Interface SpaceGraphEdge

Portal (door, opening, or generic transition) between two adjacent SpaceGraphNodes. Carries the world-space mid-point of the portal plus the through-direction so the tour planner can build cross-portal camera trajectories that thread the door rather than clip into the surrounding wall.

For IFC sources, dataObjectId typically references an IfcDoor or IfcOpeningElement. For the geometry fallback extractor, edges are synthesised from wall-aperture detection and dataObjectId is omitted.

interface SpaceGraphEdge {
    dataObjectId?: string;
    from: string;
    height?: number;
    id: string;
    normal: Vec3;
    position: Vec3;
    sceneObjectId?: string;
    to: string;
    width?: number;
}

Properties

OptionaldataObjectId

dataObjectId?: string

DataObject id, e.g. an IfcDoor global id.

from

from: string

SpaceGraphNode.id of one of the two adjacent spaces.

Optionalheight

height?: number

Portal height in world units, if known.

id

id: string

Unique edge id within the parent SpaceGraph.

normal

normal: Vec3

Unit normal pointing from from toward to. Used by samplers to bias viewpoint look-direction toward the exit door, and by the tour planner to orient mid-portal flight tangents.

position

position: Vec3

World-space mid-point of the portal opening.

OptionalsceneObjectId

sceneObjectId?: string

SceneObject id backing the portal (e.g. the door's SceneObject).

to

to: string

SpaceGraphNode.id of the other adjacent space.

Optionalwidth

width?: number

Portal width in world units, if known.
