Frequently Asked Questions

What is a 6DOF Volumetric Image?
A lot of VR experiences and imagery are 360 degrees images. In those 360 movies, the viewer can look in any direction, but the head movements wont be taken into account, leading to poor immersion and cybersickness. A volumetric image is an image with 6 degrees of freedom (6DOF). The viewer is able to move inside the image, get closer to objects or characters, and even look behind them. Objects that were previously hidden to us, now become visible. You are able to become your own cameraman inside the movie. Creating a deeper sense of immersion inside the scene and a perfect comfort in VR.

What is the V-Nova PresenZ Pipeline?
You can reuse your old assets. The authoring tools allow you to create volumetric images in the V-Nova PresenZ format. With these tools you replace your existing camera with a PresenZ camera. You will use this camera for your new render. The render time is usually twice the length of a 360° stereo render. This can of course variate on the complexity of your scene. Afterwards The Dashboard/Viewer allows you to visualize your V-Nova PresenZ images.

What is a the Zone of View?
Usually a rendering is done from a single point, known as the Point of View.
V-Nova PresenZ makes a render from a Zone of View (ZOV) and gathers all the information to cover whatever is visible from within this "zone". The ZOV is a volume box with a default size of 1 by 1 meter width and a half a meter height, but this can be adjusted according to preferences.
The user can move freely inside the ZOV and look in any direction.
The ZOV position, orientation and size is defined by the author in the 3D scene, it replaces the standard perspective camera.

In the normal operation mode getting outside the zone of view will blur the image until the user gets back into the boundaries. The other operation is Free Roam.

What is Free Roam?
Previously, the user was restricted to the Zone Of View. The Free Roam feature in the PresenZ Dashbord/Viewer allows the viewer to walk outside the boundaries of the Zone of View.
The viewer then fills the missing geometry with colors matching the closest neighbors.
While the experience is optimized and best viewed from within the Zone Of View, this allows the user much more latitude in it's movements.

How big can my Zone of View be?
The bigger the zone of view, the more data we have to collect and manipulate.
To render a very large zone of view without any performance issues, we created the multibox feature, which allows to subdivide the space in multiple zones of view. They can be either, one next to the other, with seamless transition at playback, or separated, allowing the viewer to walk or teleport from one zone of view to another.

This will be easier on your computer as it will only load the current box you are standing in at playback, instead of one very large zone of view with tons of data that might overwhelm the system.

What are these blue lines in my player?
You can try the V-Nova PresenZ tools for free, without time limit or registration. Which means you have the opportunity to make test renders and do multiple iterations on your scenes without having to pay each time you render.

The image will be watermarked by blue lines which move through your scene. If you wish to remove this watermark, contact us to get licensed PresenZ viewers or players;

Can I do any post processing / compositing on my PresenZ Image?
The PresenZ Merger gives you some options to modify your PresenZ file after the render. Giving you plenty of flexibility in your workflow.

Some of which are:

- The ability to color grade your rendered scene with an OCIO file.
- Use the V-ray color correction tools for your PresenZ images.
- Rendering out an object separately and merge the object in your complete scene without having to render out the entire project again.
- A Houdini and a Nuke plugin for post production is already available in private beta.

Can I play audio in V-Nova PresenZ?
With the use of a 360° binaural audio you can experience the direction and distance to the source of the sound. This way the user gets the sensation of actually being in the room of your 3D scene.

V-Nova PresenZ uses the file format .opus encoding 11 tracks;
9 Ambisonic 2nd order in AMBIX and 2 stereo head locked tracks.
Alternatively, it is also possible to just use 2 stereo head locked tracks.

For an immersive experience, your V-Nova PresenZ render and audio can be combined at playback.
