public mrpt::viz::CVisualObject (Class CVisualObject)

Class Documentation

class CText3D : public mrpt::viz::CVisualObject 

A 3D text (rendered with OpenGL primitives), with selectable font face and drawing style. Use setString and setFont to change the text displayed by this object (can be multi-lined).

Text is drawn along the (+X,+Y) axes.

Default size of characters is “1.0 units”. Change it with the standard method CVisualObject::setScale() as with any other 3D object. The color can be also changed with standard methods in the base class CRenderizable.

Must be implemented by derived classes to provide the updated bounding box in the object local frame of coordinates. This will be called only once after each time the derived class reports to notifyChange() that the object geometry changed.
