You can use fixed - point vertex data to increase the transforming and lighting speeds of 3d graphics drivers that do not implement transforming and lighting in hardware 您可以使用定点顶点数据来提高那些未在硬件中实现几何形变和光效处理的三维图形驱动程序的几何形变和光效处理速度。
Applies the vertex processing defined by the vertex shader to the set of input data streams , generating a single stream of interleaved vertex data to the destination vertex buffer 将顶点着色器定义的顶点处理过程应用到输入数据流组，从而生成从插入的顶点数据到目标顶点缓冲区的单个流。
In chapter 2 , we discuss the terrain modeling with continuous level of detail , described a data layout technique for manage out - of - core datasets . then , we investigate the opengl based nv extension for fully taking advantage of the accelerating function of graphic hardware and improving the capability of rendering 该框架还有效地利用了nvidia的opengl扩展gl _ nv _ vertex _ array _ range和gl _ nv _ fence来对场景的渲染进行加速。它们能够让几何图形高效地传输到gpu ， gpu直接访问顶点数据，使得应用程序的执行效率极大提高。
In chapter 3 , for the case that the terrain data can not fit in memory , we describe a data layout technique of providing coherent access to the terrain data that are consistent with our mesh simplification . we reorder the data in a manner that is of multiresolution and the overhead is completely eliminated 第三章中，为了能处理超出内存容量的地形数据，我们对海量地形数据进行了重新组织，设计了一种基于层次二叉树的遍历方式的顶点存储方式，存储的顶点数据是多分辨率组织的，并且没有冗余。
