What is a volumetric image?
A lot of VR experiences and imagery is being shot with a 360 degrees image, viewers watching would be dropped in the middle of the scene and are able to turn their head, but have no choice from which angle they want to watch. A volumetric image is an image in 3 dimensions. 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.
Render any scene with PresenZ easily
With the implemented plugin for Vray in 3ds Max , or Arnold for Maya you can render any scene with PresenZ with a single click. Simply place a PresenZ camera in your scene and hit render. PresenZ can handle very complex scenes so the user doesn’t have to compromise with quality. He can render the highest quality assets and reuse assets that were created for standard movies.
More render engines and 3d software plugins are coming in the future as we continuously improve and expand PresenZ.
PresenZ and the Zone of View
PresenZ makes a render from a zone of view and gathers all the information which is possible to see in this “zone”. The ZOV is a volume box with a default size of 1 by 1 meter with a height of 0,5 meters, but this can be adjusted according to preferences.
While the user is inside the ZOV, he/she can look in any direction they want. When the user is outside of the ZOV, it looks like he is watching through a portal which is projecting the 3D scene. The ZOV position and orientation is given by the rendering camera in the 3D scene.
A solution for a bigger zone of view: Multibox
To render very large volumes 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 a seamless transition at playback, or separated, allowing the viewer to walk or teleport from one zone of view to another.
This is easier on your computer as it will only compute the current box you are standing in at playback, instead of one very large zone of view.
Compositing and Grading
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.
- Rendering out an object separately and merge the object in your complete scene without having to render out the entire project again.
A Houdini plugin for post production is coming soon.
The Watermark on your volumetric images
You can try the 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 you can do so inside the PresenZ dashboard/viewer, by spending credits bought on our webshop. One credit removes one watermark.
It’s important to note that we do not upload any of your images, we only get the hash. This way your scenes and PresenZ renders stay confidential.
PresenZ uses binaural audio
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.
PresenZ uses the file format .tbe (Two Big Ears) which you can export using the free encoder that comes with the spatial workstation from facebook360.
For an immersive experience, your PresenZ render and audio can be combined at playback.
Viewer feature: Free Roam
Previously, the user was restricted to the Zone Of View. The Free Roam feature 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.
