You ‘ve credibly heard a thing or two about Nintendo ‘s brand-new hand-held games console, the Nintendo 3DS. It ‘s the follow-up to the vastly popular DSi, and as Ninty is wasting no time in telling you, it lets you play games in eye-snapping 3D without having to wear any dorky glasses. It ‘s an advanced feature, but is it actually any good ? Read on for our verdict on the 3DS ‘ 3D technical school, and impress your friends by knowing how the blast thing actually works .
Wait, glasses-free 3D? What is this black magic?
Viewing a 3D double on a screen without using any glasses might sound complicate, but in fact the engineering used in the 3DS is deceptively simpleton. As your eyes perceive the worldly concern from slenderly different angles, with the two images melded in your mind to provide the sense of depth, to make 3D appear on a single panel, you have to make the filmdom appearance two images at once — one for each eye. The 3DS has a thin layer in front of its display called a ‘parallax barrier ‘, and this thin sheet is entire of actually bantam gaps. These gaps mean certain parts of the blind are hidden from one angle, but visible from another. so with your two eyes placed at different angles to the screen, each voyeur sees a slenderly different painting.
All the 3DS has to do is slice up two identical like images and place them behind the barrier, arranged so your leave eye can view certain parts of the image, and the right eye can see others. With a different picture hitting each eye, your brain does its combination voodoo, and a sense of depth is achieved .
This diagram, adapted from one on Flickroom, shows how the 3DS’ screen is able to deliver separate images to each of your eyes.
So does it look good?
absolutely. The 3DS is n’t the only implementation of this technical school we ‘ve seen to date, but it ‘s the best use of it therefore far. We ‘ve played respective of the 3DS ‘ launching titles, and while some games make better manipulation of the consequence than others, the smell of astuteness, the fluidity of the 3D and a commemorate miss of indistinctness means you can relax and let the effect dip in while you play games. It ‘s rarely distract, and it can make for an enjoyable, immersive gambling experience. More impressive than the 3D alone is the fact you can adjust the effect, or turn it off wholly whenever you want. A slider to the right of the exceed screen adjusts the horizontal surface of the 3D — slide it downwards and the effect lessens, flattening by degrees until the persona is wholly flat. The bearing of this skidder makes us think the 3D effect will — in all games — be an optional ocular enhancement, preferably than a gameplay necessity. If you do n’t want it, you can turn it off at your leisure. In 2D things look great excessively, with the screen vibrant and sharp .
Too good to be true?
It ‘s true the 3D effect is truly impressive, but there are situations where you ‘ll want to turn it off. here ‘s why. As we mentioned before, your eyes need to be lined up with the riddle in such a way that each eye sees unlike parts of the expose through the parallax barrier. That ‘s quite a accurate angle — you ‘ll need to be viewing the display from precisely head-on. If you move your promontory out of this dessert spotlight, the spell is broken and the persona will appear bleary.
practically speaking, you wo n’t be able to get two people side by side enjoying the 3D effect at once, and even experiencing it by peeking over person ‘s shoulder is more or less impossible ( something competently demonstrated by disappoint passerby in our agency ). A bumpy escape or judder Tube travel will besides prove a bite besides much, and there are besides respective games, such as Super Money Ball, that require you to move the 3DS around to control the in-game action. At times like these, you ‘d be better off switching to 2D mode. We ‘re not besides refer though — as we said, the 3D impression looks great, and if you fancy going without it for a while, it ‘s easy to switch off. ideally we ‘d rather the effect had a wide-eyed viewing angle, so we never felt the motivation to switch it off, but as this is n’t the case, we appreciate having a academic degree of manipulate over the multi-dimensional action.

We suggest getting your hand on a 3DS to check the effect out for yourself. It ‘s impressive, and we ‘re excited to see what developers can do with the technology. The 3DS is n’t all flashy stuff flying virtually into your font — there ‘s a metric ton of other bang-up features rammed inside its bantam chassis to keep you occupied.
