I have 3D data point as [x,y,z] matrix which show a geometry in 3D such as cube, sphere, any complex geometry...I want to show this geometry as closed surface, but unfortunately, 3D visualization in Matlab such as mesh, surfc... can not do it. > > So, anybody help me to do above problem. > > Thank you in advance. > > You might find something here that does what you need: > http://www.advancedmcode.org/
The simplest real solution is the convex hull, convhulln() in Matlab. This probably won't give you any "complex geometry", depending on what you mean by that.
