IPC分类号： G06T15/00
摘要： A graphics pipeline includes a plurality of sequentially arranged processing stages which render display pixel data from input primitive object data. The processing stages include at least a texturing stage and a depth test stage, and the depth test stage may be located earlier in the graphics pipeline than the texturing stage.

摘要： This disclosure describes an apparatus, such as a wireless communication device, that applies a direct evaluation technique to render triangles for the 3D graphical environment. The apparatus includes a rendering engine that defines a rectangular area of pixels, referred to as a bounding box, that bounds the area to be rendered. The rendering engine evaluates coordinates associated with the pixels of the rectangular area to selectively render those pixels that fall within the triangular area. The direct evaluation triangle rendering algorithm may require fewer complex operations than the more computationally intensive interpolation process employed by other systems. As a result, the apparatus may present a 3D graphical environment while preserving as much as possible the available power.
摘要翻译：本公开描述了一种诸如无线通信设备的装置，其应用直接评估技术来渲染3D图形环境的三角形。该装置包括描绘引擎，该引擎定义了限定要渲染的区域的被称为边界框的像素的矩形区域。渲染引擎评估与矩形区域的像素相关联的坐标，以选择性地渲染落在三角形区域内的像素。直接评估三角形渲染算法可能需要比其他系统使用的计算密集型插值过程更少的复杂操作。结果，该装置可以呈现3D图形环境，同时尽可能多地保留可用功率。

摘要： In general, the invention is directed toward a device for processing digital video data, such as an encoder, a decoder or an encoder/decoder (CODEC). The device makes use of an innovative architecture in which functionality is partitioned between an embedded processor, a digital signal processor and dedicated hardware to achieve increased performance. In addition, the device includes a programmable video direct memory access (VDMA) controller to retrieve video data from memory in response to a command specifying a multidimensional block of video data.
