I could see here in BRL-CAD wiki that lipc/lipg are the libraries to manage geometric constraints:
However, this is presented as a work in progress, while this library is already present in BRL-CAD package.
I would like to know what is the status of the geometric constraint solver of BRL-CAD please?
I thank you in advance for your feedbacks.
Have a good day!
Hopefully Dawn can reply with more specific/detailed status information. He the developer ( http://brlcad.org/wiki/User:Homovulgaris ) that worked on libpc for a while and wrote up the description you referred to.
The libpc library is present in BRL-CAD but it's not finished. There is more work needed to hook in throughout the system for implicit and explicit constraint expressions. Are you interested in continuing that development effort? Or are you a user needing that feature?
No to both questions :).
Actually, I am leading a short survey to knwo which open source CAD software use which open source geometric solver?
I end up with the following results at the moment:
FreeCAD => freegcs
BRL-CAD => libpg / libpc
NaroCAD / HeeksCAD => sketchsolve
I also see that other open source geometric solvers exist:
After this quick surveyr, my question would have been: which one is the most "advanced / fastest / robust"?
For this, I guess a bench is needed :).
Have a good day and thanks again!
Ah, thanks for the clarification, Pierre. Well clearly, ours is the most advanced / fastest / robust! ;)
Dawn would definitely be the guy to speak up on how libpc compares feature-wise to other solvers. (The libpg candidate name was dropped in favor of libpc.)
