Using a different coord system
Posted: Fri Dec 30, 2005 4:35 pm
Hello
I spent a few years working with the Unreal Tournament engine and as such its coordinate system has become very dear to me. It uses a RH system with the in-game camera having X being forward, Y being left and Z being up (see first pic). This is different to the default system Irrlicht uses, which is a LH system with X being forward, Z being left and Y being up (see second pic). I'd like to know if it's possible to set up my scene using the UT coord system.
This is how Irrlicht is at the moment:
...and this is how I want it to be:
I've looked at the ICameraSceneNode interface and see there's no way to set the View transform, so I'm guessing I'll need to create a custom ICameraSceneNode implementation and set the View transform so it rearranges the coords as I want. Or is there an easier way that I've overlooked?
Thanks
Joel
