I just started using openScenegraph and it has been pretty smooth for me till now. I am making a simple racquet-ball game for my VR class (using a CAVE system). I have some basic questions to ask..
1. What coordinate system does OSG follow ?
Right handed, I presume ? Also, x points to East ? Y up or into the screen ? I couldn't find the thumb diagram on the website. Can you guys please refer me to the right convention or link ?
2. How do I generate Bounding box/ bounding sphere for a given box/ sphere geometry? Can this information be embedded in the model and extracted using any of the plugins ?
3. Is there something pre-defined for collision detection-resolution wrt Bounding box and bounding sphere in osg ?
I am exploring ways to handle the collision between the wall and the ball and not sure if there are things already built-in open scenegraph that I can use or do I have to write code to handle that ?
I'd appreciate any help.
