Text orientation in space or towards observer

MuPAD® notebooks are not recommended. Use MATLAB® live scripts instead.

MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.

With Billboarding = TRUE, text objects are always facing the observer. With Billboarding = FALSE, text objects retain their orientation relative to other objects.

Often, text objects in 3D are used to label certain places in a graphic (note that objects can contain a title, so text objects are usually only necessary for additional descriptions). In this case, it is desirable that they always face the observer to be readable and not rotate along with the rest of the scene. This is the default behavior. To get text objects that are actually part of the scene in the sense that rotating the scene also rotates the texts, set Billboarding = FALSE.


Example 1

In the following image, the prime numbers use Billboarding = TRUE, while other numbers do not:

                 [3*i, 0, 0],
                 TextOrientation = [1, 0, 0, 0, 1, 0],
                 Billboarding = isprime(i))
     $ i = 1..15, 
     TextFont = [20], Scaling = Constrained, Axes = None)

Note that text objects with Billboarding = TRUE ignore TextOrientation.
