I want to know whether this normal map i created is correct.. I was expecting where the object is planar, it should have pure blue color, no component of red or green color… But clearly this is not pure blue. I created this using 3DS autodesk 2011
Yes it looks ok. Since the components of the normal is in the range
[-1, 1]they need to be remapped to[0, 255]before they can be stored in the normal map. This is done by:For a normal of
[0 1 0]you get a value of[128 255 128].
