Hi Zak, I have been able to add geometry relative to the view by simply adding a new TransformGroup with geometry to the view platform transform. This, however, renders the geemetry in whatever perspective the view is using. SO, i know it is possible to add geometry to the scene, relative to the view, without using the PlatformGeometry.
BUT.. i think you are right.. by using PlatformGeometry, the geometry is always rendered in parallel projection. ON the other hand... is there any way to make that particular geometry always render in perspective projection???
