Member Function Documentation

FaceToElement()

DllExport void FaceToElement	(	Mesh &	mesh,
		AdjFaceList *	af,
		BitArray &	faceSel,
		BitArray &	elementSel
	)

Remarks

Converts a face selection to an element selection.

NOTE: This method can only produce accurate results with culling if we are

certain that the face selection corresponds to the results of the last call to

the owner Mesh's SubObjectHitTest method. (To turn off culling, use GetCull ().ClearAll(). Culling is not relevant if the MESH_SELCONV_REQUIRE_ALL flag

is turned off.)

Parameters:

Mesh & mesh

The mesh that owns this interface

AdjFaceList *af

A pointer to an accurate AdjFaceList based on this mesh. (This is used to

construct elements.)

BitArray & faceSel

The face selection representing actual hits in the viewport.

BitArray & elementSel

This is where the output Element selection is stored.

FaceToPolygon()

DllExport void FaceToPolygon	(	Mesh &	mesh,
		AdjFaceList *	af,
		BitArray &	faceSel,
		BitArray &	polygonSel,
		float	faceThresh,
		bool	ignoreVisEdge = false
	)

Remarks

Converts a face selection to a polygon selection.

NOTE: This method can only produce accurate results with culling if we are

certain that the face selection corresponds to the results of the last call to

the owner Mesh's SubObjectHitTest method. (To turn off culling, use GetCull ().ClearAll(). Culling is not relevant if the MESH_SELCONV_REQUIRE_ALL flag

is turned off.)

Parameters:

Mesh & mesh

The mesh that owns this interface

AdjFaceList *af

A pointer to an accurate AdjFaceList based on this mesh. (This is used to

construct elements.)

BitArray & faceSel

The face selection representing actual hits in the viewport.

BitArray & polygonSel

This is where the output polygon selection is stored

float faceThresh

The angle threshold between faces, in radians, that would mark them as

belonging to separate polygons.

bool ignoreVisEdge=false

If true, this tells the system to ignore visible edges in constructing

polygons, and instead rely entirely on the face threshold to distinguish them.

VertexToEdge()

DllExport void VertexToEdge	(	Mesh &	mesh,
		BitArray &	vertexSel,
		BitArray &	edgeSel
	)

Remarks

Converts a vertex selection to a "By Vertex" edge selection.

NOTE: This method can only produce accurate results with culling if we are

certain that the vertex selection corresponds to the results of the last call

to the owner Mesh's SubObjectHitTest method. (To turn off culling, use GetCull ().ClearAll(). Culling is not relevant if the MESH_SELCONV_REQUIRE_ALL flag

is turned off.)

Parameters:

Mesh & mesh

The mesh that owns this interface

BitArray & vertexSel

The face selection representing actual hits in the viewport

BitArray & edgeSel

The face selection representing actual hits in the viewport

VertexToFace()

DllExport void VertexToFace	(	Mesh &	mesh,
		BitArray &	vertexSel,
		BitArray &	faceSel
	)

VertexToPolygon()

DllExport void VertexToPolygon	(	Mesh &	mesh,
		AdjFaceList *	af,
		BitArray &	vertexSel,
		BitArray &	polygonSel,
		float	faceThresh,
		bool	ignoreVisEdge = false
	)

Remarks

Converts a vertex selection to a "By Vertex" polygon selection.

NOTE: This method can only produce accurate results with culling if we are

certain that the vertex selection corresponds to the results of the last call

to the owner Mesh's SubObjectHitTest method. (To turn off culling, use GetCull ().ClearAll(). Culling is not relevant if the MESH_SELCONV_REQUIRE_ALL flag

is turned off.)

(Note that we can't just combine VertexToFace and FaceToPolygon to obtain the

results of this method, because we won't have accurate Face culling info.)

Parameters:

Mesh & mesh

The mesh that owns this interface

AdjFaceList *af

A pointer to an accurate AdjFaceList based on this mesh. (This is used to

construct elements.)

BitArray &vertexSel

The vertex selection representing actual hits in the viewport.

BitArray & polygonSel

This is where the output polygon selection is stored

float faceThresh

The angle threshold between faces, in radians, that would mark them as

belonging to separate polygons.

bool ignoreVisEdge=false

If true, this tells the system to ignore visible edges in constructing

polygons, and instead rely entirely on the face threshold to distinguish them.

VertexToElement()

DllExport void VertexToElement	(	Mesh &	mesh,
		AdjFaceList *	af,
		BitArray &	vertexSel,
		BitArray &	elementSel
	)

Remarks

Converts a vertex selection to a "By Vertex" element selection.

NOTE: This method can only produce accurate results with culling if we are

certain that the vertex selection corresponds to the results of the last call

to the owner Mesh's SubObjectHitTest method. (To turn off culling, use GetCull ().ClearAll(). Culling is not relevant if the MESH_SELCONV_REQUIRE_ALL flag

is turned off.)

(Note that we can't just combine VertexToFace and FaceToElement to obtain the

results of this method, because we won't have accurate Face culling info.)

Parameters:

Mesh & mesh

The mesh that owns this interface

AdjFaceList *af

A pointer to an accurate AdjFaceList based on this mesh. (This is used to

construct elements.)

BitArray &vertexSel

The vertex selection representing actual hits in the viewport.

BitArray &elementSel

This is where the output element selection is stored

GetCull()

BitArray& GetCull ( )

inline

Remarks

Accesses the BitArray describing which subobject components were culled in

last Mesh hit-testing. In its usual usage, this data will only be set by

Mesh::SubObjectHitTest, and will only be used by the other methods of

MeshSelectionConverter. This information does not affect selection conversion

if the MESH_SELCONV_REQUIRE_ALL flag is not set.

{ return mCull; }

SetFlag()

void SetFlag ( DWORD  f, bool  value = true  )

inline

{ if (value) mFlags |= f; else mFlags &= ~f; }

ClearFlag()

void ClearFlag ( DWORD  f )

inline

{ mFlags &= ~f; }

GetFlag()

bool GetFlag ( DWORD  f )

inline

{ return (mFlags&f) ? true : false; }

GetID()

Interface_ID GetID ( )

inlinevirtual

Remarks

This method returns the unique interface ID.

Reimplemented from BaseInterface.

Remarks

This method can be used as a direct interface delete request.

Default Implementation:

GetInterface()

DllExport BaseInterface* GetInterface ( Interface_ID  id )

virtual

Remarks

Returns a pointer to the interface whose ID is specified.
