stlwrite - Write binary or ascii STL file 1.0

STLWRITE(FILE,fv) writes a stereolithography (STL) file to FILE for a triangulated patch defined by FV (a structure with fields 'vertices' and 'faces'). STLWRITE(FILE,FACES,VERTICES) takes faces and vertices separately, rather than in an FV struct STLWRITE(FILE,X,Y,Z) creates an STL file from surface data in X, Y, and Z. STLWRITE triangulates this gridded data into a triangulated surface using triangulations options specified below. X, Y and Z can be two-dimensional arrays with the same size. If X and Y are vectors with length equal to SIZE(Z,2) and SIZE(Z,1), respectively, they are passed through MESHGRID to create gridded data. If X or Y are scalar values, they are used to specify the X and Y spacing between grid points. STLWRITE(...,'PropertyName',VALUE,'PropertyName',VALUE,...) writes an STL file using the following property values: MODE - File is written using 'binary' (default) or 'ascii'. TITLE - Header text (max 80 characters) written to the STL file. TRIANGULATION - When used with gridded data, TRIANGULATION is either: 'delaunay' - (default) Delaunay triangulation of X, Y 'f' - Forward slash division of grid quadrilaterals 'b' - Back slash division of quadrilaterals 'x' - Cross division of quadrilaterals Note that 'f', 'b', or 't' triangulations require FEX entry 28327, "mesh2tri". FACECOLOR - (not currently implemented) When used with face/vertex input, specifies the colour of each triangle face. If users request this feature, I will attempt to implement it. Example 1: % Write binary STL from face/vertex data tmpvol = zeros(20,20,20); % Empty voxel volume tmpvol(8:12,8:12,5:15) = 1; % Turn some voxels on fv = isosurface(tmpvol, 0.99); % Create the patch object stlwrite('test.stl',fv) % Save to binary .stl Example 2: % Write ascii STL from gridded data [X,Y] = deal(1:40); % Create grid reference Z = peaks(40); % Create grid height stlwrite('test.stl',X,Y,Z,'mode','ascii') Original idea adapted from surf2stl by Bill McDonald. Non-Delaunay triangulation of quadrilateral surface input requires mesh2tri by Kevin Moerman.Note: This entry was originally titled "patch2stl", however has been renamed to "stlwrite" after more general input was added.
