Live Capture vs Rendering for Virtual Reality

Live Capture vs Rendering for Virtual Reality

As we have covered in previous posts, virtual reality production is broken down into all sorts of different tech specs. From resolution to viewing angle and 3D or 2D, you’ll find a handful of key specifications, each of which plays a part in your interactive experience. However, in terms of the kind of content you see, there really is just two (at least under the veil definition of virtual reality). The first is virtual reality live capture and the second is computer generated rendering. Currently, all of the content you see on VRHush is live capture, but understanding the difference between these VR variations can help you discover new forms of entertainment.


Virtual Reality Live Capture

This is the kind of VR you’re experiencing when watching the quality content on VRHush. The video is recorded using a specially designed camera configuration. Now, there are a few different variations involved with this kind of virtual reality live capture method. The first is where you watch the production unfold in front of you, similar to that of a traditional movie. The only real difference between this and your movie theater viewing experience is you can turn your head in any given direction and your field of view changes.

There is a more physically interactive offering that falls into the virtual reality live capture format. This is where you can move about a given room or space and react to what you see. Usually you will need a more extensive VR setup. There are systems where you can create room barriers so your hardware can identify how you’re moving through the environment. Many athletic teams use this kind of video virtual reality experience to help train players during the off-season. Some NFL and even college football programs have VR setups for quarterbacks where they can take their place under center and reach to different defensive alignments brought against them.

Computer Generated Rendering Virtual Reality

Think of this more as the video game format of virtual reality. With computer generated rendering, the entire experience is produced on a computer. So, whether you want to look at it as stepping into a computer generated animated movie or just having a video game completely envelop you, instead of being a flat surface in front of you, this is what the computer generated rendering virtual reality is.

Like the video recording, there are some VR videos that are just sit and watch while others are interactive. Generally, these are more of the interactive variety simply because everything within the scene is created on a computer, which means it is easier to promote interactions with generated material found in the scene.

Combination of Live Capture and Computer Generated Rendering

The combination of these two formats is starting to become a bit more popular, but you don’t see it all that much in virtual reality. Augmented reality is a format where computer generated material is placed over your physical view. This is where you will more commonly see the mixture of video and computer based content. The new Pokemon Go! App is one example of augmented reality. When you want to capture a Pokemon, you load your app and point the cell phone’s camera towards the location of the Pokemon. The computer animated object will appear on your screen, as if it is standing in front of you. Your viewing angle of the Pokemon will change as you tilt the phone and move around. There are other kinds of augmented realities, but as the merging of live capture and computer generated rendering moves forward, it will stem more from augmented reality.

So how does the combination of these two different formats come together in actual virtual reality? Similar to that of Pokemon Go!, the scene itself can be recorded via a camera setup while a handful of computer generated objects are created and placed into the VR video. Perhaps if you are into animated porn, this makes it possible to enjoy a cartoon within a video captured world. The merging of the two formats does take more time during postproduction. Not only does the computer generated material need to be included in the video, but also it needs to be anchored properly. This way, the content appears sitting on the floor, table or wherever it needs to be in order to maintain a sense of realism. On top of that, it costs more money to produce as it increases file size, rendering time and man hours to produce. Due to this, you’ll likely find high-end computer generated virtual reality, or merged formats, far more expensive than just live captured virtual reality.

The Future

There really is no telling exactly the direction virtual reality goes. You will likely find more and more augmented reality situations or the merging of both formats. However, one will not dictate over the other. Each form of virtual reality provides you with a different experience, so until computers are able to perfectly replicate the appearance of the human form (without costing tens of millions of dollars), you will have access to both VR formats.

While virtual reality has been around for decades, it is just taking off for the average consumer. This gives you a world of opportunity to test out, experiment and explore all the different forms of entertainment available to you. It really is like stepping into brand new worlds, every single time you put the headset over your eyes. So, whether you’re about to pop on your new PlayStation VR headset and dive into a new computer rendered world or you need some personal time with one of our beautiful porn stars, there is always going to be something exciting to check out. Your next VR experience awaits.
