Detailed Description

VSG extension Annotation text node.

SoAnnoText3 has some features of SoText3 and also some of SoText2.

For example, in the RENDER2D_PRINT_RASTER mode the text is rendered using SoText2, but the font size (see SoFont) is interpreted in the current 3D units like SoText3. As a result, the text is always screen aligned, but the size changes depending on distance from the camera. Text in this mode cannot be rotated.

The current annotation property (SoAnnoText3Property) determines the mode. The default is RENDER3D_PRINT_VECTOR (render like SoText3).

If scaling is applied (e.g. SoTransform) and the mode is RENDER2D_PRINT_RASTER, then the scale factor actually applied to the text is the minimum scale factor of the three axes (x, y, z).

Limitations:

  • If a stroke font is used (see SoFont), the text is rendered with lines rather than faces. Line attributes apply instead of polygon attributes. Text is not extruded.
  • When using one of the xxx_PRINT_RASTER options (see SoAnnoText3Property), the export limitations of SoText2 apply. See that class for more information.

Shape Antialiasing type is SoShape::TEXT.

FILE FORMAT/DEFAULT

    AnnoText3 {
    string ""
    spacing 1.0
    justification LEFT
    alternateRep NULL
    }

ACTION BEHAVIOR

    SoGLRenderAction
    Draws text based on the current font, profiles, transformation, drawing style, material, texture, complexity, and so on.

    SoRayPickAction
    Performs a pick on the text. The string index and character position are available from the SoTextDetail.

    SoGetBoundingBoxAction
    Computes the bounding box that encloses the text.

    SoCallbackAction
    For non-stroke fonts,if any triangle callbacks are registered with the action, they will be invoked for each successive triangle used to approximate the text geometry.

    For stroke fonts, if any line segment callbacks are registered with the action, they will be invoked for each successive line segment used to approximate the text geometry.

◆ Justification

Justification types.

Enumerator
LEFT 

Left justification.

CENTER 

Center justification.

RIGHT 

Right justification.

INHERITED 

The text justification is inherited from the current SoTextProperty::alignmentH value.

Constructor & Destructor Documentation

◆ SoAnnoText3()

SoAnnoText3::SoAnnoText3 ( )

Constructor.

Member Function Documentation

◆ getClassTypeId()

static SoType SoAnnoText3::getClassTypeId ( )
static

Returns the type identifier for this class.


◆ getTypeId()

virtual SoType SoAnnoText3::getTypeId ( ) const
virtual

Returns the type identifier for this specific instance.

Reimplemented from SoShape.

Member Data Documentation

◆ alternateRep

SoSFNode SoAnnoText3::alternateRep

This field optionally holds an SoText3 node that will be written out in place of this SoAnnoText3 node when saved to a .iv file.

Definition at line 164 of file SoAnnoText3.h.

◆ justification

SoSFEnum SoAnnoText3::justification

Indicates placement and alignment of strings.

With LEFT justification, the left edge of the first line is at the (transformed) origin, and all left edges are aligned. RIGHT justification is similar. CENTER justification places the center of the first string at the (transformed) origin, with the centers of all remaining strings aligned under it.
Use enum Justification. Default is Left.

Definition at line 158 of file SoAnnoText3.h.

◆ spacing

SoSFFloat SoAnnoText3::spacing

Defines the distance (in the negative y direction) between the base points of successive strings, measured with respect to the current font height.

A value of 1 indicates single spacing, a value of 2 indicates double spacing, and so on. Default is 1.

Definition at line 148 of file SoAnnoText3.h.

◆ string

SoMFString SoAnnoText3::string

The text string(s) to display.

Each string will appear on its own line.

Definition at line 140 of file SoAnnoText3.h.
