Hello. I'm using an HMD and intersense tracker. Code-wise, I use methods like "link.postTrans", etc. to apply virtual world transformations when using the HMD directly. However, I want to use the environment for testing as well, so I'm trying to find an easy way to apply world transformations without the tracker. It's surprisingly not as easy as I thought it would be. How could I, for example, rotate the entire world 180 degrees so that the camera is situated in the same position and now facing the other way, but the virtual subject it represents hasn't physically turned around?
