Re: Unreal Engine 4 post-processing

Postprocessing usually has a well-known and uniform, fixed rendering code on the order of a couple miliseconds. The big benefit to doing stuff like AA and other algorithms (reflections, etc) in screen space is that their cost becomes fixed, i.e. it's one less variable to worry about that could tank ...

Re: Laser projectors general? [zero lag & zero blur!!!]

Speaking of laser projectors, projection dream has a review of an expensive laser-illuminated one:

Re: Laser projectors general? [zero lag & zero blur!!!]

Terrific links, very informative. The factors contributing to contrast ratio involved in the second link pertain more to commercial cinema than home theater, since at least in home theater you can increase the room contrast quite easily and cheaply by using black velvet material: http://projectiondr...

Re: Laser projectors general? [zero lag & zero blur!!!]

Typical primaries used in most gamuts don't follow the entire range of possible colours. I meant the example of a mega-number of primaries in Pointer's Gamut as an example of how to achieve a similar measured spectrum as to what the eye perceives, and since lasers have narrow bandwidth you could inc...

Re: Laser projectors general? [zero lag & zero blur!!!]

Front projection with a pair of devices at better than 60Hz with laser frequencies designed to minimize problems with metamerism would be top on my list. Don't care at all about resolution. Don't care if it is only 8-bit per channel per device, temporal dither both devices differently should solve ...

Re: Laser projectors general? [zero lag & zero blur!!!]

Light123, if your screen tech is solid, then PATENT IT IMMEDIATELY. Do NOT share your designs on the internet before you do that. THEN you can turn around and sell this screen to IMAX + other laser cinemas (which is a market that's bound to take off, including the home market eventually). And of cou...

Re: Laser projectors general? [zero lag & zero blur!!!]

I read that Toronto was one of the cities in which Star Wars 7 was shown in HDR. But not at Imax, I believe, it was at a Dolby Cinema I think. Maybe I'm wrong. I do love Imax though, but unless it's being shown on 70mm film then DCI 2K/4K doesn't contain HDR by default AFAIK. Or maybe it just starte...

Re: Cascaded Displays: Spatiotemporal Superresolution

Isn't this the same thing as interlaced resolutions on CRTs? Not really, both images are in full res stacked one on top of the other. The main difference is they are offsetting the image of one of them with some kind of smart dither pattern in order to achieve better anti-aliasing. It seems like th...

Re: Laser projectors general? [zero lag & zero blur!!!]

imo it's still a buzzword in the same way "HD" was a buzzword a few years ago. personally, it's nothing too exciting. e.g. hd was just adding more pixels, hdr is just adding more max luminance and bitdepth to go along with it. and when i'm indoors, i don't really care to see exceptionally bright hi...
