This code works well for MATLAB 7.0 but it is important that the wrl file defines each vertex and polygon on a new line; otherwise some vertices and polygons will be ignored! Confirm this by opening the wrl file in the MATLAB editor. In addition, I found that it may be necessary to modify the h file generation as follows (i.e. excluding the file extensions):

%Generate h-file (handle pointing to) the mfile
hReadVRML20 = @ReadVRML20;

%Save h-file to Current Directory
save hReadVRML20.h hReadVRML20;
loadlibrary('ReadVRML2_0','hReadVRML20');
chk = libisloaded('ReadVRML2_0');

if chk
    disp('The dll loaded successfully')
else
    disp('The dll was not loaded successfully')
end

%Now able to call the ReadVRML20(vrml_fn) m-file
o = ReadVRML20('my_file.wrl');

% plot the 3D world
x = o.Vertex(1,:);
y = o. Vertex (2,:);
z = o. Vertex (3,:);
tri = o.Face';
trimesh(tri,x,y,z,'edgecolor','black');

% Unload the library (after use) and free up the memory
unloadlibrary ReadVRML2_0

This would be great, except is there a header file that should be included? How do I load a .dll ?
