InstancePoses

public static class InstancePoses

The instances this process holds whose own space is turned against their host scope's (NEB-426, docs/scope-frames.md D12): built upright in their own space and posed at a door that is not upright in the host (a door on a sphere). Learned from the instances' lease rows (InstanceContainerInfo.HasPose) when their first container is registered here, and forgotten with their last. A point p of the instance's space is origin + rotation × (p − origin) in its host's.

Properties

Count

public static int Count { get; }

How many turned instances this process holds.

Instances

public static IEnumerable<ulong> Instances { get; }

Every turned instance's id (the client's drawing pass walks them).

Methods

TryGet

public static bool TryGet(ulong instanceId, out Double3 origin, out Quaternion rotation);

The pose of instanceId, when it is turned against its host.

RotationOf

public static Quaternion RotationOf(ulong instanceId);

The instance's axes in its host's: identity for any scope that is not turned.

Turn

public static Quaternion Turn(ulong from, ulong to);

What turns a rotation (or a direction) of scope from's space into scope to's, for an entity crossing between them through a door: identity unless either is a turned instance. A game keeping its own heading or velocity bookkeeping (a pawn's yaw) applies it when its entity changes scope.

ToHost

public static Double3 ToHost(ulong instanceId, Double3 point);

A point of instanceId's own space in its host's (the identity for a scope that is not turned).

FromHost

public static Double3 FromHost(ulong instanceId, Double3 point);

A point of the host's space in instanceId's own (the inverse of ToHost).
