I am trying to generate triangular mesh from point clouds obtained by Terrestrial Laser Scanners. I use marching cubes algorithm of VTK library. When I visualize the generated mesh it seems as a thick surface as shown in the image below:

Could you please help me about this problem? I want to generate meshes as shown in the second figure.
I am looking forward to hearing from you
