About

shapes started out as my second Haskell project. I'm still working on it.

Libraries

shapes-math: TemplateHaskell-generated vector math using GHC primops (in place of linear)
shapes: physics engine implementation
shapes-demo: interactive demo and debugging tool for shapes

Engine Components

Contact: find contacts between shapes - e.g. Separating Axis Test (SAT)
Constraint: general form (and solution) for constraints on motion of objects
Solver: solving the set of all constraints in a world
Broadphase: finding potential interactions (that would give rise to constraints)

How the Solver works

start at Physics.Engine.Main

Broadphase: Compare axis-aligned bounding boxes (Aabb) to find pairs of objects that may be interacting. Feed these pairs into the solver.
Generate constraint generators.

* Calculate contacts between a pair of objects (`SAT`).
* Create generators for relevant constraints at each contact (e.g. `Friction`, `NonPenetration`)
* Constraint generators are evaluated with the objects' current state (see 4, Note).

For each constraint generator that also existed in the previous frame, apply the previous frame's constraint solution.
Evaluate and solve each constraint generator in sequence. (Optional: repeat this step)

Note: Solving a constraint affects the velocity of the object(s).
