This tutorials are based on the irrlicht tutorial, show how to use splitscreen. You have to read the previous tutorials, because the tutorials will skips the knowledgement that we have already talked about before.
We’ll create a viewport divided into 4 parts, with 3 fixed cameras and one user-controlled.
//cameras
ICameraSceneNode *camera[4]={0,0,0,0};
// Create 3 fixed and one user-controlled cameras
//Front
camera[0] = smgr->addCameraSceneNode(0, vector3df(50,0,0), vector3df(0,0,0));
//Top
camera[1] = smgr->addCameraSceneNode(0, vector3df(0,50,0), vector3df(0,0,0));
//Left
camera[2] = smgr->addCameraSceneNode(0, vector3df(0,0,50), vector3df(0,0,0));
//User-controlled
camera[3] = smgr->addCameraSceneNodeFPS();
// don't start at sydney's position
if (camera[3])
camera[3]->setPosition(core::vector3df(-50,0,-50));
In order to split windows, we just need to set to the different camera and view point
while(device->run())
{
//Set the viewpoint to the whole screen and begin scene
driver->setViewPort(rect<s32>(0,0,ResX,ResY));
driver->beginScene(true,true,SColor(255,100,100,100));
if (SplitScreen)
{
//Activate camera1
smgr->setActiveCamera(camera[0]);
//Set viewpoint to the first quarter (left top)
driver->setViewPort(rect<s32>(0,0,ResX/2,ResY/2));
//Draw scene
smgr->drawAll();
//Activate camera2
smgr->setActiveCamera(camera[1]);
//Set viewpoint to the second quarter (right top)
driver->setViewPort(rect<s32>(ResX/2,0,ResX,ResY/2));
//Draw scene
smgr->drawAll();
//Activate camera3
smgr->setActiveCamera(camera[2]);
//Set viewpoint to the third quarter (left bottom)
driver->setViewPort(rect<s32>(0,ResY/2,ResX/2,ResY));
//Draw scene
smgr->drawAll();
//Set viewport the last quarter (right bottom)
driver->setViewPort(rect<s32>(ResX/2,ResY/2,ResX,ResY));
}
//Activate camera4
smgr->setActiveCamera(camera[3]);
//Draw scene
smgr->drawAll();
driver->endScene();
}
device->drop();
