For some reason two polygons (one in the x-y-plane and one in the x-z-plane) are rendered as a polygons with 4 points although they contain 5 points.<br>

When I generated the data set there were some duplicated vertices, i.e. vertices with identical coordinates but different index and only one of the polygons was rendered incorrectly. I eliminated the duplicates and the second polygon was rendered incorrectly. I have no idea if that helps.<br>
