<p class="MsoNormal">The current default creaseAngle in
IndexedFaceSet is 0. The problem is that 3DS Max does not
include creaseAngle when it exports VRML or X3D. As a result
a sphere mesh would look faceted and would any other 3d mesh.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am considering our own default value for
creaseAngle to be .5 radians. Users can still override our
default value.<o:p></o:p></p>

justification for setting creaseAngle?</p>

A lot depends on how smooth you want objects to be. Since this you
are looking at models exported from Max, what does Max do when it
displays the model? I would think that you would want your default
to be as close as possible to what the artist sees during the
modeling process.<br>
