TopologicalOperators Class CATSkinExtrapol

Usage: you must use this class as is. You should never derive it.


public class CATSkinExtrapol

Class representing an operator that extrapolates a shell body.

The edges to extrapolate must be on the boundary of the shell, or must lie on a bounding edge of a shell.
The extrapolation values can be different for each edge. A positive value defines an extrapolation along the outside direction of the shell.
Current limitation: the operator runs on bodies that only contain one shell, made of only one face. Moreover, the extrapolation gives a result that is continuous in curvature. To use it:

Method Index


o Append(CATEdge*,CATLength)
Appends an edge to extrapolate.
o Append(CATLISTP(CATEdge),CATLength)
o Append(CATLISTP(CATEdge)&,CATLength)
Appends a list of edges to extrapolate.
o GetJournal()

o GetResult()
Returns the pointer to the resulting body.
o Run()
Runs this operator.
o SetDefaultExtrapolationValue(CATLength)

o SetFreezeMode(CATBodyFreezeMode)
Sets the ability to later modify the resulting body.
o SetPropagationMode(int)
Defines the propagation mode of the extrapolation value.

Constructor and Destructor


o ~CATSkinExtrapol
public ~CATSkinExtrapol()

Methods


o Append
public Append( iBoundaryEdge,
iExtrapolValue)
Appends an edge to extrapolate. It replaces the current value of an already selected edges by iExtrapolValue.
Parameters:
iBoundaryEdge
The edge to append.
iExtrapolValue
The extrapolation value for the iBoundaryEdge edge.
o Append
public Append( iBoundaryEdges,
iExtrapolValue)
o Append
public Append( const iBoundaryEdges,
iExtrapolValue)
Appends a list of edges to extrapolate. It replaces the current value of an already selected edges by iExtrapolValue.
Parameters:
iBoundaryEdges
The list of edges to append.
iExtrapolValue
The common extrapolation value for all the edges of the iBoundaryEdges list.
o GetJournal
public GetJournal()
Returns a pointer to the topological journal dedicated to this CATSkinExtrapol operator.
Only available if a journal was given at the creation of the operator.
o GetResult
public GetResult()
Returns the pointer to the resulting body.
o Run
public Run()
Runs this operator.
o SetDefaultExtrapolationValue
public SetDefaultExtrapolationValue( iExtrapolValue)
Selects all the edges of the shell boundary and sets to them a common extrapolation value.
Parameters:
iExtrapolValue
The new current extrapolation value of the already selected edges.
o SetFreezeMode
public SetFreezeMode( iFreezeMode)
Sets the ability to later modify the resulting body.
Parameters:
iFreezeMode
The freeze mode.
o SetPropagationMode
public SetPropagationMode( iPropagationMode)
Defines the propagation mode of the extrapolation value.
Parameters:
iPropagationMode
0
No propagation of the extrapolation value.
1
Defines the automatic definition of the extrapolation value on an edge to the one of its tangential adjacent edges. This mode is used by default at the creation of the operator.
