Ogre 3D 1.7

Time for action — adding wireframe and point render mode

We use the code we just created, and as always, simply add the code we need for this new feature:

1. We need a new member variable in the framelistener to save the current render mode:

   Ogre::PolygonMode _PolyMode;
   

2. Init the value in the constructor with PM_SOLID:

   _PolyMode = Ogre::PolygonMode::PM_SOLID;
   

3. We then add a new if condition in the frameStarted() function, which tests if the R key is pressed. If this is the case, we can change the render mode. If the current mode is solid, and we want it to be wireframe:

   if(_key->isKeyDown(OIS::KC_R))
   {
   if(_PolyMode == PM_SOLID)
   {
   _PolyMode = Ogre::PolygonMode::PM_WIREFRAME;
   }
   

4. If it is wireframe, and we want it to change to point mode:

   else if(_PolyMode ...
