Hi!
Since long time ago I want to add a dynamic convert type to Synfig
libraries. It would allow to track one guided vector position from other
tracker vector position using a dynamic (mass-damper-spring) link.
The inclusion of bones in the latest development would make this new
convert type more interesting even.
To handle a mass-damper-spring system it is needed to solve a second order
differential equation (ODE), particularly a pair of first order ODE.
To do that the classic maths points to use the Runge-Kutta integration
methods. I can write from ground up those integration methods because it is
not so complex but I would like to use the Boost/Odeint libraries because
they allow to use adaptive steps to reduce errors in large integrations
steps.
Currently I'm doing development only on Windows platform, since it is the
computer that I have when I have a little free time.
I've seen that the linux build script uses the boost version 1.53.0 which
is exactly the one I need to include the Odeint boost libraries. But in the
windows script there is no way to specify the boost libraries to be used
(or at last I don't understand how to define it). I've only seen one code
line where it unpacks the retrieved library and it is the 1.50.0 version.
The thing is that I need help to make possible to use the 1.53.0 library
version in Windows.
Thanks!
