EgtGeomKernel/CurveBezier.h
T
Dario Sassi bab45eb4f3 EgtGeomKernel 1.6h3 : 
- migliorata approssimazione curve per riconoscimento di tratti rettilinei
- aggiunta CopyMaterial a GeomDB
- correzioni a IntersCurveCurve per le curve approssimate
- aggiunte a Intervals Union, Intersection e Difference
- correzioni a SelfIntersCurve per curve approssimate
- aggiunte funzioni di creazione Regioni (Rectangle, Stadium, Disk e da zuppa di curve)
- migliorie varie a Regioni e introduzione dei componenti connessi (chunk).
