* \ingroup PkgIsosurfacing3Ref
|
|
*
|
|
* \brief Creates a polygon soup that represents an isosurface using the marching cubes algorithm.
|
|
*
|
|
* \details
|
|
*
|
|
* \tparam ConcurrencyTag determines if the algorithm is executed sequentially or in parallel.
|
|
* \tparam Domain_ must be a model of `IsosurfacingDomain`.
|
|
* \tparam PointRange is a model of the concept `RandomAccessContainer` and `BackInsertionSequence` whose value type can
|
|
* be constructed from the point type of the polygon mesh. \tparam PolygonRange a model of the concept
|
|
* `RandomAccessContainer` and `BackInsertionSequence` whose value type is itself a model of the concepts
|
|
* `RandomAccessContainer` and `BackInsertionSequence` whose value type is `std::size_t`.
|
|
*
|
|
* \param domain the domain providing input data and its topology
|
|
* \param iso_value value of the isosurface
|
|
* \param points points making the polygons of the soup
|
|
* \param polygons each element in the vector describes a polygon using the indices of the points in points
