Outputing a Colormap for 3D printing

Hi,

I am wondering if anyone knows of a way to output the colour map from a 3D plot (such as surf() or mesh()) so it can be converted used as a colour file for a VRML97 or X3D file.

I have a 3D plot that I want to 3D print and I have been able to successfully output a .stl file with the help of surf2solid and stlwrite, but I would like to be able to print the surface colour using shapeways colour ceramic service.

Anyhelp or pointers in the right direction would be appreciated.

Hi Scott,

do you have any update on this matter? I'm facing the same problem ;)

Thanks Luca

You can get the colormap from the figure and then the CData from the surface:

fig = figure;
s = surf(peaks);
cmap = fig.Colormap;
cdata = s.CData;

Now each index in cdata points to the color in that row of cmap.
