Geoff’s presentation, titled ‘Optical Blending for Maximising Dynamic Range of Projection Displays‘ will be given at 16:05 on October 4th, 2017 and has a published abstract of:

Quality projection displays for visual simulation have evolved to use mainstream commercial projection devices, which, together with automatic alignment solutions, have dramatically reduced time required for their installation, alignment and maintenance.  However, one bugbear has remained in the form of projector light leakage when displaying dark scene content.  Electronic blending solutions exist that produce excellent results for bright scenes but, for continuous background intensity levels in dark scenes, infill techniques are often applied, which can sacrifice up to 75% of the possible dynamic range. Optical solutions to blending multiple channels can solve this problem, offering the promise to increase the utility and hence value of visual simulation training substantially, yet often this option is not even considered – so why is this?

Optical blending implementations – which place physical masks in the projection light paths – have been around for a long time, but a universal solution for all projector types and scene content has yet to become available.  Many solutions give relatively poor performance that can be tolerated for dark scenes such as those experienced in night training, so are actuated out of the light paths for use with daytime scenes.  These present logistical challenges to simulator users, where a choice must be made as to what “mode” you are training, or some transition must be suffered while the blending system switches mode.  Other solutions cannot withstand sustained light flux without degradation, so again must be actuated, while yet others may cause image sharpness degradation in the blend regions, so must be designed very carefully to limit this impact, particularly with high-resolution projectors.

Included in this presentation will be a review of the mainstream projection technologies and their respective pros & cons, particularly with regard to scene dynamic range and blend implications. This in turn leads to a detailed review of optical blending options, presenting their operating theories and application scope.

GBvi Technology Helps Create Seamless View of Universe at South America’s First 8K 3D Planetarium

[press release]

Sussex, UK – 27 January, 2017 — In December 2016, the newly upgraded planetarium dome at Maloka Centro Interactivo in Bogotá, Colombia, reopened its doors after a state-of-the-art renovation project transformed the 18-year-old theatre into a Sciss Colorspace theatre, and the first 8K 3D planetarium in South America. The 5-channel digital fulldome experience uses GBvi Chronos glass plate blending technology to offer guests a truly seamless and visually stunning display.

Sciss, a leading vendor of modern fulldome and planetarium solutions and the award-winning Uniview software, had been contracted to replace the old iWERKS 870 film projector with their proprietary Colorspace solution featuring five Christie Mirage 304K projectors when they approached GBvi to design and supply high quality custom optical blends for each of the channels.

 

At 22 metres / 72-ft in diameter, the huge dome can seat up to 314 visitors each seeking a new perspective of the night sky.

 

Rob Overy, Senior Project Manager at Sciss commented; “The use of optical masks is essential in fulldome theatres where very dark scenes are common. GBvi’s Chronos offers the best optical blending solution for projected displays and their attention to detail resulted in no visible artefact, particularly within the irregular shape blend regions. It was a pleasure to collaborate with the team and to arrive at the optimum display arrangement for this dome theatre.”

 

Optimised for use within highly immersive and dark audience venues and visitor experiences, GBvi’s projection blending technologies have met stringent requirements as demanded by military and civil aviation simulation industries where accuracy, uniformity and true-to-life experiences are of critical importance.

 

Dan Blackham, Systems Engineer at GBvi noted’ “We had to align our design and supply process to very short turnaround requirements on this project. Working closely with Sciss and to the project schedule, we could ensure a right-first time glass-plate Chronos installation, supporting an on-time opening. We are used to working with complex display configurations, so welcomed this challenge from Sciss and their client.”

 

GBvi’s optical blending solutions are compatible with a wide range of projector configurations, brands and models.

GBvi VOID Infinity Experience Recreates Sublime Senses at Cotterrell’s Mirror II-Distance Art AV Installation

[press release]

Sussex, UK  —  12 August  — UK-based image innovation technology company, GBvi, has recently delivered two VOID infinity display experiences to a new art installation by renowned media and technology artist, David Cotterrell. The new installation work, Mirror II – Distance, is on show in Dublin as part of the Seeing exhibition at the Science Gallery.

 

David Cotterrell Mirror featuring VOID from GBvi
Mirror II – Distance is part of the “Mirror” project, a series devised to provide insight into global communities that experience distancing and objectification. It is inspired by observations of the Diplomatic Enclave in Islamabad and features two Pakistani guards standing and watching over the expat compounds they are stationed over. The two men observe each other across a distance as they listen to the visitors, the experts and the specialists discuss Pakistan, its people and its future.

 

The art installation comprises two VOID installations by GBvi, each presenting video media of a Pakistani guard communicating with the other in the secondary VOID. A suspended dome speaker above the installation ensures visitors only experience both sight and sound when underneath the audio and between each of the VOID stations.

 

Critical to the creation of the experience was a true and compelling sense of distance and infinity, so that the distance between the two guards feels true-to-life.

 

VOID, an infinity display experience for educational spaces, attractions and themed experiences, uses special display techniques and light path management to create extreme depth cues and illusions of distance – so that viewers and audiences are provided with a sense of peering into space.

 

Mirror II - Distance“It’s very difficult to transfer the sensation of place into reality. People can’t understand or recreate this experience from an illustration or image alone and we wanted to generate a sense of emotion and understanding from this installation. The VOID allowed us to do just that.” explains artist David Cotterrell.

 

“It was important that visitors became fully immersed and engaged with the media. We will continue to use this technology and refine how we apply it in future installations to continue innovating with depth cues and immersion in art.”

 

Available in a range of size, brightness, projection performance and playback configurations up to ultra-high contrast 4K, VOID is built to deliver realistic, immersive experiences.

 

Geoff Blackham, Managing Director at GBvi added, “It’s been a hugely exciting and eye-opening project for us, to see this technology being applied in such an innovative application. We have worked with David over many years – he is very experimental and inventive with his use of emerging technologies and we look further to further application of our products within his work.”

 

The launch of the Seeing exhibition marks the start of a two-year, multi-venue tour across the UK and USA. For more information, please visit https://dublin.sciencegallery.com/seeing/
