Summary0022318: Regression (since OCCT 6.3.1): bad shading of small cylinder (forum thread 20083)
DescriptionThe problem is reported on OCC Forum thread 20083:
http://www.opencascade.org/org/forum/thread_20083

In OCCT 6.5.0, if compound consisting of small and big cylinders is displayed in
shading mode (not in wireframe first!), mesh on small cylinder is very rough.

New features:
No
Improvements:
The triangulation of small cylinder builds right now.
Changes:
The triangulator takes into account the type of edge. If it has a circle-like
type a number of vertices may be more than two.
Modified entities:
Package BRepMesh: BRepMesh_FastDiscret.cxx (BRepMesh_FastDiscret.cdl) - small
code change
