template<PositionCarrying T>

AABB3D MayaFlux::Kinesis::aabb ( std::span< T >  pts )

noexcept

Axis-aligned bounding box of a PositionCarrying span.

Returns AABB3D{zero, zero} for an empty span. No allocation; single linear pass.

Template Parameters

T	Any type satisfying PositionCarrying.

Parameters

pts	Non-owning span of points.

Returns

Tightest AABB enclosing all positions in pts.
