...构 其可编程性主要体现在两个方面 一 是以向量为基础的可编程顶点着色器 它通过用 户编制的向量运算顶点处理程序(Vertex Program) 实现顶点由物体空间到屏幕空间的变 换和顶点光照计算 二是以像素和纹理处理为基 础的4 级层次化纹理绘制机制和8 级层次化寄存 器...

可编程图形处理器允许用户编写运行在其上的顶点着色程序与片断着色程序,取代内置的固定功能渲染流水线,实现定制的渲染算法。
The programmable GPU permits developers to write vertex shaders and fragment shaders running on it, to replace the fixed function pipeline, and to employ custom rendering algorithms.
注意,图形硬件处理在的实际的顶点数,3D程序中显示的通常是不一样的。
Note that the actual number of vertices that graphics hardware has to process is usually not the same as displayed in a 3D application.
请注意,图形硬件处理顶点的实际数量通常和3d应用程序显示的不一样。
