Did you figure this out yet?

Exporting the patch h without color information is no problem:

verts = get(h,'Vertices');
v = sprintf('vertex_vectors {\n%i,\n', size(verts,1));
v = [v sprintf('<%f, %f, %f>,\n', verts')];
v = v(1:end-2);
v = [v sprintf('\n}\n')];

norms = get(h,'VertexNormals');
n = sprintf('normal_vectors {\n%i,\n', size(norms,1));
n = [n sprintf('<%f, %f, %f>,\n', norms')];
n = n(1:end-2);
n = [n sprintf('\n}\n')];

faces = get(h,'Faces');
f = sprintf('face_indices {\n%i,\n', size(faces,1));
f = [f sprintf('<%i, %i, %i>,\n', faces'-1)];
f = f(1:end-2);
f = [f sprintf('\n}\n')];

povray = [sprintf('mesh2 {\n') v n f sprintf('}\n')];

However, I haven't found a good way to export the colors of the vertices.
Povray supports color per vertex in the mesh2 object. However, it seems to support only indexed color...
