HOW TO CREATE DOME CONTENT
By Jérémy Oury
Jeremy Oury combines audio and visual skills to make singular digital forms as architectural mapping, immersive projection, fulldome, light installation and original creation for theater. Since 2014, his artwork was awarded in various international video mapping festivals (FIMG 2015, Luz y Vanguardias 2017) and fulldome festivals. His work has been shown in many exhibitions as Mutek MX 2022, Mapping festival 2021, ISEA 2019, FILE festival, Domo Lleno, MADATAC, and many others.
He produced 5 short dome movie and actually he works as dome specialist for a long fulldome movie. He also co-create the first fulldome festival in Paris "Sous dome" at Universcience.
This topic was discussed during a working group in the IBSIC/Video mapping festival 2023 in Lille.
1/ TO DO WHAT
Immersive projection at 360° with immersive sound system
Emersive / ARCAAN Collective & Jeremy Oury / Festival FDUK - UK & Domo Lleno (Col)
Live artistic immersive experience
Entropia / FRACTION / SATosphere (Ca)
2/ 2 families : planetarium VS geodesic mobile dome
Initially for science and astronomy content VS digital art festival
A lot of planetariums were built around the world since the 1930s. They are scientific and astronomical places with analog projection systems.
Today, more and more planetariums are equipped with modern projection systems allowing to play video in real time and facilitating their punctual use as a place for digital art.
Now, many festivals organize projections of abstract films and performances.
In the same way, mobile geodesic domes are sometimes installed in the public space by certain festivals.
The first planetarium dedicated to digital art is the SAT in Montreal.
3/ Different seating situations
Planetariums are interesting architectural places and they all have their own particularity.
without seat option (a) :
ideal to configure the place as you wish, to imagine a total immersive space where the spectators can lie down or walking in the dome. It's ideal to perform in live.
No axis or point of view imposed to the spectators.
circular option (b) :
Multiple viewpoints depending on the position of the spectator.
frontal (c) and frontal tilted (d) :
Frontal axis imposed. And a shift of the horizon is possible with the inclination of the dome.
4/ DIFFERENT DOMEMASTER PICS
The main format is a spherical image embedded in a square format 8K - 8192 x 8192 or 4K - 4096 x 4096 with a square pixel Aspect Ratio (1:1) and a frame Rate at 30.00 fps or 60 fps
The Master files could be shared as :
Different types of spatial distortion can be taken into consideration - depending on the result and the effect you want to achieve in the dome.
Spherical reference / Cylindrical reference / Cubique reference
5/Creative process - 3D
Cinema4D (Native camera)
Export as spherical camera enabled and with the dome FOV. But C4D gives you a equirectangular video with only the top part (which is the upper hemispheric part that you can use for the dome).
You must convert the equirectangular video as dome (with AE VR converter effect for example)
Cinema4D (Blendy360cam additional plug in from https://blendy360cam.com)
This plug-in render directly a domemaster file.
Blender (Native camera Panoramic/Fisheye with Cycles)
6/Creative process - 2D
From Equirectangular to fulldome (using a the superior part of a 8192x4096 equirectangular canva)
or directly in spherical format (kaleidoscopic effect or circular draw pattern) :
7/ From live captation
with VR camera device like insta360 pro or any devices with fish eye camera (A stitching step could be necesary).

8/ Spatial immersive sound
Sound is mixed in a virtual 3D space where you can put virtual speaker to generate each sound elements. You could have a render of the global sound with immersive, ambisonic or binaural device.
From this mix, you can downmix it in : Mono, Stereo, binaural, 5.1, 7.1, 5.1.2, 7.1.2, first-order ambisonic (FOA) or higher-order ambisonic (HOA), etc.

9/ Format specificity
Movements
Anticipate movements in the domemaster's periphery: the larger the dome, the greater the distances covered in the dome.
Decide on the point(s) of attention - pay attention to the distance between them.
Pay attention to the start and stop of the movements to avoid the motion sickness
Luminosity
Keep the background dark and create high contrasted scene.
Images near the zenith produce less parasitic light since images near the periphery.
Free tools from Nest Immersion :
FOV - field of view
Sometimes you have to cheat with the horizon by moving it up a few degrees (here 10°) so that it is visible in the dome.
10/ Complicated simulation of dome ?
It is difficult to interpret and extrapolate the result of what you are doing on your flat screen in a giant 360° immersive dome. A few options exist:

11/ Ressource website
https://www.fddb.org is a database site regrouping all the places of diffusions (mostly planetariums), films, artists and events.
We can see that the classic dome contents (scientific, for children, astronomical) dominate but little by little, more and more immersive experiences of abstract art and digital art appear.
