3D box class.
Definition SbBox.h:81
3D vector class.
Definition SbLinear.h:120
Abstract base class for all actions.

Justification
Justification types.
Definition SoText2.h:130
virtual ~SoText2()
virtual void computeBBox(SoAction *action, SbBox3f &box, SbVec3f &center)
Computes bounding box of text.
SoMFString string
The text string(s) to display.
Definition SoText2.h:141
virtual void rayPick(SoRayPickAction *action)
Implements picking along a ray by intersecting the ray with each primitive generated by subclass.
SoText2()
Creates a 2D text node with default settings.
SoSFFloat spacing
Defines the distance (in the negative y direction) between the base points of successive strings,...
Definition SoText2.h:147
virtual void generatePrimitives(SoAction *action)
This method is a no-op for SoText2, since there are no primitives it can generate.
virtual void GLRender(SoGLRenderAction *action)
Implements rendering by rendering each primitive generated by subclass.
SoSFEnum justification
Indicates placement and alignment of strings.
