PicoGK
PicoGK is a compact and robust geometry kernel
...The library uses a deliberately reduced but powerful instruction set for building computational geometry. It supports geometry generation through voxel fields, lattices, implicit shapes, meshes, and robust Boolean operations. It can be used as the foundation for advanced engineered parts such as heat exchangers, electric motors, bio-inspired structures, and rocket engine components. Overall, PicoGK is meant for developers and engineers who want programmable, repeatable, and highly expressive geometry creation for real-world manufacturing. -

Logic Calculator
A Calculator to perform logical operations
The Logic Calculator is an application useful to perform logical operations. It has three modes: (1) Evaluation of logic formulae: In this mode we have the basic boolean operations (negation, conjunction, disjunction, conditional and biconditional) so the user can insert the logic formula and the Logic Calculator displays the truth table along with the models of the formula. (2) Logical entailment: In this mode the user can insert a number of premises followed by a number of conclusions, so the Logic Calculator displays the truth table of each premise / conclusion and the result of whether or not these premises logically entail the given conclusions... -
