declare_vector()

VectorRef MayaFlux::Buffers::VolumeGridBuffer::declare_vector

(

std::string

name

)

Declare a double-buffered vector field.

Parameters

name	Lookup key, unique within this volume.

Returns

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

Vector fields are always double-buffered. The single-slot case saves one slot, a megabyte at 64 cubed, and every vector field in use is either advected or diffused, both of which require two.
