如何由Height Map生成Normal Map Nvidia和ATI都有相应的工具把Heightmap转成NormalMap,有了NormalMap,我们就可以用NormalMapping技术进行Per Pixel Lighting计算了。那么HeightMap是怎么转化成NormalMap的呢? 其实并不难,在《3D游戏与计算机图形学方法》中,提供了一种由高度图生成法向图的方法。其思想是根据高度图中的...

现代的 normal map，又称为 normal perturbation map，应该是沿自 [2] 。

一般来说,NormalMap来自于HeightMap。具体生成的方法如下: 把HeightMap的每个像素和它上面的一个像素相减,得到一个高度差,作为该点法线的x值; 把HeightMap的每个像素和它右边的一个像素相减,得到一个高度差,作为该点法线的y值; 取1作为该点法线的z值。
Normal map (Bump mapping) Occlusion Map HeightmapHeight mapping (also known as parallax mapping) is a similar concept to normal mapping, however this technique is more complex - and therefore also more performance-expensive. Heightmaps are usually used in conjunction with normalmaps, and often ...
When working with displacement in mind, is it still a good idea to generate normal maps from the height map? It seems like when that is done, the normal map does weird things on top of the displaced geometry at render time. Looking for some gidance where this is con...
