struct ComputeGraphViewpointComponent

A transient component that provides camera viewpoint information to the particle simulation. Attach this component to an entity to supply the simulation with an observer's position and direction. The simulation uses these values for view-dependent effects such as billboard orientation or camera-facing particles. Both properties are optional. When `nil`, the simulation falls back to its default viewpoint behavior.
