Maybe I have to be a bit clearer with my problem.

OK how you can see I have my terrain with the shader you can see above, but it's very hard to find out whether there is a hill or not!


So if you look to the picture for a couple of time you will find the hill but it's of course much to difficult.


So perhaps somebody has another idea how to fix this problem, but my first idea was Gouraud Shading.

I hope somebody know what I mean and is be able to help me.

Thanks
