STLWRITE Write STL file from patch or surface data.

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 triangulation 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 chars) 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 quads b - Back slash division of quadrilaterals x - Cross division of quadrilaterals Note that f, b, or t triangulations now use an inbuilt version of FEX entry 28327, "mesh2tri".

FACECOLOR - Single colour (1-by-3) or one-colour-per-face (N-by-3) vector of RGB colours, for face/vertex input. RGB range is 5 bits (0:31), stored in VisCAM/SolidView format (http://en.wikipedia.org/wiki/STL_(file_format)#Color_in_binary_STL)

Example 1

Write binary STL from face/vertex data Empty voxel volume Turn some voxels on Make patch w. faces "out" Save to binary .stl

Example 2

Write ascii STL from gridded data Create grid reference Create grid height stlwrite(test.stl,X,Y,Z,mode,ascii)

Example 3

Write binary STL with coloured faces Colour by Z height. Transform height values onto an 8-bit colour map fColsDbl = interp1(linspace(cLims(1),cLims(2),nCols),cMap,cVals); Pass cols in 8bit (0-255) RGB triplets stlwrite(testCol.stl,fv,FaceColor,fCols8bit)
