Split Screen For Multiple Scenes

[OverlordOutpost]

I'm being asked for a project to make Irrlicht split *all* scenes played through it.

I know how to split an individual scene thanks for the tutorial, and can import that code into most any scene for an easy split for that scene only, but the person is asking me for a way to have every scene (including ones already built) split-screen, either through a .dll change or some sort of preloading.

Is there a step in the right direction on how this can be done, or can it even be done like that?

Do you mean having multiple scenes displayed at once? You need a seperate scene manager for every scene you want to display which can be created by "ISceneManager::createNewSceneManager". I'm using this method to preview the selected level in "Stunt Marble Racers". You have a scene in the background and the selected level being previewed in another small viewport.

Is this how you can do some GUI thing with a gun? I mean have a camera looking at a gun in an FPS style, and then have that scene on a 'layer' in front of the main 3d scene? Like an overlay scene(<---OMG BLENDER!!!) ?

I don't know. Have never tried that. What I did was this:



You can see a scene with a rotating cube with my logo in the background and in the upper right corner you see a preview of the selected track.

For the fps gun thing you should just render it manually after the scene and before the gui to be sure its on top of everything. no need to render to a different texture

Oh doh!, of course! I keep forgetting about the emergent flexibility of irrlicht and c++. Thanks!

I guess I should've been a bit more specific. The person I'm working with has a Head-Mounted Device, with two monitors inside it, one for left eye and one for right eye. It's read the screen like a horizontal split

Left Eye
-----------
Right Eye

Like so. I can code the split screen individually for each scene that the guy wants to run in the HMD, but I won't always be there, and he doesn't like to touch C++. So what I'm wondering is if there's something I can add, a preloader program, or a change to the irrlicht.dll that'll apply that horizontal split automatically to any loaded scene.

Hmm, what kind of software is preloaded into the headset? I'm sure it might be something like putting each view-port onto dual monitors on a desk.

Oh .. in that case you only need one scene manager but two viewports. Check for code that uses mutliple viewports and use that code instead of the normal "beginScene --> drawall --> endScene". You just need to set the viewports right.
