Hi Haochuan, you need to derive a new class from the colvar::cvc, whose
structure is described here.
http://colvars.github.io/doxygen/html/classcolvar_1_1cvc.html#details
The rest of the webpage shows you also the current inheritance structure
(what classes are derived from what).
Among the variables that have vector values, a good example to take a look
at could be distance_pairs. Presumably you only need to wrap your C++ code
in the correct functions, and add the calls that read coordinates or send
forces.
See also:
http://colvars.github.io/doxygen/html/index.html
for documentation on the other classes.
