Detailed Description

Abstract base class for patch constructors.

Patch constructors are responsible for identifying PnS patch types and creating PatchBuilders. PatchBuilder is returned instead of a Patch directly so that updated patches can be easily if the underlying mesh changes without needing re-traverse the entire mesh to dentify the patch type and gather the vertices again. Essentially, this class indentifies PnS patch types and collects information required to build associated Bézier patches.

Member Function Documentation

getGroupName()

virtual std::string PatchConstructor::getGroupName ( ) const

pure virtual

Returns the name of the patch group this constructor handles.

This method must be implemented in derived classes to return the specific patch group name.

Returns

The name of the patch group.

Implemented in ExtraordinaryPatchConstructor, NGonPatchConstructor, PolarPatchConstructor, RegularPatchConstructor, T0PatchConstructor, T1PatchConstructor, T2PatchConstructor, and TwoTrianglesTwoQuadsPatchConstructor.

getPatchBuilder() [1/2]

virtual PatchBuilder PatchConstructor::getPatchBuilder ( const FaceHandle & , MeshType & a_Mesh, bool mark_gathered = false )

inlinevirtual

Constructs a PatchBuilder for the patch type at the given face.

Parameters

a_Mesh	The mesh to which the face belongs.
mark_gathered	If true, all vertices gathered for the patch will be marked. See Helper::mark_face_verts.

Returns

A PatchBuilder configured for the patch type at the given face.

Exceptions

std::runtime_error

if not implemented in derived class.

Reimplemented in NGonPatchConstructor, T0PatchConstructor, T1PatchConstructor, and T2PatchConstructor.

getPatchBuilder() [2/2]

virtual PatchBuilder PatchConstructor::getPatchBuilder ( const VertexHandle & , MeshType & a_Mesh, bool mark_gathered = false )

inlinevirtual

Constructs a PatchBuilder for the patch type at the given vertex.

Parameters

a_Mesh	The mesh to which the vertex belongs.
mark_gathered	If true, all vertices gathered for the patch will be marked. See Helper::mark_vert.

Returns

A PatchBuilder configured for the patch type at the given vertex.

Exceptions

std::runtime_error

if not implemented in derived class.

Reimplemented in ExtraordinaryPatchConstructor, PolarPatchConstructor, RegularPatchConstructor, and TwoTrianglesTwoQuadsPatchConstructor.

isSamePatchType() [1/2]

virtual bool PatchConstructor::isSamePatchType ( const FaceHandle & , MeshType & a_Mesh, bool check_marked = false )

inlinevirtual

Given a face, checks wither the face and the neighborhood arund the face of this patch type.

Parameters

a_Mesh	The mesh to which the face belongs.
check_marked	If true, the function will return false if any vertex of the face is marked. See Helper::is_marked.

Returns

true if the face and its neighborhood match this patch type.

Reimplemented in NGonPatchConstructor, T0PatchConstructor, T1PatchConstructor, and T2PatchConstructor.

isSamePatchType() [2/2]

virtual bool PatchConstructor::isSamePatchType ( const VertexHandle & , MeshType & a_Mesh, bool check_marked = false )

inlinevirtual

Given a vertex, checks wither the vertex and the neighborhood arund the vertex of this patch type.

Parameters

a_Mesh	The mesh to which the vertex belongs.
check_marked	If true, the function will return false if the vertex is marked. See Helper::is_marked.

Returns

true if the vertex and its neighborhood match this patch type.

Reimplemented in ExtraordinaryPatchConstructor, PolarPatchConstructor, RegularPatchConstructor, and TwoTrianglesTwoQuadsPatchConstructor.
