Collision_Representation

Mapped https://mapped.com/schema/mapped/1.0/openusd#Collision_Representation

Geometry explicitly authoritative for physics and collision. A render mesh never becomes collision geometry without one of these.

Hierarchy

Parent classes: Representation

Subclasses: none, this is a leaf class.

Fact	Value
URI	`https://mapped.com/schema/mapped/1.0/openusd#Collision_Representation`
Source	Mapped
Protobuf	`COLLISION_REPRESENTATION`
Deprecated	No

Property	Type	Required	Default	Description
`closedVolumeRequired`	`boolean`			Whether validation requires the collision geometry to be a closed, watertight volume.
`collisionApproximation`	`string`			How a mesh is simplified for collision, mirroring UsdPhysics physics:approximation one-for-one in upper snake case: NONE, CONVEX_HULL, CONVEX_DECOMPOSITION, BOUNDING_SPHERE, BOUNDING_CUBE or MESH_SIMPLIFICATION. Meaningful only on a representation realised by hasPrimBinding; an analytic shape is not an approximation of a mesh.

exactType is always Collision_Representation.

Inherited properties (9)

Property	Type	Required	Description
`connectorIds`	`Array<string>`		The ids of the connectors associated with the entity.
`coordinateFrameId`	`string`		Opaque reference into the external coordinate frame registry, matching the Frame_Geometry decision that frames resolve outside the Mapped graph. On a Representation it is optional: absent means the subject entity's own frame.
`dateCreated`	`dateTime`		Datetime when it is created.
`dateUpdated`	`dateTime`		Datetime when it is updated last time.
`description`	`string`
`geometryHash`	`string`		Digest of the normalised geometry a representation designates, letting it version independently of its siblings.
`id`	`string`	Yes	A globally unique ID in Mapped services.
`name`	`string`
`organizationId`	`string`	Yes	The id of the organization that owns the entity.

No relationships of its own.

Inherited relationships (5)

Relationship	Targets	Inverse	Cardinality	Notes
`contributesProperty`	`Meta`	`hasPropertyContributedFrom`	0..*	transitive, canonical Mapped's internal relationship indicating that a vertex is contributing a property/value to another vertex.
`hasPrimBinding`	OpenUSD_Prim_Binding	`isPrimBindingOf`	0..*	transitive, canonical Attaches a prim address. Used directly on an entity for pure addressing that carries no physical claim, and on a Representation or level-of-detail heuristic to realise it in USD.
`hasShape`	Analytic_Shape	`isShapeOf`	0..*	transitive, canonical Realises a representation parametrically instead of through a prim. A representation is realised by exactly one of hasPrimBinding or hasShape.
`isConstraintTarget`	Spatial_Constraint	`constrainsAgainst`	0..*	The constraints evaluated against this representation or entity.
`isRepresentationOf`	Thing, Place	`hasRepresentation`	0..*	The entities whose geometry this representation designates.
