Lær alt om, hvad der er 3D eller tredimensionelt

Vil du vide, hvad 3D er? 3D eller tredimensionelle film og billeder bliver mere populære. Da vi er i nutiden, er det nemt at lave en 3D-film ved hjælp af forskellige værktøjer. Men først skal vi forstå alt om 3D: baggrunden, definitionen og hvordan man laver en 3D-video.

In this article, we will dig into 3D and its parameters. So, if you want to learn about what is 3D, read this article.

Del 1. Hvad er 3D

3D eller tredimensionelle objekter viser bredden, højden og dybden. Dagligt ser vi 3D-objekter, fordi vores fysiske miljø i sig selv er tredimensionelt. På grund af den 3D-perception, som vi mennesker har, kan vi opfatte 3D-objekterne, også kaldet dybdeperception. Når du ser dig omkring, danner nethinden i vores øjne et todimensionelt billede, og vores hjerne behandler de to billeder som 3D-visuals. Men vidste du det? Har vi mennesker værktøjer, som vi bruger til dybdeopfattelse?

Her er de menneskelige værktøjer, vi bruger til dybdeopfattelse:

Stereoscopic vision - Stereoscopic vision is a sense of depth perceived by the two eyes. It is one of the abilities of the brain to register 3D shapes and visuals. In this vision, the objects look separated when closer than distant ones.

Parallax - The angles between two lines measure this type of vision. When you move your head side by side, closer objects move more than distant objects.

Size Familiarity - If you are familiar with the size of an object, even though it is far, you can approximately know how big it is to appear in size. In the same way, if two objects have the same size but the other one is bigger, it is assumed that the larger one is closer.

Accommodation - When you focus on a close object, your eye’s lenses physically change. In that way, you will know how far the object is. Also, it is the way of the eye to keep the focus on an object.

Aerial Perspective - In aerial perspective, you will see objects smaller because the view is far. Distant objects also appear to have less contrast and color saturation.

Der er også forskellige slags 3D i vores fysiske verden. 3D beskrives også som et billede, der giver en illusion af dybde i forskellige afstande, hvilket er almindeligt brugt i computerspil, grafik, virtual reality og film.

Forskellige typer 3D:

3D Computer Graphics - 3D computer graphics can generate 3D objects in a display screen or two-dimensional space. The pixels in 2D graphics have different properties, such as position, color, and brightness. The 3D pixels then lie on a Z-axis. When the pixels are combined with their depth, it will result in a 3D surface, also called a texture.

3D Films - 3D films are motion pictures that have 3D depth on them. With the help of 3D glasses, we can watch a 3D film. To make this kind of film, creators use stereoscopic vision, which means two images are shown simultaneously, each for one eye.

3D Printing - 3D printing is also known as additive manufacturing. It is a process of making a 3D in solid form from a digital file. Using a Computer Aided Design (CAD), you can print a 3D object from a digital model.

Del 2. Sådan afspiller du 3D-film

Nu hvor du kender 3D-betydningen, lad os vide, hvordan man afspiller 3D-film ved hjælp af det mest fremragende softwareprogram, du kan bruge.

Blu-ray Player er et skrivebordsprogram, hvor du kan afspille enhver type video. Med dette værktøj kan du også afspille 3D-film uden at bruge plug-ins. Derudover anbefaler mange mennesker denne medieafspiller på grund af dens enkle og rene brugergrænseflade. Desuden kan denne kraftfulde medieafspiller afspille Blu-ray-diske, Blu-ray-mapper, DVD/mappe/ISO-filer, som andre medieafspillere ikke understøtter. Du kan også nyde at se HD-videoer med 100 procent tabsfri lyd og dramatisk HD-surroundlyd. Hvad der endda er fantastisk er, at du kan oprette din afspilningsliste, så du ikke vil have svært ved at adskille de videoer eller lyd, du ønsker.

Sådan afspiller du en 3D-film i Blu-ray-afspiller:

Step 1. Download Blu-ray Player on your device. Follow the installation process, then run the app.

Step 2. On the software’s main interface, click the Open File button. Your device’s files will appear, where you will select your 3D movie.

Step 3. Then, your video will begin to upload. You can now wear your special 3D glasses and enjoy watching your 3D movie.

Del 3. Hvad er 3D TV og 3D Briller

Der er to typer 3D-tv: Active-shutter 3D, Active 3D og Passive 3D. Denne del vil skelne mellem deres forskelle og bestemme, hvilken type 3D-briller der skal bruges, når du ser Active-shutter eller Passive 3D TV.

Active-shutter or Active 3D is a type of 3D TV that displays high-quality 3D images alternately on the screen. Active 3D TV displays alternate images on the screen for the right and left eyes. The 3D glasses then shutter black alternately to portray the 3D effect seen on your TV screen. This causes each eye to see the image made for them. The 3D glasses you must use when watching in an Active-shutter 3D are 3D active glasses. This type of 3D glass needs a battery that it uses to block and shutter the lenses on the glasses electronically. These glasses are incorporated with LCD lenses to coordinate with alternating frames.

In contrast, Passive 3D TV is somehow similar to the 3D technology that movie theaters use. This type of 3D TV uses special filters on the screen to see 3D using polarized lenses in the glasses. Furthermore, Passive 3D TVs blend the two frames in one, alternately between the horizontal lines for the left eye and right eye. The glasses that these 3D TVs use are Passive 3D glasses which contain different polarization on each lens. The other eye only sees the odd lines, while the other sees the even lines to produce a 3D image. The Passive 3D glasses do not require batteries to work.

Del 4. 2D vs. 3D

2D og 3D er faktiske dimensioner i et computerarbejdsområde. 2D eller todimensionelle er flade objekter, der bruger de vandrette og lodrette dimensioner (X- og Y-aksen). Da 2D kun har to dimensioner, vil du kun se en streg, når du vender dem til siden. Den har kun en højde og bredde, men har ikke dybde. Mens på den anden side, 3D eller tredimensionel indeholder højde, bredde og dybde. Tredimensionelle billeder har brug for effekten af to øjne, der arbejder sammen for at se en tredimensionel perceptiv. Hvis 2D bruger X- og Y-aksen, tilføjer 3D Z-dimensionen, så du kan se et objekts dybde.

Hvis du spørger, hvad der er godt at bruge, 2D vs. 3D, er svaret begge dele. 2D og 3D har forskellige fordele og ulemper. For eksempel kan du se 2D-videoer eller -film hvor som helst på enhver enhed uden at bære særlige 3D-briller. Den 3D-effekt, som 3D-film producerer, er dog forbløffende og sjovere at se end 2D.
