Detailed Description

Class to build a points field bars.

Class to build parallelepipeds based on a point field. This class generates a set of parallelepipeds where the bases are on the plane XY and the heights are given by the altitude for each point on the point field. The parallelepipeds are colored as a function of values for each point.

Colors of the bars depend on the current data mapping. If the method setDataMapping(dataMapping) is called, the current data mapping is "dataMapping". Otherwise the current data mapping is specified in the current inherited state (cf property node PoDataMapping and its derived classes). If there is no current data-mapping (i.e setDataMapping() not called and no PoDataMapping node traversed before in the scene graph), all bars get the same color which is the inherited color.

Member Function Documentation

static const SoNodekitCatalog* PoPointsFieldBars::getClassNodekitCatalog ( ) [static]

Returns the SoNodekitCatalog for this class.

Reimplemented from PoGraphMaster.

static SoType PoPointsFieldBars::getClassTypeId ( ) [static]

Returns the type identifier for this class.

Reimplemented from PoGraphMaster.

const PbDataMapping* PoPointsFieldBars::getDataMapping ( ) const

Gets a reference to a PbDataMapping object to the association color-value.

virtual const SoNodekitCatalog* PoPointsFieldBars::getNodekitCatalog ( ) const [virtual]

Returns the SoNodekitCatalog for this instance.

Reimplemented from PoGraphMaster.

virtual SoType PoPointsFieldBars::getTypeId ( ) const [virtual]

Returns the type identifier for this specific instance.

Reimplemented from PoGraphMaster.

virtual void PoPointsFieldBars::rebuild ( ) [virtual]

Forces node-kit rebuilding.

See PoBase.

Reimplemented from PoBase.

void PoPointsFieldBars::setDataMapping ( PbDataMapping * dataMapping )

Sets a reference to a PbDataMapping object to the association color-value.

If this method is not called (or called passing NULL as argument), this is the data mapping defined in the current inherited state (defined with the property node PoDataMapping and its derived classes) which is used.
