I am asking this question to save some time and I am expecting answers only from people who have tried something like this before. (I realize that I could just try it and see if it works, but that takes a non-trivial amount of time.)
Suppose you wrote a simulation in pure Mathematica. As the simulation progresses, a vector is being periodically updated changed. One could then have a
Dynamic@ListPlot[vector] and watch the progress "live".
Now the question is: is this possible when using LibraryLink? With LibraryLink it's possible to access a kernel variable (
vector) directly. Is it possible to get the system to register the changes to that variable and to run the
Dynamic when necessary? Or is there an alternative simple (low effort) way to achieve the same, i.e. use Mathematica to visualize a simulation "live"?
One way I see that certainly work is periodically calling back to the kernel through a MathLink connection and setting a variable through Mma code, which contains the information to be visualized. Is there a simpler/better way?
