Everything you want to know about 3D, but you never dared to ask

It’s appropriate for every article to write an introduction, so I won’t miss that now. Though I’d ​​love to miss it, my fingers are bubbling with so much to say in recent months about the 3D rendering. I will restrain myself, but only until the next page.

Before we look at how three-dimensional visualization is, let’s jump back to the past. This cannot be avoided, as the currently used solutions of the spatial image were not born today, moreover, the spatial effect did not enter the visual world for the first time.

Anyone who didn’t start dealing with computing yesterday knows that the first 3-dimensional experience is tied to sound. The memory is still vivid in me when I inserted the first sound card with the 3D mark on the box. True, these cards were just stereo, but with some software tricks, they were able to produce surround sound. I remember the feeling it was like when I started the demo, I closed my eyes and a fly (?) Flew around my head. It was a wonderful feeling.

In just a few years, the image has risen to the third dimension NVIDIAusing. All it took was a pair of glasses, which we connected to the video card with a cable. The only problem was that at the time, most CRT monitors still had a 14-15-inch diagonal, and to get a flicker-free, three-dimensional image, the resolution had to be reduced to VGA. Today, it’s also fun to say that I was playing at a resolution of 640 x 480 with the current car racing game or repsulator.

I had that too…

Although my head ached soon, the experience made up for it, as the boards really hung over the road and the waterfall also looked pretty good.

One more thought at the end of the introduction. Once, for many years, there was an exhibition in the castle, Buda, where you could see holograms. Although not a child, I was still very young and I was impressed with the exhibition. Back then, I didn’t know how much I had to wait for my display to be 3D one day. What’s interesting about it is that to this day I don’t know when I’ll be able to sit in front of the TV without glasses to see things in space like the holograms in that very old exhibition.
