Detailed Description

Class for a valued markers field.

Class to build a valued markers field in the plane XY. A valued markers field is a list of markers which can be colored and can have different sizes. By default all markers have the same size and the same color.

Colors of the markers 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 markers get the same color which is the inherited color.

FILE FORMAT/DEFAULT

PoValuedMarkerField {

point	0 0
value	0
size	0
markerString	"."

}

CATALOG PARTS

PoValuedPointField {
Separator alternateRep (from PoBase) {

AppearanceKit appearance (from PoBase)
Specifies the appearance of all the kit. By default lightModel.model=BASE_COLOR. If markerString !=".", the font used for markers is the font set in font.name.
MatrixTransform domainTransform (from PoBase)
Corresponds to the domain transformation.
Group valuedPointField
Contains a list of SoText2 (markerString !=".") or SoPointSet (markerString = ".") shapes to draw markers.
}
}

Member Function Documentation

static const SoNodekitCatalog* PoValuedMarkerField::getClassNodekitCatalog

(

)

[static]

Returns the SoNodekitCatalog for this class.

Reimplemented from PoGraphMaster.

static SoType PoValuedMarkerField::getClassTypeId

(

)

[static]

Returns the type identifier for this class.

Reimplemented from PoGraphMaster.

const PbDataMapping* PoValuedMarkerField::getDataMapping

(

)

const

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

virtual const SoNodekitCatalog* PoValuedMarkerField::getNodekitCatalog

(

)

const [virtual]

Returns the SoNodekitCatalog for this instance.

Reimplemented from PoGraphMaster.

virtual SoType PoValuedMarkerField::getTypeId

(

)

const [virtual]

Returns the type identifier for this specific instance.

Reimplemented from PoGraphMaster.

virtual void PoValuedMarkerField::rebuild

(

)

[virtual]

Forces node-kit rebuilding.

See PoBase.

Reimplemented from PoBase.

void PoValuedMarkerField::setDataMapping

(

PbDataMapping *

dataMapping

)

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

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.

Member Data Documentation

SoSFString PoValuedMarkerField::markerString

The markers are defined by a string.

If this field is equal to ".", the markers are SoPointSet shapes, otherwise SoText2 shapes. To change the font of text markers, set the catalog part appearance.font.name . Be careful, for the moment, text markers are not vertically aligned.

SoMFVec2f PoValuedMarkerField::point

List of coordinates for the markers.

SoMFFloat PoValuedMarkerField::size

List of sizes used to calculate the marker sizes.

If the number of sizes is equal to number of points of point , marker have a size depending on size, otherwise all the markers have the same size.

SoMFFloat PoValuedMarkerField::value

List of values used to color the markers.

If the number of values is equal to number of points of point , marker have a color depending on the current data mapping (see description of PoValuedMarkerField), otherwise all the markers have the same color.
