declare_vector()

VectorRef MayaFlux::Buffers::VolumeGridBuffer::declare_vector	(	std::string	name,
		Kinesis::LatticeSemantics	semantics = {}
	)

Declare a double-buffered vector field.

Parameters

name	Lookup key, unique within this volume.
semantics	What the values mean. A velocity field wants VectorVariance::ContravariantRelative; the default assumes three unrelated scalars.

Returns

Ref naming the field, or a ref with an empty name if the declaration was rejected.
