X slice contour polygons were traced from 3D data array, so all endpoints of the polygons have same x coordinates. In this situation, tessellation result looks blurred and some polygons were not filled correctly. Please see the figure below.


I tried to add random small value to x coordinates fo each endpoint, so the x coordinate values are not all same. Then the tessellation result looks correct.


I am not sure if it's a bug or not.
