Y axis orientation
« on: December 02, 2011, 07:25:40 am »
I was playing with HelloWorld-AE example that is included with the library and I noticed that positive Y axis goes down and negative Y axis goes up. Is there some method which can invert this?. I mean, I want positive Y axis goes up and negative Y axis goes down.

Thanks for your answer.

No, that's the way it is: http://www.jpct.net/wiki/index.php/Coordinate_system

The reason is mainly a historical with the desktop version and the software renderer and that i wanted to make positive z go into the screen. After all, it really doesn't matter...it's all just about numbers. There are many coordinate systems where z goes up and y to the right and whatever and one can work with that too.
