Press Releases

domeprojection.com® revolutionized the way optical blend masks are produced

The first demonstration of NBlend Optical Blend System by domeprojection.com® was received enthusiastically at I/ITSEC 2016 in Orlando. In an interview Christian Steinmann, Managing Director of domeprojection.com® explains how they got the idea for NBlend, which difficulties they faced during the development and why NBlend is a revolutionary product.

Berlin / GERMANY, Dec 14, 2016.  Most of today’s projection technology cannot display pure and smooth black. This leads to visible light grey areas in the overlapping regions of multi-channel projections. While the effect is hardly visible when day scenarios are projected, it becomes a major disturbance when dark content and night visuals have to be displayed. The best way to get the overlapping areas under control is the use of so-called optical blending masks.

What does domeprojection.com® do?
domeprojection.com® (Berlin/GERMANY) develops Hi-End Automatic Projection Alignment and Calibration Technologies for Visual Display Systems for professional Simulation- and Training environments, Fulldome, Planetarium and Media Based Attractions.

Why NBlend Optical Blend System?
We´re an innovative company. Our goal is, to find solutions for the needs of our customers. Especially our clients that are involved in simulation have the need for perfect black level blending. However, up until now there was no simple cost-efficient solution to that. To the contrary, you had high costs and long adjustment periods, while at the same time the results were often not satisfactory for the customer. We set out to solve these issues. The result is the newly developed optical blend mask solution called NBlend Optical Blend System.

What makes NBlend so special? What´s the revolution?
The basis for NBlend is a full calibration of a projection system including the blending plane, in which the optical blending takes place. Using the calibration data, the optical blend mask is calculated for the actual projection system as it is set up. That sets it apart from previous solutions. There only the theoretical design data was used to calculate the blend masks. This is a problem, because it is impossible to build the projection system, staying true to the design with sub millimeter precision. In summation all the slight deviations would always introduce severe artifacts in the blending result. That is why after the installation a time consuming and expensive readjustment of the position and orientation of the projectors and blend masks was necessary.  The biggest achievement of NBlend is to render these readjustments unnecessary. The second achievement is the unprecedented blending quality in light projections. This is a major challenge, since the smallest blending errors lead to severe disturbances in the projection. For this reason, optical blending wasn’t used for day flight simulations in the past, which in turn made smooth transitions from day to night in one training session impossible. With NBlend that is now possible.

Which difficulties did you face during development?
First we had to understand how the projectors light field interacts with the optical blend mask. When we thought we had it all figured out, we saw that the pattern of the blend mask had to be different for each projector type depending on its light engine.

For which field of application would you recommend NBlend?
Our target Markets are Civil- and Military Simulation and Training, Planetariums and Dome Cinemas, VR Centers, Theme Parks and Dark Rides as well as Culture and Entertainment Attractions. Where ever outstanding contrast in dark projections is required, NBlend is the solution.

When did you present NBlend the first time?
NBlend was presented at I/ITSEC 2016 in Orlando, for the first time.
For the demonstration, a separate dark room was reserved. Invitees were introduced to the technology in a 4-channel projection setup flying in a seamless transition from night to day via dusk and dawn to experience the excellent blending result using NBlend. The IG was supplied by Quantum3D using their IDX80 (hardware) and Mantis (software).

How was the feedback of the participants?
We got really good feedback on the new technology. Partners, customers and also long-standing experts were impressed. That’s amazing and makes us proud of our work.
