multiview rendering 45 views?

[blas_t_dozer]

I'd like to put Dolphin into one of these holographic devices:



It would mean I would have to extend Dolphin's stereo mode to more than 2 eyes--for these devices potentially up to 45 views, in a horizontal rail.

I was looking through the code at places where StereoMode is used, like:

Code:

static u32 CalculateEFBLayers()
{
 return (g_ActiveConfig.stereo_mode != StereoMode::Off) ? 2 : 1;
}

It seems, given the way the camera can already be moved with the stereo hack, that what I'm after would be possible! My questions for the devs:

1. Would performance be reasonable? With the way the geometry shader duplexes out the stereo views, can we guess about how rendering 45 views of a single GameCube frame on a beefy graphics card would do?
2. Is it possible to modify the projection matrix of the camera before rendering?
   

Any thoughts at all are welcome before I go down the road of building Dolphin, etc. Thanks!
