Visualization of bent normals

I have visualized bent normal.

Bent normal is an average unblocked direction. It can be calculated when computing ambient occlusion.
To visualize it, I have normalized them.

This picture visualizes the original vertex normal.

And this picture visualizes the bent normal.
