<a href="a14534.html">List of all members.</a><hr><a name="_details"></a><h2>Detailed Description</h2>
Objects that compute geometry-based error during cell tessellation according to some max angle.
<p>
It is a concrete error metric, based on a geometric criterium: a max angle between the chord passing through the midpoint and one of the endpoints and the other chord passing through the midpoint and the other endpoint of the edge. It is related to the flatness of an edge.<p>

Set the flatness threshold with an angle in degrees. Internally compute the cosine. value is supposed to be in ]90,180[, if not it is clamped in [90.1,179.9]. For instance 178 will give better result than 150.

Does the edge need to be subdivided according to the cosine between the two chords passing through the mid-point and the endpoints? The edge is defined by its `leftPoint' and its `rightPoint'. `leftPoint', `midPoint' and `rightPoint' have to be initialized before calling <a class="el" href="a01565.html#dc341b2d2532a280a49105a73384e3ff">RequiresEdgeSubdivision()</a>.
