XrTransformControlOp
User interface Control Operator¶
The XrTransformControlOp maintains the state of the mixed reality user interface for the volumetric rendering application. It consumes controller events and produces user interface state structures as well as parameters for the volume rendering operator. The operator is application specific and will grow over time to include additional user interface widgets.
