A Verse-authored creative device that can be placed in a level

sw_scene_graph_utils — conversion helpers between Verse.org SpatialMath (LUF) and

UnrealEngine.com/Temporary/SpatialMath (XYZ) types.



Entity/SceneGraph APIs (GetGlobalTransform / SetGlobalTransform) use Verse.org

SpatialMath.  All arithmetic (ring offsets, TeleportTo, FortChar.GetTransform)

uses UnrealEngine SpatialMath.  These extension methods bridge between the two.



Usage example:

Center := LobbyEntity.GetGlobalTransform().FromLUF().Translation  # xyz_vec3

luf_vec3  := (/Verse.org/SpatialMath:)vector3xyz_vec3  := (/UnrealEngine.com/Temporary/SpatialMath:)vector3

luf_rot   := (/Verse.org/SpatialMath:)rotationxyz_rot   := (/UnrealEngine.com/Temporary/SpatialMath:)rotation

luf_xform := (/Verse.org/SpatialMath:)transformxyz_xform := (/UnrealEngine.com/Temporary/SpatialMath:)transform

── vector3 conversions ───────────────────────────────────────────────────────

(Pos : xyz_vec3).ToLUF() : luf_vec3 =FromVector3 of Pos

(Pos : luf_vec3).FromLUF() : xyz_vec3 =FromVector3 of Pos

── rotation conversions ──────────────────────────────────────────────────────

(Rot : xyz_rot).ToLUF() : luf_rot =FromRotation of Rot

(Rot : luf_rot).FromLUF() : xyz_rot =FromRotation of Rot

── transform conversions ─────────────────────────────────────────────────────

(Xform : xyz_xform).ToLUF() : luf_xform =FromTransform of Xform

(Xform : luf_xform).FromLUF() : xyz_xform =FromTransform of Xform

── Convenience: get an entity’s world position as an xyz_vec3 (UnrealEngine)

so callers don’t need to import both SpatialMath modules. ───────────────────

GetEntityWorldXYZ(E : entity) : xyz_vec3 =E.GetGlobalTransform().FromLUF().Translation
