From: Hane on 29 May 2010 16:27 Hi, I am trying to generate a 3D object to use in a CAD tool. The object is a cube with a random surface on top of that as one of its faces. I already generated the random surface usig surf command. I should only close the surface like a cube (vertically and horizontally) and make it 3D but I do not know HOW? I wonder if anybody has any helpful idea? Thanks, Hane

Probably your easiest way would be to use patch()

Can you please clarify it more?

Something like, XYZ = [0 0 0 1 0 0 1 0 1 1 1 1 1 1 0 0 1 0 0 1 1 0 0 1 0 0 0]; patch(XYZ(:,1), XYZ(:,2), XYZ(:,3));

I could generate a box around my random surface but I still can not merge them together to make a 3D object. Do you have any suggestion? |
