如何将高度图绘制到屏幕上？
我正在使用 DirectX10 来模拟水面，现在我有了一个高度图，它是点 (x,z) 处高度 (y) 的二维数组。但要将其绘制在屏幕上，我必须将其变成网格或有一个索引来绘制三角形拓扑。
但数据太大，无法手动完成。有什么方法可以让我把它画在屏幕上吗？我希望它很容易实现。如果 DirectX10 中包含的功能可以做到这一点，那么它对我来说是最好的。
I'm using DirectX10 to simulate a water surface, and I'm now with a height map,which is a 2D array of the heights(y) at the points (x,z). But to draw it on the screen, I must turn it into a mesh or have a index to draw triangle topology.
But the data is too large to do it manually. Are there any methods for me to draw it on the screen. I hope it's easy to implement. If there is function included in DirectX10 which can make it, the it's the best one for me.

创建一个网格，格式化正方形网格（每个网格由两个三角形组成）并设置所有顶点y = 0。在顶点着色器中对高度图进行采样，并将存储在高度图中的值添加到顶点的y。
这可能对你有帮助。
PS：如果你想要它覆盖的区域太大，你应该采取了解地形 LOD 技术（对于水应该同样有效）。
Create a mesh that format a grid of squares (each made of two triangles) and set all vertices y = 0. In the vertex shader sample the heightmap and add the value stored in the heightmap to the y of the vertice.
This might help you.
P.S: If the area you want it to cover is too big you should take a look at terrain LOD techniques (should work the same for water).
我相信你可以用它制作一个网格。我怀疑您是否可以为太大而无法“网格化”的水面生成高度图。
你为什么看钻石广场？对于 512x512 高度图，您所需要做的就是定义一组点，然后为其生成三角形。它真的非常简单。
I'm sure you can make a mesh out of it. I doubt you can generate the heightmap for a water surface that is too large to "meshify".
Why are you looking at Diamond square. For a 512x512 heightmap all you need to do is define a set of point and then generate the triangles for it. Its really very simple.
