auto SFCGAL::algorithm::ConsistentOrientationBuilder::buildTriangulatedSurface

(

)

Get the resulting TriangulatedSurface where each connected part has consistent orientation.

Returns

TriangulatedSurface with consistent orientation

Exceptions

SFCGAL::Exception

if such a TriangulatedSurface can't be built

const std::set<size_t>& SFCGAL::algorithm::ConsistentOrientationBuilder::neighbors

(

const size_t &

n

)

const
