Anybody know how to convert a Matlab surface plot to something usable by Shapeways? I have this Matlab script that creates an object using the surface function. Is there any way to save that in some usable form?
Export the original 2d matrix from Matlab as an Image (PNG is good; I think it'll allow a higher bit depth for detail). Apply this image as a height-map or height-field in your 3d application, then extrude along normals for thickness (or, if flat enough, simply along the Y axis).
If you need more detail, I can expand, but probably only for Blender use.
