Not sure if it can be done in ArcGIS 10.0 but I've got close to it...

All I'm trying to do is add a Mesh to points. The points are set out in a surface pattern (not random) much like a ball or cave, if you like. All I want to do is add a polygon skin to the point surface.

The Feature Type is 'Simple'
Geometry Type 'Point' [XYZ fields only]

The nearest I've got is through using ArcToolbox > 3D Analyst Tools > TIN Management > Create TIN

TIN's are generated but they tend to connect at a top to bottom orientation, resulting in a very spiky ball, not a hollow cavity skin. I guess I'm looking for a 3D equivalent of Delaunay triangulation between nearest points.

Can this be achieved in ArcGIS?

Is there a 3rd party software that can read 3D Point .shp files and do it?
