GHL 3.4.8 patch 01 Release Note

This document describes about the contents of patch 01 for GHL 3.4.8.

• Added functions
• Fixed bugs

Added functions

Functions: [2D] gh2jdgwCLsg2()

gh2jdgwCLsg2() is a version of gh2jdgwCLsg() to ignore small self-intersections.

Functions: [2D] gh2jdgwCCmc2()

gh2jdgwCCmc2() is a version of gh2jdgwCCmc() to ignore small self-intersections.

Fixed bugs

Functions: [3D] gh3intsSTriSTri()

The process of connecting line-segments from each pair of two triangle sets fails, if the end point of a line-segment is on the boundaries of both triangles.

Functions: [2D] gh2smlpCCmc() gh2smlpCCmc2()

If the given offsetted curve has an overlapped section, some valid divided loops are not judged correctly and returned as 'Gh_TfuUndef'.

Functions: [2D] gh2intfTrcTrc()

If two circular arcs contact with each other at the point of parameter 0 (parameter 2 pi), an incorrect overlap section is returned instead of an intersection.

Functions: [2D] gh2sop[sc]CCmcCCmc(), gh2sop[sc]PlgPlg()

If the given two curves intersect each other tangentially, the correct solutions are not returned.

Functions: [2D] gh2lengCmc()

If the given '*pint's 'increase' is negative, the function does not return correct solutions,

Functions: [3D] gh3lengCmc()

If the given '*pint's 'increase' is negative, the function does not return correct solutions,

Functions: [2D] gh2sop[sc]CCmcCCmc(), gh2sop[sc]PlgPlg()

If the given two curves have overlapping sections, incorrect open curves are returned.

Functions: [2D] gh2norm???Cmc(), gh2norm???Trc(), gh2tang???Cmc(), gh2tang???Trc()

Some memory leaks.

Functions: [3D] gh3lengCmc()

The function returns an incorrect value for closed curves, if the whole 'pint' with non-zero starting parameter is given.

Functions: [2D] gh2lengCmc()

The function returns an incorrect value for closed curves, if the whole 'pint' with non-zero starting parameter is given.

Functions: [2D] gh2convCmcLsg()

The function does not return the correct solution for a closed composite curve with a parameter which is out of the primary parameter domain.

Functions: [3D] gh3convCmcLsg()

The function does not return the correct solution for a closed composite curve with a parameter which is out of the primary parameter domain.

Functions: [2D] gh2convCirLsg()

There is no consideration for the case that the given circle's radius is less than or equal to 'tol'.

Functions: [2D] gh2ofstCmcCmcByBzc2(), gh2ofstCmcCmc2ByBzc2(),

There is a case that the functions trim offset sections which should be remained.

Files: [2D] gh2evalBsc.c gh2evalBzc.c gh2evalRsc.c gh2evalRzc.c

Fixed some mis-editting which causes some compilers to make a warning about referring return values from void gh2leng???().

Files: [3D] gh3evalBsc.c gh3evalBzc.c gh3evalRsc.c gh3evalRzc.c

Fixed some mis-editting which causes some compilers to make a warning about referring return values from void gh3leng???().

Files: [TEST/YBS] ybs_define_{cbs,les,rts,rvs,trc}.c

some memory leaks.
