Split Screen

How would I go about implementing split screen functionality? It seems that 2 cameras are needed, but from all indications it does not seem possible to render from 2 ICameraSceneNodes, and then take their images and combine them together for the final output. Any suggestions?

Check example 18 in the examples folder - it shows how to implement splitscreens.

It's quite easy. I was surprised about how easy it is when I integrated it into my current project "Stunt Marble Racers". Here is some pseudo-code on how it works:

Code: Select all

smgr->beginScene();
driver->setViewport(viewPortOfPlayer1);
smgr->setActiveCamera(cameraOfPlayer1);
smgr->drawAll();
driver->setViewport(viewPortOfPlayer2);
smgr->setActiveCamera(cameraOfPlayer2);
smgr->drawAll();
smgr->endScene();

I hope I remembered that correctly, I don't have the code here at work. But you could check out my game (and it's sources), the splitscreen rendering is (IIRC) done in CGame::update.
