulate motion of the 3D object rather than re-rendering the object for frame animation. Rendering geometry in the chunks enable complicated fragment list anti-aliasing. The system stores fragments representing partially covered pixel locations or translucent pixels in a fragment buffer. After rasterizing primitives for a chunk, a fragment resolution subsystem distinguishes the fragments to compute output pixels. A rasterizing component of the system attempts to merge the fragments to save fragment memory. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a low-cost, steerable, phased array antenna suitable for use in wireless fidelity and other radio telecommunications networks, in particular multi-hop ad hoc networks, and to also provide an antenna assembly that includes a plurality of linear phased array antennas fed by feed circuit. SOLUTION: The corporate feeds are implemented as parallel wire transmission lines, such as coaxials, striplines, microstrips, or coplanar waveguide (CPW) transmission lines. Selected branches of a corporate feed network include transmission line phase shifters oriented and sized so as to allow a high-permittivity dielectric element to control phase shifting. Thus, the feed circuit forms a phase shifting feed, whose phase shift is controllable. Phase shifting can be controlled electromechanically, by controlling the space between the high-permittivity dielectric element and the phase shifting branches of the corporate feed, or by electrically controlling the permittivity of the high-permittivity dielectric element.

摘要： To render a display image, the system serially renders chunks of the gsprites, and composites the gsprites to compute a display image. To reduce rendering overhead, the system can perform affine transformations on gsprites to simulate the motion of a 3D object rather that re-rendering the object for frames animation. Rendering geometry in chunks enables sophisticated fragment list anti-aliasing. The system stores fragments representing partially covered pixel locations or translucent pixels in a fragment buffer. After rasterizing primitives for a chunk, a fragment resolution subsystem resolves the fragments to compute output pixels. The rasterizing component of the system attempts to merge fragments to save fragment memory. If the fragment memory is exceeded, the system can subdivide chunks into smaller regions and render these smaller regions independently. The system supports texture accessed in environments with high latency such as in cases where texture data is compressed. The latency of texture accessing is reduced using either a texture reference or "pixel queue" to buffer partially rendered pixel data as texture data is fetched from memory, or using a pre-rasterizer to generate texture requests and a post-rasterizer to rasterize primitives completely using texture data fetched as a result of the texture requests generated by the pre-rasterizer. The system support anisotropic filtering of texture data by repetitively sampling texture data along a line of anisotropy computed for pixel location mapped into a texture or MIP mapped textures.
摘要翻译：为了呈现显示图像，系统连续渲染gsprites的块，并复合gsprites来计算显示图像。为了减少渲染开销，系统可以在gsprites上执行仿射变换来模拟3D对象的运动，而不是重新渲染对象进行帧动画。以块形式呈现几何，可实现复杂的片段列表抗锯齿。系统将代表部分覆盖的像素位置或半透明像素的片段存储在片段缓冲器中。光栅化图块中的图元后，片段解析子系统可以分解片段以计算输出像素。系统的光栅化组件尝试合并片段以保存片段内存。如果超过了碎片存储器，系统可以将块细分为更小的区域，并独立地渲染这些较小的区域。该系统支持在具有高延迟的环境中访问的纹理，例如在纹理数据被压缩的情况下。使用纹理参考或“像素队列”来缓冲部分渲染的像素数据，因为纹理数据是从存储器中获取的，或者使用预光栅化器来生成纹理请求，而后光栅化器完全光栅化图元使用由预光栅器生成的纹理请求的结果获取的纹理数据。该系统通过沿映射到纹理或MIP映射纹理的像素位置计算的各向异性线重复采样纹理数据来支持纹理数据的各向异性过滤。
