scene = viz.MainScene
If the parent is viz.WORLD or viz.SCREEN, then the argument represents the scene to add the object to.
If the parent is viz.ORTHO, then the argument represents the window to add the object to.
If the parent is a valid node3d object, then the argument is ignored.
This command creates a flat texture-based node for displaying text in the scene.
When adding text objects to viz.ORTHO, use the
<node3d:text3d>.fontSize command to adjust the size. Text objects are aligned to the bottom left corner by default.
