示例1: minkowskiSum
void minkowskiSum( const LineString& gA, const Polygon_2& gB, Polygon_set_2& polygonSet )
{
if ( gA.isEmpty() ) {
return ;
}
int npt = gA.numPoints() ;
for ( int i = 0; i < npt - 1 ; i++ ) {
Polygon_2 P;
P.push_back( gA.pointN( i ).toPoint_2() );
P.push_back( gA.pointN( i+1 ).toPoint_2() );
//
// We want to compute the "minkowski sum" on each segment of the line string
// This is not very well defined. But it appears CGAL supports it.
// However we must use the explicit "full convolution" method for that particular case in CGAL >= 4.7
#if CGAL_VERSION_NR < 1040701000 // version 4.7
Polygon_with_holes_2 part = minkowski_sum_2( P, gB );
#else
Polygon_with_holes_2 part = minkowski_sum_by_full_convolution_2( P, gB );
#endif
// merge into a polygon set
if ( polygonSet.is_empty() ) {
polygonSet.insert( part );
}
else {
polygonSet.join( part );
}
