bind() [6/9]

void MayaFlux::Nodes::Network::GpuFieldOperator::bind	(	FieldTarget	target,
		const Kinesis::ParametricVectorField &	field,
		std::optional< uint32_t >	cluster = std::nullopt
	)

Bind a three-component field of position, time and live parameters.

Parameters

target	Mask over POSITION, COLOR, NORMAL and TANGENT.
field	Parametric field with a usable shader half.
cluster	See the DualVectorField overload's own doc.

Validation matches the DualField overload. The emitted function takes the time push constant and the vec4 set with set_params(), so changing the parameters never rebuilds the spec.
