这是因为团队将在不同的时间点生成不同详细级别的各种工作产品。

This is because the teams will be producing various work products to differing levels of detail at different points in time.

上图是通过简单地把CPU和磁盘使用率指定为线并把每个应用程序的二进制焦点数据指定为点生成的。

The graph above is generated by specifying the CPU and disk usage as lines and the binary focus data per application as dots only.

它使用LOD系统，当然，因为摄像机会不停地移动焦点，地形也需要不断的根据焦重新点生成三角形。

It USES a linear LOD system, and, of course, because when the camera moves away from the focal point, the terrain needs to be regenerated to 'focus' on the new focal point.

And we can just extrapolate in a straight line We before saw some examples where I had an algorithm to generate points, and we fit a curve to it, used the curve to predict future points and discovered it was nowhere close.

我们可以干脆用一条直线来描述它,我们之前看到在一些例子中,我用一个算法去生成一些点，然后用一条曲线对它进行拟合，然后用这条曲线来预测未来的点,最后却发现结果完全不对。
