How do I add something to the ViewingPlatform side of my scenegraph in such a way that it stays in front of the viewplatform as it moves around?
Alright, I sorted it myself. For anyone else looking for this topic, the answer is to use the PlatformGeometry object (treat it as a branchgroup) and add things to that.
I also had problem because when I used a positive z translation I was moving it behind the viewplatform so I got no error but also could not see my object. A negative z translation solved that, though.
The Z axis goes negative into the screen so you always have negative Z numbers infront of you.
This totally screws with my head as in my game the acceleration of the ship is always in the direction of the viewplatform. Engines behind me so accel goes forward. Hence accelleration is always negative… :
