struct ComputeGraphRuntimeComponent

Manages the live GPU simulation for an entity's ``ComputeGraphComponent_v1``. RealityKit creates the ComputeGraphRuntimeComponent automatically on the first frame that a ComputeGraphComponent becomes active. You do not need to add it manually.

readOutput

TypeScript

readOutput(port: _ComputeGraph_ComputeNodeGraph_Port_Address): (SDKHandle) | null

Swift declaration

func readOutput(_ port: ComputeNodeGraph.Port.Address) -> (any MTLBuffer)?

Returns the output buffer for the port at the given address. - Parameter port: The port address of the output to read. - Returns: The `MTLBuffer` for that port, or `nil` if not found.

readOutputs

TypeScript

readOutputs(node: number): (Array<SDKHandle>) | null

Swift declaration

func readOutputs(_ node: ComputeNodeGraph.NodeID) -> [any MTLBuffer]?

Returns all output buffers for the given output node. - Parameter node: The node identifier whose output buffers should be read. - Returns: An array of `MTLBuffer` objects, or `nil` if the node identifier is invalid or no output buffers are found.
