XrTransformRenderOp

User interface Render Operator

The XrTransformRenderOp renders the mixed reality user interface of the volumetric rendering application. It consumes interface widget state structures as well as render buffers into which to overlay the interface widgets. The operator is application specific and will grow over time to include additional user interface widgets.
