ComputeGraph

iOSmacOStvOSwatchOSvisionOS

ComputeGraph is a GPU-accelerated compute graph framework for building 3D spatial simulations with Metal across iOS, macOS, tvOS, and visionOS. You assemble a simulation from a ComputeNodeGraph of connected nodes, wiring them together through PortReference values and driving the result with a ComputeGraphSimulation. The framework includes viewpoint control through Viewpoint and types such as CoordinateSpace, and gives you GPU memory management through AddressSpace, while element behavior and graph computation are described with types like ElementSpawnParameters, Topology, UnaryOperation, BinaryOperation, and StandardLibraryFunction.

Essentials 3

Drive a GPU-accelerated spatial simulation by assembling and running a graph of compute nodes.

  • Cl
    ComputeGraphSimulationiOS 27.0+
    A simulation of particles, which use a single pipeline.
  • St
    ComputeNodeGraphiOS 27.0+
    A structure that represents a graph of connected compute nodes describing a spatial simulation.
  • St
    PortReferenceiOS 27.0+
    A reference to another group's values.

Viewpoint and Input 2

Control the simulation's camera viewpoint and respond to pointer input.

  • St
    Viewpoint
    Camera viewpoint parameters in 3D space.
  • St
    MouseParams
    Parameters describing mouse interaction in 3D space.

Elements and Topology 4

Describe how simulation elements are spawned, grouped, and connected into geometry.
