I found a solution to create PDFs with rotatable 3D graphs from MATLAB without LaTeX. I am using R2012b with Mac OS 10.8.2. You don't need any additional toolboxes.
Kind regards, Martin
1. Create 3D Graph and export it with the (hidden) function VRML to create a VRML/WRL file.
[X,Y] = meshgrid(-8:.5:8); R = sqrt(X.^2 + Y.^2) + eps; Z = sin(R)./R; surf(Z); vrml(gcf,'myexample.wrl')
2. Use the free software MESHLAB to import the VRML/WLR file. Export the graph as 3DS File.
3. Use the free software BLENDER to import the 3DS file. Select the CUBE in the right panel, open the CUBE directory by selecting the PLUS sign, select CUBE, then REMOVE VERTICES in the left panel of the user interface. Export the result as COLLADA DAE file.
4. Use the free software GOOGLE SKETCHUP to import the DAE file. Unfortunately you now need the commercial plugin SimLab PDF Exporter ($99) to create the PDF file. Don't modify the settings of the plugin, it just works fine as it is. You can use a trial before you buy it.
5. Open the PDF file in Acrobat. Use the Model Rendering Mode to modify the appearance of the 3D graph, e.g. hide/unhide mesh, control transparency, light etc.
