Detailed Description

The IfcIndexedColourMap provides the assignment of colour information to individual faces.

Details - It is used for colouring faces of tessellated face sets. The IfcIndexedColourMap defines an index into an indexed list of colour information. The Colours are a two-dimensional list of colours provided by three RGB values. The ColourIndex attribute corresponds to the CoordIndex of the IfcTessellatedFaceSet defining the corresponding index list of faces. The Opacity attribute provides the alpha channel for all faces of the tessellated face set. The next image shows an indexed colour map.

Indexed colour map geometry:

On this image IfcTriangulatedFaceSet is represented by: IfcTriangulatedFaceSet.CoordIndex: ((1,6,5),(1,2,6), (6,2,7), (7,2,3), (7,8,6), (6,8,5), (5,8,1), (1,8,4), (4,2,1), (2,4,3), (4,8,7), (7,3,4)) IfcCartesianPointList.CoordList: ((0.,0.,0.), (1.,0.,0.), (1.,1.,0.), (0.,1.,0.), (0.,0.,2.), (1.,0.,2.), (1.,1.,2.), (0.,1.,2.)) IfcIndexedColourMap.ColourIndex: (1, 1, 2, 2, 3, 3, 1, 1, 1, 1, 1, 1, ) IfcColourRgbList.ColourList: ((1.,0.,0.), (0.,1.,0.), (1.,1.,0.))

Default constructor for the IfcIndexedColourMap class.

Member Function Documentation

◆ colourIndex()

OdDAI::ListOfInt & OdIfc4x2::IfcIndexedColourMap::colourIndex ( )

Returns the value of ColourIndex attribute. This attribute is an index into the IfcColourRgbList for each face of the IfcTriangulatedFaceSet. The colour is applied uniformly to the indexed face.

Returns: Returns the value of ColourIndex attribute.

◆ getAttr() [1/2]

virtual OdRxValue OdIfc4x2::IfcIndexedColourMap::getAttr ( const char * attrName ) const

overridevirtual

Returns an attribute value for the specified attribute name.

Parameters

attrName [in] Name of an attribute to query.

Returns: OdRxValue object that represents a generic variant type value.

◆ getAttr() [2/2]

virtual OdRxValue OdIfc4x2::IfcIndexedColourMap::getAttr ( const OdIfc::OdIfcAttribute attrDef ) const

overridevirtual

Returns an attribute value for the specified attribute definition.

Parameters

attrDef [in] Attribute definition to query.

Returns: OdRxValue object that represents a generic variant type value.

Reimplemented from OdIfc::OdIfcInstance.

◆ getColourIndex()

void OdIfc4x2::IfcIndexedColourMap::getColourIndex ( OdArray< int > & ColourIndex ) const

Returns the value of ColourIndex attribute. This attribute is an index into the IfcColourRgbList for each face of the IfcTriangulatedFaceSet. The colour is applied uniformly to the indexed face.

Parameters

ColourIndex [out] Receives an array of colour indexes.

◆ getColours()

const OdDAIObjectId & OdIfc4x2::IfcIndexedColourMap::getColours ( ) const

Returns the value of Colours attribute. Colours is indexable list of lists of quadruples, representing RGB colours.

Returns: Returns the value of Colours attribute.

◆ getInstanceType()

virtual OdDAI::Entity * OdIfc4x2::IfcIndexedColourMap::getInstanceType ( ) const

overridevirtual

Returns a type of a class instance.

Returns: Pointer to the <exref target=https://docs.opendesign.com/tkernel_api_cpp/OdDAI__Entity.html>>OdDAI::Entity</exref> type that determines an entity definition within a schema.

Reimplemented from OdIfc4x2::IfcPresentationItem.

◆ getMappedTo()

const OdDAIObjectId & OdIfc4x2::IfcIndexedColourMap::getMappedTo ( ) const

Returns the value of MappedTo attribute. This attribute is reference to the IfcTessellatedFaceSet to which it applies the colours and alpha channel.

Returns: Returns the value of MappedTo attribute.

◆ getOpacity()

double OdIfc4x2::IfcIndexedColourMap::getOpacity ( ) const

Returns the value of Opacity attribute. Opacity is the the opacity value, that applies equally to all faces of the tessellated face set. 1.0 means opaque, and 0.0 completely transparent. If not provided, 1.0 is assumed (all colours are opaque).

Returns: Returns the value of Opacity attribute.

Remarks: The definition of the alpha channel component for opacity follows the new definitions in image processing, where 0.0 means full transparency and 1.0 (or 2bit depths -1) means fully opaque. This is contrary to the definition of transparency in IfcSurfaceStyleShading.

◆ inFields()

virtual OdResult OdIfc4x2::IfcIndexedColourMap::inFields ( OdDAI::OdSpfFilerBase * rdFiler )

overridevirtual

Reads object's data from the specified filer.

Parameters

rdFiler [in] Pointer to a filer from which to read the data.

Returns: A value of OdResult type that contains the result of the method execution.

◆ isKindOf()

overridevirtual

Checks whether the specified instance is the object derived from or belongs to this class.

Parameters

entityType [in] Entity to check.

Returns: true if the specified instance is the object derived from or belongs to this class, false otherwise.

Reimplemented from OdIfc4x2::IfcPresentationItem.

◆ outFields()

Parameters

Opacity [in] Opacity to set.

Remarks: The definition of the alpha channel component for opacity follows the new definitions in image processing, where 0.0 means full transparency and 1.0 (or 2bit depths -1) means fully opaque. This is contrary to the definition of transparency in IfcSurfaceStyleShading.
