And this difference may be induced by the nonlinear function of piecewise-smooth map.

这个差异可能由分段光滑映象函数的非线性造成。

A heat map shows where to expect trouble in a system and where to expect smooth sailing.

The level is clear, the carving is smooth, the decoration is exquisite, the time style is obvious, the abdomen draws the character story map, the pattern cloth.

So, this approach requires one more layer of effort: converting the height map (or at least its visible tiles) into a "normal map" which is smooth and natural enough to be subjected to lighting effects and then displayed on screen.

The first filter that is applied to the height map is a simple Gaussian blur, which the GPU handles with ease, but which -- if left to its own devices -- would simply smooth out all the dramatic extremes in the height map and leave us with a bunch of bland rolling hills.
