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.
