Reality Engine® uses Unreal Engine by Epic Games, the most photo-realistic real-time game engine, as the 3D renderer. With the advanced real-time visual effects capabilities, Reality System ensures the most photo-realistic composite output possible.


Tracking Technology and Lens Calibration

Reality Engine®, the broadcast compositing system supports industry standard mechanical and optical camera tracking systems. Reality can use the lens calibration data sent by the tracking devices.


Talent Tracking

When the talent tracking data acquired by Reality Engine, the engine positions the talent inside the virtual world in the correct position and depth. This technology automatically enables the creation of accurate reflections and refractions of the talent. Interaction between the real and physical is achieved with utmost realism thanks to Reality Engine’s industry first and only feature of compositing in 3D space. All process happens in one single machine.

Compositing in 3D space

As a unique approach in the market, in Reality, green screen image is composited with graphics in 3D scene. This technique results in real-time realistic reflections and refractions of the physical objects and the people inside the green screen on top of the graphics. Also blooming effects and lens flares are composited over the real elements. All of the compositing is made in 16 bit floating point, for HDR precision.
