nm.generate(hm);
//only two normals

//both normals should be pointing at an angle more downish
Vec3f n1 = nm.get(0);

Vec3f p1(0, 1, 0);

}示例2: up

{
const int hmSize = 2;
HeightMap hm;
hm.reserve(hmSize);
for (int y=0; y<hmSize; y++)
{
for (int x=0; x<hmSize; x++)
hm.set(x, y, 0.0f);
}
NormalMap nm;
nm.generate(hm);
//there should be only two normals (since there are two triangles)
EXPECT_EQ(nm.size(), 2);
//both normals should point straight up
Vec3f n1 = nm.get(0);
Vec3f n2 = nm.get(1);

}示例3: tilable
/**Convert an image to a height map. The image is treated as grey-scale.
@param border create a height map which is larger than the source image. The source
image will be centered in the heightmap which creates a kind of border. This border
is filled with by tiling the soure image. If your source image was
created to be tilable (it ought to be) then the heightmap will be seamless. The whole
point of this is so that you can call HeightMap.blur() without ruining the seamless
nature of your heightmap. (After bluring you should ignore the border region)
