Detailed Description

Parameters that fully describe a collision shape.

Only the fields relevant to the chosen type need to be set.

type	relevant fields
Sphere	radius
Box	halfExtents
Capsule	radius, height (total, tip-to-tip)
Cylinder	radius, height (total)
ConvexHull	meshVertices + customScale (per-axis stretch)
Mesh	meshVertices + meshIndices + customScale
Plane	halfExtents.x / halfExtents.z (broadphase rect)

meshVertices / meshIndices are populated by the caller right before kPhysicsManager::createObject() (typically from the owning kMesh) — they aren't serialised because they're derived from the mesh asset.

customScale is applied to ConvexHull / Mesh shapes via Jolt's ScaledShape wrapper so the user can stretch a mesh-derived collider on each axis. Defaults to (1,1,1).
