Create solid out of points

Hello there,

I would like to know if its possible to create a solid out of distant points or a point cloud.

Joining all points using proximity, create edges that could be perceived as a solid wireframe. Im not sure that using using 4pt surface component would be the best solution, especially when it comes to more complex point clouds. 

I thought that maybe it could be possible to create surfaces from all the points and then cull the inside surfaces to keep the outside solid shape only.

In the same idea, could it be possible to get the outline of a point cloud. 

In the current definition points 5 8 2 0 7 9 3 5, seen from top view define the outline curve of the point cloud (imagining that points have no Z value)

Thank you for your help
