Detailed Description

MeshViz Rendering node that displays a legend.

Displays a legend representing the current colormap. A colormap is specified using the MoColorMapping derived nodes. However, the legend does not take into account the MoCombineColorMapping node.

The legend is drawn in a rectangle defined by the bottomLeft and topRight 2D points given in Normalized Device Coordinates [0..1].

Member Data Documentation

◆ bottomLeft

SoSFVec2f MoLegend::bottomLeft

Bottom left corner of the rectangle in which the legend will be drawn.

In NDC units [0..1]. Default is (0,0).

Definition at line 106 of file MoLegend.h.

◆ displayValues

SoSFBool MoLegend::displayValues

If TRUE, display numValues values starting from the minimal to the maximal values of the colormap.

Default FALSE.

Definition at line 170 of file MoLegend.h.

◆ maxValue

SoSFDouble MoLegend::maxValue

The maximum value defining the range of data to display in the legend.

Default 0.

Note
If not set, the min and max values are retrieved from the colormap.

Definition at line 126 of file MoLegend.h.

◆ minValue

SoSFDouble MoLegend::minValue

The minimum value defining the range of data to display in the legend.

Default 0.

Note
If not set, the min and max values are retrieved from the colormap.

Definition at line 119 of file MoLegend.h.

◆ numValues

SoSFInt32 MoLegend::numValues

The number of values displayed near the colorbar.

This field is ignored if displayValues is FALSE. Default 2.

Definition at line 178 of file MoLegend.h.

◆ title

SoSFString MoLegend::title

The title of the legend.

Definition at line 137 of file MoLegend.h.

◆ titleColor

SoSFColor MoLegend::titleColor

Color for the title of the legend.

Definition at line 147 of file MoLegend.h.

◆ titleFontSize

SoSFFloat MoLegend::titleFontSize

The size of the font for the title of the legend.

Default 10 pixels.

Definition at line 142 of file MoLegend.h.

◆ titlePosition

SoSFEnum MoLegend::titlePosition

The position of the title relative to the legend box.

Use enum Position. Default is POS_BOTTOM.

Definition at line 163 of file MoLegend.h.

◆ topRight

SoSFVec2f MoLegend::topRight

Top-right corner of the rectangle in which the legend will be drawn.

In NDC units [0..1]. Default is (0,1).

Definition at line 112 of file MoLegend.h.

◆ valueNotation

SoSFEnum MoLegend::valueNotation

Defines the notation type (fixed or scientific) used to display the values of this legend.

Use enum Notation. Default is NOTATION_DEFAULT.

Note: The field valuePrecision is interpreted according to valueNotation.

NOTE: field available since Open Inventor 9.6

Definition at line 208 of file MoLegend.h.

◆ valuePrecision

SoSFUInt32 MoLegend::valuePrecision

Defines the maximum number of significant digits to display, or the maximum number of digits after the decimal point depending on the value of the field valueNotation.

Default value is 0.

When using NOTATION_DEFAULT the valuePrecision field specifies the maximum number of meaningful digits to display in total counting both those before and those after the decimal point. Notice that it is not a minimum, and therefore it does not pad the displayed number with trailing zeros if the number can be displayed with less digits than the precision.

When using NOTATION_FIXED or NOTATION_SCIENTIFIC, the precision field specifies exactly how many digits to display after the decimal point, even if this includes trailing decimal zeros. The digits before the decimal point are not relevant for the precision in this case.

NOTE: field available since Open Inventor 9.6

Definition at line 229 of file MoLegend.h.

◆ valuesColor

SoSFColor MoLegend::valuesColor

Color for the values of the legend.

Definition at line 183 of file MoLegend.h.

◆ valuesFontSize

SoSFFloat MoLegend::valuesFontSize

The size of the font for the values of the legend.

Default 10 pixels.

Definition at line 188 of file MoLegend.h.

◆ vertical

SoSFBool MoLegend::vertical

If TRUE, the legend is vertical.

Otherwise it is horizontal. Default FALSE (horizontal)
