Each set of Instances and/or frames used as input to the Volumetric Presentation State specified by one Item in Volumetric Presentation State Input Set Sequence (0070,120A) is identified by Volumetric Presentation Input Set UID (0070,1209). The Volumetric Presentation State Input Sequence (0070,1201) references Items in Volumetric Presentation Input Set Sequence (0070,120A) by their UID and specifies the particular processing to be performed prior to compositing with other inputs to build the final presentation view.

Volumetric Presentation Input Set UID (0070,1209) may be shared among multiple Volumetric Presentation State Instances using the same input data.
