From a quick glance, this and most software doing “constraint programming” deal with discrete problems. Not saying those are useless for mechanical modeling or 3D animation, but those areas typically deal with continuous constraints which require different solvers. My experience in this is limited to a single class in CP 3 years ago so take this with a grain of salt!!

- kdmccormick 7y agoWhat about mechanical constraints that are expressed in terms of integer ratios? Could constraint programming be useful for that subset of mechanical constraints?
- tobmlt 7y agoUsing interval arithmetic and interval analysis, constraint solving can be extended to continuous problems. This seems first to have been done in the 80s by extending Prolog. As you say, most constraint software does not do this, but I vouch that it both exists and works! I wrote a relational interval constraint solver for automated CAD design. It used constraints to eliminate infeasible regions of a design space before a nonlinear solver would generate the actual geometry. It was pretty fun puzzling out how to build this thing!
