Home Theater Circular Screen Example (2.35:1 Aspect Ratio)

This is an example of using NTHUSIM and a 180 degree circular screen as a home theater. In this case a movie preview is projected on the triple-projector circular screen in proper 2.35:1 aspect ratio. While it doesn't use the whole 180 degree screen while viewing movie content, this type of setup works well as both a gaming room and a home theater room. Standard Blu-ray content projected in a home theater setup like this uses about 2/3rds of the circular screen to achieve 2.35:1 aspect ratio. You can also use VLC and watch live TV in the same manner by piping the signal in through a firewire connection from a standard Motorola HD cable set top box.

would 3d look proper on this seeing as it was designed to be on a flat screen?

@counterbond 3D works just fine for me even on 180 degree gaming.

Nice! Curved screens usually require some software to reshape the picture from a Blu-ray or DVD, in order to give it a "smilebox" shape. Without it, the picture will look distorted on a curved screen.

Do you use a soft of such kind?

[BHawthorne72]

@oalternativo Yes, read the video description.

to wat degrees is the curvature? cinerama makes it to 146deg.....i wish i cud get it to 160deg and make my vision filled wid cinema XD

@kresh43 This video is quite old. I've since gone through 5 or so total revisions of the screen. No idea what FOV it used back then as that screen is no longer in assembled form. My current screen is a popup frame. Also since this video was done I now use bicubic pre-warping and edge blending (which wasn't in this video).

Wow (chills down spine). This is definitely the way to watch movies. Cinerama features would look properly displayed on this. Congratulations on this magnificent achievement!

That screen is bigger than my livingroom!

[railerswim]

You need to depress the impression lines on that curve

@sams64sf The problem with Epsons are the lens throw. You need a projector with a lens throw of 0.49:1 to 0.7:1 to achieve that large of a projection. Short throws are typically in the $500-800 price range and are 1280x800 @ 120 hz 720p 3D capable. Check out BenQ, Optoma and Viewsonic for short throws that allow that big of a projection in a short distance.
