Detailed Description

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

A Boundary object based on OpenCASCADE TopoDS_Shape where where new points are first computed by averaging the surrounding points in the same way as FlatManifold does, and are then projected in the normal direction 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.

This could happen, for example, if you are trying to use a shape of type TopoDS_Edge when projecting on a face. In this case, the vertices of the face would be collapsed to the edge, and your surrounding points would not be lying on the given shape, raising an exception.

◆ NormalProjectionBoundary()

template<int dim, int spacedim>

OpenCASCADE::NormalProjectionBoundary< dim, spacedim >::NormalProjectionBoundary	(	const TopoDS_Shape &	sh,
		const double	tolerance = `1e-7`
	)

The standard constructor takes a generic TopoDS_Shape sh, and a tolerance used to compute distances internally.

The TopoDS_Shape can be arbitrary, i.e., a collection of shapes, faces, edges or a single face or edge.

virtual

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 normal projection algorithms.

Reimplemented from FlatManifold< dim, spacedim >.

◆ sh

template<int dim, int spacedim>

const TopoDS_Shape OpenCASCADE::NormalProjectionBoundary< dim, spacedim >::sh

private

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 101 of file boundary_lib.h.

◆ tolerance

template<int dim, int spacedim>

const double OpenCASCADE::NormalProjectionBoundary< dim, spacedim >::tolerance

private

Relative tolerance used by this class to compute distances.
