My Parallax Mapping is not performing as what it should, I am taking the images from the SDK Demo, which is the wood and the shapes heightmap.

Here is the image of what it turn out to be: The image seems warped. Is there anything wrong with my HLSL code? Sorry for the long post

It's difficult to say from just static code analysis what your problem is, but I have seen similar results when I implemented POM last year. It tends to be a simple case of flipping the sign/direction of a ray or vector that you're using - you'll probably find you're tracing in the wrong direction or offsetting in the wrong direction...

It can take a while to work it through from the theory, but there are lots of POM/RM samples online you can use as references. See how they're doing it and see if there are any obvious differences. Start with the SDK implementation.
