little Confusion

Hi...
I am new to NxOgre and Ogre as well
The question in my mind is...
1.do we need to use Physx sdk files in our project for physics??
2.What NxOgre exactly does...because we use critter to bind with Ogre

for ex if wants to implement kinematics then what we r going to use...NxOgre or Phyx.
if we use NxOgre then why Phyx in the picture...vice versa.

1. You need the PhysX SDK installed. But your project does not need to reference it if you use NxOgre. Of course once compiled you will need the PhysX dlls in your application folder.

2. NxOgre wraps PhysX but doesn't pay any favoritism to any 3D graphics engine. Critter wraps some parts of NxOgre to use with Ogre.

so it means that we don't need any phyx header files to have physics in our project...what we need is only dll, right?
but what if we want to implement part from Phyx samples

If you need specific PhysX features that NxOgre doesn't support, then you can include and use PhysX with NxOgre.

Last question....

If you need specific PhysX features that NxOgre doesn't support, then you can include and use PhysX with NxOgre.

just as normal or i need to make some changes in it...

Thanks for your support...Thank you very much
