operator()() [3/4]

auto MayaFlux::Evolve::operator() ( const std::shared_ptr< Buffers::VolumeGridBuffer > &  volume, const Buffers::VolumeGridBuffer::FlowConfig &  flow, const RenderConfig &  render  ) -> std::shared_ptr<Buffers::VolumeGridBuffer>

inline

Set the incompressible flow stages going over a volume and attach rendering.

Parameters

volume	Unregistered volume. Built with a SurfaceConfig if it is to be drawn.
flow	Flow parameters. Required refs left with an empty name (velocity, pressure, divergence, and scratch when viscosity is above zero) are declared on the volume under default names. A named ref the volume does not yet hold is declared, with the slot count its role needs. A ref issued by another volume is left for setup_flow to reject.
render	Render target. target_window is required.

Returns

The volume, or nullptr if it is null or the target window is null.

Registers the volume in the graphics domain, which establishes its chain, then builds the flow stages and attaches rendering. The stages setup_flow builds are reachable afterwards through the volume's processing chain by type.
