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.

added functions

gh3diviSTri	divides a set of triangles with arbitrary curves

List of fixed bugs

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.
