Methods

ClipFins(Boolean)

Declaration
public bool ClipFins(bool bClipLoners)
Parameters
Type Name Description
Boolean bClipLoners
Returns
Type Description
Boolean

ContractBorderByOneRingNeighbours()

remove all triangles in vertex one-rings of current selection to set. On a large mesh this is quite expensive as we don't know the boundary, so we have to iterate over all triangles.

Return false from FilterF to prevent triangles from being deselected.

Declaration
public void ContractBorderByOneRingNeighbours()

Deselect(IEnumerable<Int32>)

Declaration
public void Deselect(IEnumerable<int> triangles)
Parameters
Type Name Description
IEnumerable<Int32> triangles

Deselect(Int32)

Declaration
public void Deselect(int tid)
Parameters
Type Name Description
Int32 tid

Deselect(Int32[])

Declaration
public void Deselect(int[] triangles)
Parameters
Type Name Description
Int32[] triangles

DeselectAll()

Declaration
public void DeselectAll()

DeselectGroup(Int32)

Declaration
public void DeselectGroup(int gid)
Parameters
Type Name Description
Int32 gid

ExpandToFaceNeighbours(Func<Int32, Boolean>)

Declaration
public void ExpandToFaceNeighbours(Func<int, bool> FilterF = null)
Parameters
Type Name Description
Func<Int32, Boolean> FilterF

ExpandToFaceNeighbours(Int32, Func<Int32, Boolean>)

Declaration
public void ExpandToFaceNeighbours(int rounds, Func<int, bool> FilterF = null)
Parameters
Type Name Description
Int32 rounds
Func<Int32, Boolean> FilterF

ExpandToOneRingNeighbours(Func<Int32, Boolean>)

Add all triangles in vertex one-rings of current selection to set. On a large mesh this is quite expensive as we don't know the boundary, so we have to iterate over all triangles.

Return false from FilterF to prevent triangles from being included.

Declaration
public void ExpandToOneRingNeighbours(Func<int, bool> FilterF = null)
Parameters
Type Name Description
Func<Int32, Boolean> FilterF

ExpandToOneRingNeighbours(Int32, Func<Int32, Boolean>)

Expand selection by N vertex one-rings. This is significantly faster than calling ExpandToOnering() multiple times, because we can track the growing front and only check the new triangles.

Return false from FilterF to prevent triangles from being included.

Declaration
public void ExpandToOneRingNeighbours(int nRings, Func<int, bool> FilterF = null)
Parameters
Type Name Description
Int32 nRings
Func<Int32, Boolean> FilterF

FillEars(Boolean)

Declaration
public bool FillEars(bool bFillTinyHoles)
Parameters
Type Name Description
Boolean bFillTinyHoles
Returns
Type Description
Boolean

FindBorderTris()

find set of tris just inside border of selection

Declaration
public List<int> FindBorderTris()
Returns
Type Description
List<Int32>

FindNeighbourTris()

find set of tris just outside border of selection

Declaration
public List<int> FindNeighbourTris()
Returns
Type Description
List<Int32>

FloodFill(Int32, Func<Int32, Boolean>, Func<Int32, Boolean>)

Grow selection outwards from seed triangle, until it hits boundaries defined by triangle and edge filters. Edge filter is not effective unless it (possibly combined w/ triangle filter) defines closed loops.

Declaration
public void FloodFill(int tSeed, Func<int, bool> TriFilterF = null, Func<int, bool> EdgeFilterF = null)
Parameters
Type Name Description
Int32 tSeed
Func<Int32, Boolean> TriFilterF
Func<Int32, Boolean> EdgeFilterF

FloodFill(Int32[], Func<Int32, Boolean>, Func<Int32, Boolean>)

Grow selection outwards from seed triangles, until it hits boundaries defined by triangle and edge filters. Edge filter is not effective unless it (possibly combined w/ triangle filter) defines closed loops.

Declaration
public void FloodFill(int[] Seeds, Func<int, bool> TriFilterF = null, Func<int, bool> EdgeFilterF = null)
Parameters
Type Name Description
Int32[] Seeds
Func<Int32, Boolean> TriFilterF
Func<Int32, Boolean> EdgeFilterF
