Detailed Description

MeshViz Class to build a label field.

Builds a 2D label field on 1D mesh (PoIrregularMesh1D or PoRegularMesh1D). The abscissas of the labels are given by the geometry of the current mesh 1D, and the ordinates are given by one of the value-set of the current mesh 1D specified by the field yValuesIndex. Names attached to each label are given by one of the string-set of the current mesh 1D specified by the field stringsIndex.

The fields position, threshold and offset allows the user to set the label position and the field valueType set the values to display as labels. This class also takes into account of the current mesh 1D hints (PoMesh1DHints), and the current mesh 1D filter (PoMesh1DFilter) to filter the geometry of the current mesh 1D. The current label hints (PoLabelHints) is used to specify the appearance of labels. If the offset is different from null and, if the field isLabelLineVisible of the current label hints is set to TRUE then, a line representing the offset is drawn. All labels depend on the current miscellaneous text attributes which defines the font names, line length and so on (PoMiscTextAttr). All numerical values depend on the current numerical display format (PoNumericDisplayFormat).

The interpretation of colorBinding is the following :

  • INHERITED: All labels are colored with the same inherited color.
  • PER_PART, PER_VERTEX: A color is used for each label.

FILE FORMAT/DEFAULT

    colorBinding INHERITED

    AppearanceKit appearance (from PoBase)

    Specifies the appearance of all the kit. By default lightModel.model=PHONG.

    MatrixTransform domainTransform (from PoBase)

    Corresponds to the domain transformation.

    Group label

    Contains a list of couple SoMaterial and SoText3/SoAnnoText3/SoAsciiText (cf PoBase::setTextType() and PoBase::setVRML2Mode() for choosing the text type) if the field colorBinding is different from INHERITED, a list of SoText3/SoAnnoText3/SoAsciiText otherwise.

    Separator labelLineSep {

    Contains properties and shapes to draw the label lines.

      AppearanceKit labelLineApp

      Specifies the appearance of the label lines.

      Group labelLine

      Contains a SoLineSet shape to draw the label lines.

    }

◆ Position

Position of the labels.

Enumerator
VALUE_POS 

The label position is the given by the current mesh geometry.

MIDDLE_POS 

The abscissas (resp ordinate) is given by the current mesh 1D geometry and the ordinate (resp.

abscissas) is at the middle between the mesh ordinate (reps. abscissas) and the threshold field.

THRESHOLD_POS 

The abscissas (resp ordinate) is given by the current mesh 1D geometry and the ordinate (resp.

VALUE 

The values displayed correspond to the the ordinates (resp.

abscissas) of the current mesh 1D geometry.

Member Data Documentation

◆ axis

SoSFEnum PoLabel::axis

Defines from which axis the position and type of displayed values computation is done.

All values in brackets correspond to the Y-axis.

Definition at line 176 of file PoLabel.h.

◆ fontSize

SoSFFloat PoLabel::fontSize

Font size of labels.

If this value is less or equal to 0, the font size is fixed at 0.04. This value is a percentage of the current domain (cf PoBase description).

Definition at line 225 of file PoLabel.h.

◆ offset

SoMFVec3f PoLabel::offset

Defines an offset applied to the label.

This offset is combinated with the label position. If the number of offsets is inferior to the number of labels, they are cyclically used.

Definition at line 217 of file PoLabel.h.

◆ position

SoSFEnum PoLabel::position

Defines the position of the labels.

There are three ways to define this position :

  • VALUE_POS: The label position is the given by the current mesh geometry.
  • MIDDLE_POS: The abscissas (resp. ordinate) is given by the current mesh geometry and the ordinate (resp. abscissas) is at the middle between the mesh ordinate (reps. abscissas) and a threshold.
  • THRESHOLD_POS: The abscissas (resp. ordinate) is given by the current mesh geometry and the ordinate (resp. abscissas) is the threshold field.

Definition at line 205 of file PoLabel.h.

◆ stringsIndex

SoSFInt32 PoLabel::stringsIndex

Defines the index of the set of strings used for the names attached to labels when valueType is equal to NAME.

If the field value is negative, no names is attached to labels.

Definition at line 169 of file PoLabel.h.

◆ threshold

SoSFFloat PoLabel::threshold

Defines the threshold used to the set position of the label.

Definition at line 210 of file PoLabel.h.

◆ valueType

SoSFBitMask PoLabel::valueType

Defines the type of values displayed by the labels.

There are two ways to display the labels :

  • VALUE: The values displayed correspond to the the ordinates (resp. abscissas) of the current mesh 1D geometry.
  • NAME: The values displayed correspond to the names associated to the strings-set specified by the field stringsIndex.
