GHL 3.4.7 Release Note

This document describes contents of version up from GHL 3.4.6 to GHL 3.4.7.

Summary of this version up

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.

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. Thank you.
