Thank you Bruce. I can load it as patch as you suggested. I can also load the curvatures to color it. Thus I imagine in the data, there would be 2D locations of the vertices, and their indices respect to the full surface. Is it true? How can I read this information (e.g. into matlab) ? Thanks again! Also thanks to anyone who would like to comment!
