Meet the Team – Peter Sinclair

In this blog we talk to Peter Sinclair, a new addition to the team at GBvi – Peter has joined us for the summer before he returns to his studies:

 

What are you studying?
I’m currently studying Computer Science and Software Development at Sussex Downs College in Lewes. It is a radical change for me, as I was previously working as a camera operator and camera assistant for films. I’ve always wanted to do something more academic and I have been enthusiastic about computer technology for many years. I thought these courses would give me a great chance to turn my nerdy obsessions into something useful! I’m also working with a friend of mine who specialises in modelling historical buildings in 3D to create a virtual reality experience of an experimental WW1 airfield for a client. It’s fun, as I get to hone my coding skills making a Vickers Vimy bomber fly with the control of a player.

 

Tell us a little about your role at GBvi?
I think ‘roles’ is a more appropriate term, as I’ve been doing a little bit of everything! I have done many things ranging from tidying the warehouse, sorting tools, bolts and screws, bug testing a projector rig, building projector assemblies and much more. No two days have been alike so far, which I highly enjoy. I’ve also kindly been given control of the radio, so Classic FM has been reigning supreme. It’s probably the most civilised warehouse for miles around.

 

What excites you about the projects/applications GBvi is working on?
I love how specialist and unique Gbvi’s projects are. I find it incredible that the team works with clients all over the globe, each with their own individual needs. I’m also impressed by the level of technical skill and knowledge that goes into their work, especially in craftingblend masks. It’s been fascinating hearing how they make everything function and I feel like I’m learning more each week. I’ve particularly been intrigued with the coding that goes into making their projects work. It’s nice to see how the concepts I’m learning at college are applied in a real world situation. More than anything, I appreciate how friendly everyone is. They’re a really nice team to work with and are always happy to answer questions.

GBvi’s Geoff Blackham to Speak at Display Summit 2017

GBvi’s founder and director, Geoff Blackham, has been announced as a speaker at this year’s Display Summit, organised by Insight Media focussing on the technologies, issues and opportunities for projection-based and body-worn immersive display systems in training, simulation, visualisation and entertainment applications for commercial, military and professional markets.

This means flat, curved and domed projection-based simulators, trainers, theatres and 3D visualisation solutions as well as body-worn immersive solutions using virtual, augmented and mixed reality.

The event will be technical in nature with attendees and speakers coming from:

  • Professional projection, LCD and LED component suppliers
  • Professional projection and LCD and LED manufacturers
  • Training and simulation integrators and manufacturers
  • 3D visualisation integrators and developers
  • Domed theatre developers and suppliers
  • AR, VR and MR developers and manufacturers
  • Advanced display developers (light field, holographic, volumetric)
  • 4K+ connectivity providers
  • 4K+ hardware rendering providers
  • Government and military end users
  • Professional and commercial end users
  • Universities and technology development centres

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.

David Cotterrell’s 2nd Exhibition of Mirror III using GBvi’s VOID comes to close at Danielle Arnaud, London

For his fourth solo exhibition at the gallery, David Cotterrell presented three works from the Mirror project: a series of two-screen works produced in collaboration with Ruwanthie de Chickera at London’s Danielle Arnaud Gallery.

The travelling exhibition was open from 25 February to April 1.

Mirror III: Horizon examines what might transpire between two strangers if their communication was reduced to the language of lights. Filmed in Malta, set against the dramatic edges of the island’s stunning coast and contextualized by the island’s deep historical experience of visitors who arrived repeatedly by sea, the installation draws on the fluctuating paranoia of the current refugee crisis. Mirror III examines what might possibly be communicated between strangers if their words were reduced to beams of light and their faces need never be revealed.

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.

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.

“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.

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.

Meet the Team – Paul Blackham

paul blackham gbvi projector edge blending.jpegIn this blog we talk to Paul Blackham, Developer at GBvi – he’s not always in a client-facing role, but all of our customers and projects certainly see and benefit from his expert programming skill.

So, tell us a little about what you do at GBvi

A major part of what I do is to develop the design tools we use during the early stages of each project process – the ones that help map system design and accurately produce layout data for our customer projects. Occasionally I work on system blending designs too and am increasingly working with the team to gather data for various projector models that we can use in blend analysis.

Typically, what’s your involvement in projects?

My involvement in projects usually depends on the scope of the client requirements. On some projects, we play a key part in the design optimisation process of the display system, helping the client to build and specify the optimum configuration. On others, we are contracted to design and supply an optimised blending system where the client has already signed off on projector layout.

What’s your background?

I have a degree in Games Art and Design, so not really from the sim or viz industry as I know it now, but I still find there’s a huge amount of overlap and similarity in the worlds of simulation and gaming. I’ve spent a lot of time with CAD software, 3D modelling and programming which has really been put to use here.

Tell us about the kind of projects you work, and what you’re most proud of

Unfortunately, we’re unable to mention the specifics of many projects we work on for obvious reasons. Recently though, I’ve been working on the delivery of a project for a search and rescue helicopter training programme. As a display system, it’s actually pretty complex with 11-channels of projection. I’ve recently developed new design tools that have overseen the entire project for us from initial design process through to completion – the creation of the masks was then handled by our usual in-house team.

What keeps you on your toes at GBvi?

We’re always testing the compatibility of projectors which can be a little challenging. If we receive a new enquiry that specifies a model of projector that we haven’t tested before, it’s not simply about pricing something up. It can mean the start of an R&D project where we often have to simulate the client environment by bringing in new screen shapes or material. We need to ensure our performance specification is accurate first time around and have to go the extra mile to achieve this.

What do you enjoy most about working here?

I find it really enjoyable to get into the programming side of things, particularly seeing how the tools I develop consistently produce high standard results and streamline the process. Plus, we have a great office in the Sussex countryside, yet I’m still able to live right on the beach in the bustling city that is Brighton.

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/
