Detailed Description

template<int dim, int spacedim>
class OpenCASCADE::DirectionalProjectionManifold< dim, spacedim >

A Manifold object based on OpenCASCADE TopoDS_Shape where new points are first computed by averaging the surrounding points in the same way as FlatManifold does, and then projecting them onto the manifold along the direction specified at construction time using OpenCASCADE utilities.

This class makes no assumptions on the shape you pass to it, and the topological dimension of the Manifold is inferred from the TopoDS_Shape itself. In debug mode there is a sanity check to make sure that the surrounding points (the ones used in project_to_manifold()) actually live on the Manifold, i.e., calling OpenCASCADE::closest_point() on those points leaves them untouched. If this is not the case, an ExcPointNotOnManifold is thrown.

Notice that this type of Manifold descriptor may fail to give results if the triangulation to be refined is close to the boundary of the given TopoDS_Shape, or when the direction you use at construction time does not intersect the shape. An exception is thrown when this happens.

◆ DirectionalProjectionManifold()

template<int dim, int spacedim>
OpenCASCADE::DirectionalProjectionManifold< dim, spacedim >::DirectionalProjectionManifold ( const TopoDS_Shape &  sh,
const Tensor< 1, spacedim > &  direction,
const double  tolerance = 1e-7 
)

Construct a Manifold object which will project points on the TopoDS_Shape sh, along the given direction.

Member Function Documentation

◆ clone()

template<int dim, int spacedim>
std::unique_ptr< Manifold< dim, spacedim > > OpenCASCADE::DirectionalProjectionManifold< dim, spacedim >::clone ( ) const
overridevirtual

Clone the current Manifold.

Reimplemented from FlatManifold< dim, spacedim >.

Reimplemented in OpenCASCADE::DirectionalProjectionBoundary< dim, spacedim >.

◆ project_to_manifold()

template<int dim, int spacedim>
Point< spacedim > OpenCASCADE::DirectionalProjectionManifold< dim, spacedim >::project_to_manifold ( const ArrayView< const Point< spacedim >> &  surrounding_points,
const Point< spacedim > &  candidate 
) const
overridevirtual

Perform the actual projection onto the manifold. This function, in debug mode, checks that each of the surrounding_points is within tolerance from the given TopoDS_Shape. If this is not the case, an exception is thrown.

The projected point is computed using OpenCASCADE directional projection algorithms.

Reimplemented from FlatManifold< dim, spacedim >.

Member Data Documentation

◆ sh

template<int dim, int spacedim>
const TopoDS_Shape OpenCASCADE::DirectionalProjectionManifold< dim, spacedim >::sh
protected

The topological shape which is used internally to project points. You can construct such a shape by calling the OpenCASCADE::read_IGES() function, which will create a TopoDS_Shape with the geometry contained in the IGES file.

Definition at line 175 of file manifold_lib.h.

◆ direction

template<int dim, int spacedim>
const Tensor<1, spacedim> OpenCASCADE::DirectionalProjectionManifold< dim, spacedim >::direction
protected

Direction used to project new points on the shape.

Definition at line 180 of file manifold_lib.h.

◆ tolerance

template<int dim, int spacedim>
const double OpenCASCADE::DirectionalProjectionManifold< dim, spacedim >::tolerance
protected

Relative tolerance used by this class to compute distances.
