Can do.
> I want to create subtitles in an animation. Is this possible?
Yes. I do it all the time.

First, you have to calculate the up, right, direction and translation
vectors for the camera.
Declare the text, position it relative to the camera, and then apply
a matrix transform so that the text is moved to where the camera is.
All but a couple of my IRTC entries use subtitles in some fashion.
The source files for two of them are available on line:

I'm told this page can also be of help:
