Omnity Camera System for Immersive Projection

This extension requires one license per seat. Requires Unity 5.6 or higher.
Omnity allows efficient real-time correction of 3D content onto spherical screen surfaces. Compatible with Unity v2 post-processing effects, LWRP and HDRP. v1 post-processing effects are not compatible.
Developed by immersive projection veterans The Elumenati, and designed from the ground up to enhance usability and performance, Omnity is a class that converts Unity's camera into a spherical camera for projection mapping onto domes, cylinders and similar “group VR” type displays.
Features include:
+ Simplicity, just drop Omnity.cs onto your main camera in Unity
+ Build for Windows with advanced capabilities
+ Highly configurable for advanced users
+ User-optimized view frustums for user-defined screen shapes and system configurations
+ Modify default settings at build time, and tweak them at runtime
+ Equirectangular output capable for VR compatibility (registration required)
+ 3rd party multi-channel camera calibration systems compatible (premium feature - requires additional per seat runtime activation, plus supported 3rd party camera calibration system from Vioso or Scalable).
Registered users receive additional preset screen config files, post processing script, support resources, and the ability to enable runtime activation of advanced features.
