180 SBS (side-by-side). It's the format most "VR porn" is produced in, and what those cheap-o smartphone VR headsets are most suited to display. It's basically two images (or videos), one next to the other (horizontal is the most common; certain players can use vertically-oriented material, too). Each image is almost identical, but rendered from a _slightly_ different perspective, in order to simulate the difference in perspective between what you see from your left and right eyes. When viewed on a traditional monitor, they look weird; just two nearly-identical images. But when viewed with a headset and the correct software, then either side of the image can be seen by only one of your eyes at a time - fooling your brain into thinking that you're standing in front of a genuine 3D object. (this is basically how VR headsets work, most of the time - they split videofeeds into two channels, and then send a channel to each of your eyes; 180 SBS is just that minus the interactivity)

For viewing, I use an HTC Vive headset with Whirligig, an inexpensive media player available on Steam. You can get such images and videos to work on any headset, though: smartphone headsets, Google cardboard, etc.

Like I said, it's not too hard to get the hang of it; it didn't take me too long to grasp the basics, and I'm HORRIBLE with CGI...! There's even freeware video converter software that can change standard 2D images and videos into 3D stereoscopic stuff, but I have to warn you, the results usually aren't very good - it's far better to render your picture/video in SBS from the beginning, while you have full control over your camera position, because otherwise you'll be at the mercy of software AI and it can be VERY difficult to get objects to display at their proper depth.
