VHTK::VectorRoutedField Class Reference
[Volumetric Data Nodes]
Detailed Description
This is an analythical vector field with means for defining the contents through routing.Implement your vector field as a function field. Then route the position field of this node as input to that field and route the result to the value field of this node. As request for values are comming to the value extractor function of this node, the routing will be activated to define that value.
