GHL 3.4.7 Release Note
This document describes contents of version up from
GHL 3.4.6 to GHL 3.4.7.
 2D: Expansion of offsetting composite curves

Type 2 and 3 functions
of offsetting composite curves have been expanded
to search the intersection for trimming among several other offset curves a
little far from the target, not only the adjacent one.
 3D: A function to divide a set of triangles with arbitrary curves

A fucntion
to divide a set of triangles has been added.
This function divides the given set of triangles with the intersectional curves
obtained from
the
function
to find intersections between a set of triangles and a plane or
the
function
to find intersections between two sets of triangles.
3D
gh3diviSTri divides a set of triangles with arbitrary curves
Following bugs have been fixed after the release of GHL 3.4.6.
 gh3convCbsSTri_Rev2, gh3convCbsSTri2_Rev2
 had happened to kill the process at a particular situation.
 gh3sdst{Crv,Srf}{Crv,Srf}
 had not returned the correct answers for periodic geometry elements.
 gh3sdstCrv{Crv,Srf}
 had not returned the correct answers for relatively small curves.
 gh[23]incdBsc2, gh[23]incdRBsc2, gh3incdBss2, gh3incdRBss2
 had not returned the correct answers if the given Bspline curve/surface
had some slightly different knots at the end of its domain.
We greatly appreciate bug reports from GHL users.
