Segment Class Reference

---

Detailed Description

A Segment is a generic concept used to describe a PolygonMesh's Edge.

Having a generic term for this concept allows the user to write code to traverse an object's geometry in a generic fashion without resorting to special case handling based on a specific geometry type.

Example:

        using namespace XSI;
        Application app;
        Model root = app.GetActiveSceneRoot();

        X3DObject myCube;
        root.AddGeometry( L"Cube", L"MeshSurface", L"", myCube );

        CSegmentRefArray segments(
            myCube.GetActivePrimitive().GetGeometry().GetSegments() );

        LONG lCount = segments.GetCount();
        for ( LONG i=0; i<lCount; i++ )
        {
            Segment segment(segments[i]);

            app.LogMessage( L"Segment.Index " +
                CValue(segment.GetIndex()).GetAsText() );
        }

Member Function Documentation

bool IsA

(

siClassID

in_ClassID

)

const [virtual]

Returns true if a given class type is compatible with this API class.

Parameters:

in_ClassID

class type.

Returns:

true if the class is compatible, false otherwise.

Reimplemented from SIObject.

Reimplemented in Edge.

siClassID GetClassID

(

)

const [virtual]

Returns the type of the API class.

Returns:

The class type.

Reimplemented from SIObject.

Reimplemented in Edge.

Segment& operator=

(

const Segment &

in_obj

)

Creates an object from another object. The newly created object is set to empty if the input object is not compatible.

Parameters:

in_obj

constant class object.

Returns:

The new Segment object.

Segment& operator=

(

const CRef &

in_ref

)

Creates an object from a reference object. The newly created object is set to empty if the input reference object is not compatible.

Parameters:

in_ref

constant class object.

Returns:

The new Segment object.

Reimplemented from SIObject.

Reimplemented in Edge.

CPointRefArray GetPoints

(

)

const

Returns an array of Point objects on this Segment object.

Returns:

Array of Point objects.

LONG GetIndex

(

)

const

Returns the index of this Segment object in the geometry's segment array.

Returns:

The Segment index.

CSampleRefArray GetSamples

(

)

const

Returns an array of Sample object on this Segment object.

Returns:

Array of Sample objects.

SubComponent GetSubComponent

(

)

const

Creates a SubComponent object from this Segment object,

Returns:

A SubComponent object

Segment Navigate

(

siNavigateComponentType

in_siNavigate

)

const

Navigates the Segment objects of the underlying geometry as specifed by the navigation component type. Navigation is circular -- for instance, navigating beyond the last component will return the first and vice versa.

Parameters:

in_siNavigate

Type of direction for navigating the Segment objects.

Returns:

The Segment object being visited.
