I am trying to make a terrain engine and thus, I must retrieve the height values from the bitmap. This is my current code:

D3DLOCKED_RECT rect;

tex->LockRect(0, &rect, NULL, 0);
    if (rect.pBits)
        land.HeightField = (BYTE*)rect.pBits; //the HeightField is type BYTE*

    tex->UnlockRect(0);
 

My texture is created with D3DPOOL_MANAGED and 0 for usage. Now that I have my data, How should I make a list of the heights? Thanks

Drunken Hyena (www.drunkenhyena.com) has code that does this, as far as I recall. Take a look at it.
