I can't seem to find anything on how to export 3D data in MATLAB to VRML or X3D file formats. Some posts mentioned using the vrml function, but my matlab says "vrml not found." I have both a 3 column, m*n row list of x,y,z coordinates and a mxn matrix of the z values. I'm able to save the data to a .stl file using these variables, but .stl doesn't include color info. My goal is to save this 3D data to a file that includes color info for each vertex or face, or a way to save a UV texture map so that I can print the model using Shapeways in color.

Not an answer , js comments:
1] If we can convert the 3D data to a plot3D then we have utilities in the File Exchange to convert to X3D.
2] Entire CAD models can bw imported via SIMSCAPE MULTIBODY TOOLBOX ; then converted to plot3D.
3] We want to see improvements in VR with the change in tooling from 3DAnimation to x3D.

The 'vrml' function was removed in R2014a. To use the function now, you must download it from FileExchange here:
