worldToScreen??

[malte]

Hi,
I do have a couple of questions regarding the worldToScreen and the worldtoscreen functions.

1. What exactly is the difference between these two? I assume they are essentially doing the same thing?

2. More importantly, I need to know the exact screen coordinates of objects in the world. worldtoscreen seems to work fine, at least until the object is not on the screen anymore but somewhere to the side or even behind the virtual camera. What exactly does the worldtoscreen function in these situations?

Thanks for any feedback,
