Write STL file from surface data.

Editor's Notes:

This file was selected as MATLAB Central Pick of the Week

File Information
Description	SURF2STL Write STL file from surface data. SURF2STL('filename',X,Y,Z) writes a stereolithography (STL) file for a surface with geometry defined by three matrix arguments, X, Y and Z. X, Y and Z must be two-dimensional arrays with the same size. SURF2STL('filename',x,y,Z), uses two vector arguments replacing the first two matrix arguments, which must have length(x) = n and length(y) = m where [m,n] = size(Z). Note that x corresponds to the columns of Z and y corresponds to the rows. SURF2STL('filename',dx,dy,Z) uses scalar values of dx and dy to specify the x and y spacing between grid points. SURF2STL(...,'mode') may be used to specify the output format. 'binary' - writes in STL binary format (default) 'ascii' - writes in STL ASCII format Example: surf2stl('test.stl',1,1,peaks); See also SURF. Author: Bill McDonald, 02-20-04

07 Mar 2006	Mike M	Has good nift. Use with gridgen to make mathematical surfaces into stl files for cfd. mmmm
03 Oct 2007	Amanda L	very neat. Used for converting small pieces of scarcely digitized bone surface point clouds to STL surface which can be loaded into Mimics and Amira.
20 Feb 2008	Yoel Shapiro	Very helpfull! I tried for a long time to open a MATLAB generated mesh or vrml in different 3D environments and couldn't. This did the job.
25 Jul 2008	Max Lingamfelter	Very nice program. Does anyone know a way to write the STL file while keeping other data intact to describe the color? maxami13@msn.com
19 Aug 2008	Bin Huang	Awesome! It helps me alot.
28 Jan 2009	Daniel Lopes	Thanks Bill! You made a very useful MATLAB function for geometric modeling purposes. Woks just fine!
02 Mar 2009	Bart Ribbens	Great job! Thanx a lot!
18 May 2009	Zoltan	Nice! But you could speed it up - it counts at large meshes, if you could find a way to avoid the for loop. For calculating the surface normals, you could use "surfnorm". Thanks!
