Instead of defining lines, this file defines faces (small surfaces), each by 3 (triangle) to 6 (hexagon) points. The points must be ordered to trace a path going around the face. For proper rendering, the faces should have consistent point ordering, either clockwise or counterclockwise. Each face is automatically closed by connecting the last point to the first point. Face connectivity data is listed in the&nbsp;<code class=\"code codeInline\" spellcheck=\"false\">Faces<\/code>&nbsp;section and references the points in the&nbsp;<code class=\"code codeInline\" spellcheck=\"false\">Data<\/code>&nbsp;section, where the latter are implicitly numbered, starting with 0.<\/p>\n<p><\/p>\n<\/p>\n<p>&quot;&quot;&quot;<\/p>\n<p>I am not able to understand the data format for Faces section.
