Constructor & Destructor Documentation

◆ NURBSPatchManifold()

template<int dim, int spacedim>
OpenCASCADE::NURBSPatchManifold< dim, spacedim >::NURBSPatchManifold ( const TopoDS_Face &  face,
const double  tolerance = 1e-7 
)

The constructor takes an OpenCASCADE TopoDS_Face face and an optional tolerance. This class uses the interval OpenCASCADE variables u, v to describe the manifold.

Definition at line 440 of file manifold_lib.cc.

Member Function Documentation

◆ clone()

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

Clone the current Manifold.

Implements Manifold< dim, spacedim >.

Definition at line 450 of file manifold_lib.cc.

◆ pull_back()

template<int dim, int spacedim>
Point< 2 > OpenCASCADE::NURBSPatchManifold< dim, spacedim >::pull_back ( const Point< spacedim > &  space_point) const
overridevirtual

Pull back the given point from the Euclidean space. Will return the uv coordinates associated with the point space_point.

Implements ChartManifold< dim, spacedim, 2 >.

Definition at line 460 of file manifold_lib.cc.

◆ push_forward()

template<int dim, int spacedim>
Point< spacedim > OpenCASCADE::NURBSPatchManifold< dim, spacedim >::push_forward ( const Point< 2 > &  chart_point) const
overridevirtual

Given a chart_point in the uv coordinate system, this method returns the Euclidean coordinates associated.

Definition at line 476 of file manifold_lib.cc.

◆ push_forward_gradient()

template<int dim, int spacedim>
DerivativeForm< 1, 2, spacedim > OpenCASCADE::NURBSPatchManifold< dim, spacedim >::push_forward_gradient ( const Point< 2 > &  chart_point) const
overridevirtual

Given a point in the spacedim dimensional Euclidean space, this method returns the derivatives of the function \(F\) that maps from the uv coordinate system to the Euclidean coordinate system. In other words, it is a matrix of size \(\text{spacedim}\times\text{chartdim}\).

This function is used in the computations required by the get_tangent_vector() function.

Refer to the general documentation of this class for more information.

Definition at line 486 of file manifold_lib.cc.

◆ get_uv_bounds()

template<int dim, int spacedim>
std::tuple< double, double, double, double > OpenCASCADE::NURBSPatchManifold< dim, spacedim >::get_uv_bounds ( ) const
protected

Return a tuple representing the minimum and maximum values of u and v. Precisely, it returns (u_min, u_max, v_min, v_max)

Definition at line 517 of file manifold_lib.cc.

Member Data Documentation

◆ face

template<int dim, int spacedim>
TopoDS_Face OpenCASCADE::NURBSPatchManifold< dim, spacedim >::face
protected

An OpenCASCADE TopoDS_Face face given by the CAD.

Definition at line 414 of file manifold_lib.h.

◆ tolerance

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

Tolerance used by OpenCASCADE to identify points in each operation.
