GMModelInterfaces Interface CATVertex
Usage: an implementation of this interface is supplied and you must use it as is. You should not reimplement it.
interface CATVertex
Interface representing a topological vertex.
A vertex is a topological cell which geometry is a
point. Vertices are used to define the extremities of an edge, but they can also
be immersed in faces, volumes or 3D space.
A vertex is created with the or
methods and deleted with the
method.

- The pointer to the body in which the bounded edges are searched.
- iTopData
- The object defining the CATSoftwareConfiguration and the CATCGMJournalList.
- Returns:
- The pointer to the created iterator. You must delete this operator after use.
o EvalSharpness
| public virtual EvalSharpness( | | iEdge1, |
| | iEdge2, |
| | oContinuity, |
| | oAngle | = NULL, |
| | oOrientation | = NULL, |
| | oDefinedContinuity | = NULL, |
| | iMinSharpAngle | = CATTopSharpAngle) |
-
Returns the continuity of this CATVertex with respect to 2 bounded edges.
- Parameters:
-

- The first edge bounded by this.
- iEdge2
- The second edge bounded by this.
- oContinuity
- The evaluated continuity :
Possible values:
- CATSharp
-
- CATSmooth
-
- oAngle
- Used to ouput the angle between the two edges.
If NULL, this argument is not filled out.
- oOrientation
- Used to ouput the correct orientation of the second edge.
If NULL, this argument is not filled out.
- oDefinedContinuity
- The way the continuity has been filled out (stored or computed).
Legal values:
- TRUE
- if SetContinuity has been previously applied.
- FALSE
- geometric evaluation of continuity.
If NULL, this argument is not filled out.
- iMinSharpAngle
- Minimum angle value for which the vertex is declared Sharp
- o GetGeometryOnEdge

-
Returns the geometry of this CATVertex with respect to a given edge.
- Parameters:
-
- iBoundedEdge
- The pointer to an edge bounded by this.

- ioParamOnEdgeCurve
- The parameter on iBoundedEdge of this.
- iSide
- The start or end point of the edge. If you do not specify the CATSide,
this method raises an exception if iBoundedEdge start and end
vertices are the same.
- o GetPoint
-
| public virtual GetPoint( | ) |
-
Returns the geometry of this CATVertex.
