摘要： A distributed clipping scheme is provided, view frustum culling is distributed in several places in a graphics processing pipeline to simplify hardware implementation and improve performance. In general, many 3D objects are outside viewing frustum. In one embodiment, clipping is performed on these objects with a simple algorithm in the PA module, such as near Z clipping, trivial rejection and trivial acceptance. In one embodiment, the SE and RA modules perform the rest of clipping, such as X, Y and far Z clipping. In one embodiment, the SE module performs clipping by way of computing a initial point of rasterization. In one embodiment, the RA module performs clipping by way of conducting the rendering step of the rasterization process. This approach distributes the complexity in the graphics processing pipeline and makes the design simpler and faster, therefore design complexity, cost and performance may all be improved in hardware implementation.
摘要翻译：提供了一种分布式剪裁方案，视图平滑截尾分布在图形处理流水线的多个位置，以简化硬件实现并提高性能。一般来说，许多3D对象都在观察截面外。在一个实施例中，使用PA模块中的简单算法对这些对象进行限幅，例如接近Z限幅，平凡的拒绝和微不足道的接受。在一个实施例中，SE和RA模块执行其余的剪辑，例如X，Y和远Z限幅。在一个实施例中，SE模块通过计算光栅化的初始点来执行削波。在一个实施例中，RA模块通过进行光栅化处理的渲染步骤来执行裁剪。这种方法在图形处理流水线中分配复杂性，使设计更加简单快捷，因此硬件实现中的设计复杂性，成本和性能都可能得到改善。

摘要： A hierarchical tile-based rasterization method is disclosed. The inventive rasterization algorithm rasterizes pixels in hierarchical rectangles or blocks. The method includes: walking a plurality of tiles of pixels and determining if each tile is valid; breaking each valid tile into a plurality of subtiles and determining if each subtile is valid; breaking each valid subtile into a plurality of quads and determining if each quad is valid; and rendering pixels for each valid quad. These hierarchical levels of block validations are performed in parallel. The inventive rasterization algorithm is further implemented in hardware for better performance.

摘要： An apparatus and method to dynamically regulate system bandwidth in a graphics system includes receiving vertex data from an application by way of an application programming interface. The rate that the vertex data is received from the application is then determined. In the event the rate is greater than a selected threshold, the graphics system is configured to operate in immediate mode, wherein vertex data is rendered immediately upon reception. In the event the rate is less than the selected threshold, the graphics system is configured to operate in retained mode, wherein vertex data is stored prior to being rendered. The apparatus and method switches between each of the modes on-the-fly in a manner that is transparent to the application.

摘要： An apparatus and method for rasterizing a primitive in a graphics system is disclosed in one example of the invention as including scanning a first row of tiles, one tile at a time, starting from a first point and scanning in a first direction. Immediately after scanning the first row of tiles, the method includes moving from the first point to a second point in an orthogonal direction relative to the first row. Immediately after moving from the first point to the second point, the method includes scanning a second row of tiles, one tile at a time, starting from the second point and scanning in the first direction. By scanning rows in the same direction immediately prior to and after moving from one row to another, cache utilization is improved.
