Ray Implementation ? Default Copy Constructor

Yavin · Post by **Yavin** » Mon May 09, 2005 7:43 pm

Hello Ogre::Team,

while working on some new JavaBindings I'm a little bit confused about the implementation of the Ogre::Ray class. Is it aim that the copy constructor isn't private or overloaded? I want to get a Ray object from Camera, but I need the object on the heap in order that it is alive when the scope goes back to Java. To make this work I will try the following:

Code: Select all

Ogre::Ray * pRay = new Ogre::Ray( pCam->getCameraToViewportRay( screenx, screeny ) );

Maybe someone can please tell me if this would be a good idea or not! IMHO that's not very nice.

Regards, Yavin

You are aware of Ogre4J ? (The Ogre java bindings in ogreaddons)

pCam->getCameraToViewportRay returns an Ogre::Ray object, so it is very legal to use the copy constructor. (otherwise this return value wouldn't even work)
