Cairn
/kɛrn/A transitional Rapier-backed physics wrapper and grounded-controller foundation; Meridian-owned Cairn solver internals remain planned.
01 / Purpose
Make physical behavior stable enough to build a world on.
A transitional Rapier-backed physics wrapper and grounded-controller foundation; Meridian-owned Cairn solver internals remain planned.
02 / Ambition
Physics that can be precise, destructive, and still understandable.
The technical guide keeps current implementation and long-term direction separate.
- 01
Responsive character movement and stable world interaction
- 02
Deterministic modes where a workload actually needs them
- 03
Structural systems and destruction as first-class physics work
- 04
Dedicated 2D and 3D paths instead of treating one as a thin disguise for the other
03 / Direction
Move from a useful wrapper toward Cairn-owned behavior.
- Cairn-native body, shape, query, and solver contracts
- Provenance-controlled fork and differential testing
- Structural destruction as a flagship workload
- Dedicated first-class 2D physics path
