Pixel to Mesh visualization

I have point clouds that I need to visualize, currently I use Pixel based representation in OpenGL, but I get many holes, I want to know can I generate and save data that MeshLab can open, or there is some library that works with OpenGl that can do that?

Actually I found PCL which is a great library dedicated for point cloud visualization and processing.

The process you are referring to is called surface regeneration and can a quite complex process. Although there is no builtin support for this in OpenGL, there are libraries for doing this, e.g. CGAL.

I am not familiar with MeshLab, but it seems to support many file formats e.g. PLY which should be fairly easy to output.

ply
format ascii 1.0
element vertex [SOMENUMBER]
property float x
property float y
property float z

X0 Y0 Z0
