7 months ago We should research the literature of inferring 3-D imagery from a 2-D camera. Certainly, something getting slightly larger would imply that it’s getting closer, and something getting slightly smaller would imply that it’s getting further away. Somebody must have done this.

So far, all of the motion tracking methods under near-term consideration are based on a single-camera 2D, setup.
The team has discussed the idea of 3D motion tracking and analysis several times, and the idea keeps coming up.
There is a lot to be gained by tracking and analyzing plant motion in 3D with at least two cameras. See, for example, the paper by Stolarz, et al. titled Circumnutation Tracker: novel software for investigation of circumnutation https://plantmethods.biomedcentral.com/articles/10.1186/1746-4811-10-24. (Note that this paper describes the analysis of circumnutation, not the automated tracking thereof.)
This Issue then is a mere very high-level placeholder to applying 3D tracking and analysis to various types of motion and various tracking methods -- it's a wish and a reminder more than a specification. It's a call for ideation and further research and experimentation prior to determining which 3D features to add to Plant-Tracer/webapp, if any.
