## Member Function Documentation

size_t VrmlData_IndexedFaceSet::ArrayColorInd | ( | const Standard_Integer **& | arrColorInd | ) | const`[inline]`

  | Query the array of color indice Parameters:
  | arrColorInd | `[out]` array of colorIndex as it is described in VRML2.0 spec
Returns: Number of integers in the array arrColorInd.

size_t VrmlData_IndexedFaceSet::ArrayNormalInd | ( | const Standard_Integer **& | arrNormalInd | ) | const`[inline]`

  | Query the array of normal indice Parameters:
  | arrNormalInd | `[out]` array of normalIndex as it is described in VRML2.0 spec
Returns: Number of integers in the array arrNormalInd.

size_t VrmlData_IndexedFaceSet::ArrayTextureCoordInd | ( | const Standard_Integer **& | arrTextureCoordInd | ) | const`[inline]`

  | Query the array of texture coordinate indice Parameters:
  | arrTextureCoordInd | `[out]` array of texCoordIndex as it is described in VRML2.0 spec
Returns: Number of integers in the array texCoordIndex.

Standard_EXPORT Quantity_Color VrmlData_IndexedFaceSet::GetColor | ( | const Standard_Integer | iFace,
|  | const Standard_Integer | iVertex
| ) |

  | Query a color for one node in the given element. The color is interpreted according to fields myColors, myArrColorInd, myColorPerVertex, as defined in VRML 2.0. Parameters:
  | iFace | rank of the polygon [0 .. N-1]
  | iVertex | rank of the vertex in the polygon [0 .. M-1]. This parameter is ignored if (myColorPerVertex == False)
Returns: Color value (RGB); if the color is indefinite then returns (0., 0., 0.)

Standard_EXPORT gp_XYZ VrmlData_IndexedFaceSet::GetNormal | ( | const Standard_Integer | iFace,
|  | const Standard_Integer | iVertex
| ) |

  | Query a normal for one node in the given element. The normal is interpreted according to fields myNormals, myArrNormalInd, myNormalPerVertex, as defined in VRML 2.0. Parameters:
  | iFace | rank of the polygon [0 .. N-1]
  | iVertex | rank of the vertex in the polygon [0 .. M-1]. This parameter is ignored if (myNormalPerVertex == False)
Returns: Normal vector; if the normal is indefinite then returns (0., 0., 0.)

VrmlData_IndexedFaceSet::Handle | ( | VrmlData_Normal |  | ) | `[private]`

VrmlData_IndexedFaceSet::Handle | ( | VrmlData_Coordinate |  | ) | `[private]`

  | If the normals are not defined, here we compute them from the polygons. Parameters:
  | theArray | Array of float values having length: if myNormalPerVertex==TRUE : 3 * myCoords->Length() if myNormalPerVertex==FALSE: 9 * number_of_triangles

virtual Standard_EXPORT VrmlData_IndexedFaceSet::Handle | ( | VrmlData_Node |  | ) | const`[virtual]`

| Create a copy of this node. If the parameter is null, a new copied node is created. Otherwise new node is not created, but rather the given one is modified. Reimplemented from VrmlData_Node.

virtual Standard_EXPORT const VrmlData_IndexedFaceSet::Handle | ( | TopoDS_TShape |  | ) | `[virtual]`

| Query the shape. This method checks the flag myIsModified; if True it should rebuild the shape presentation. Implements VrmlData_Geometry.

const VrmlData_IndexedFaceSet::Handle | ( | VrmlData_Coordinate |  | ) | const`[inline]`

| Query the Coordinates.

const VrmlData_IndexedFaceSet::Handle | ( | VrmlData_TextureCoordinate |  | ) | const`[inline]`

| Query the Texture Coordinates.

const VrmlData_IndexedFaceSet::Handle | ( | VrmlData_Color |  | ) | const`[inline]`

| Query the Colors.

const VrmlData_IndexedFaceSet::Handle | ( | VrmlData_Normal |  | ) | const`[inline]`

| Query the Normals.

Standard_Integer VrmlData_IndexedFaceSet::IndiceNormals | ( | const Standard_Integer | iFace,
|  | const Standard_Integer *& | outIndice
| ) | `[inline]`

  | Query normals indice for one face. This method should be called after checking myArrNormalInd != NULL, otherwise exception will be thrown. Parameters:
  | iFace | rank of the face [0 .. N-1]
  | outIndice | `[out]` array of normals indice
Returns: number of indice in the array - the dimension of outIndice array

virtual Standard_EXPORT Standard_Boolean VrmlData_IndexedFaceSet::IsDefault | ( |  | ) | const`[virtual]`

| Returns True if the node is default, so that it should not be written. Reimplemented from VrmlData_Node.

Standard_Integer VrmlData_IndexedFaceSet::Polygon | ( | const Standard_Integer | iFace,
|  | const Standard_Integer *& | outIndice
| ) | `[inline]`

  | Query one polygon. Parameters:
  | iFace | rank of the polygon [0 .. N-1]
  | outIndice | `[out]` array of vertex indice
Returns: number of vertice in the polygon - the dimension of outIndice array
