Key parts will be the construction and use of semi-immersive stereoscopic facilities to create an increased level of ‘presence’ within the Access Grid environment and the recording of the performance, in the same format, within a framework playable by a larger community base as and when required.

The project will have the following objectives;

Project Methodology

The main focus of the project is to construct best practice guides and recommendations for integrating portable stereoscopic display units either as stand-alone units or within VECs or within the AG or incorporated into a community lightweight framework.

With a growing list of evaluation partners two workshops are planned to promote the technology and exhibit its uses to a wide range of users.

Implications/ Deliverables/ Stakeholders

VRE project outcomes will be fully disseminated within both the technical fields of VEC publications and meetings as well as the AG community. Eurographics/Siggraph workshops and conferences, AG Retreats, SC Global and the Workshop for Advanced Collaborative Environments are all appropriate vehicles for demonstrating our achievements and recruiting users from around the globe. In the UK there are strong links held in the Eurographics UK Chapter that hosts annual meetings as well as via its members’ current research and non-research networks and projects.

More importantly is dissemination within the user groups’ publications, which is why a section of the budget is designed around workshops to aid research projects currently proposed by the core users. This will be used not just to promote the VRE directly but allow the facilities to be improved within the projects lifetime and beyond.

Schedule of Events and Disseminations

There have been eighty+ events distributing, both publicity and use, during the programme, to literally 1000's (although many, 450 where at one location). This has moved the sessions from purely dissemination to now use of the tools.

Full list (and growing) is avalable at /SageEvents

Documents have been created for a veriety of tutorials, talks and events and a selection are listed here:

Paper etc.

Academic papers have started to be published, more are expected:


Also there were a series of JISC VRE highlighted events and demonstration as well as the following two JISC sponsored articles,

A complete system for portable stereoscopic capture, processing and projection (exclusing polarizing presenving screen).

A lists of components follows:

Capture Systems.


Cameras shown are Sony Handycams - with LANC controllers (for remote/cable synchronisation) and have tripod screw mounting for two. Blackandwhite cable is main power; black cable is LANC syncronisation, red cable is fire-wire connection (for fast download from tape) and white cable is USB (for live streaming/monitoring).

Suppliers for the shown tripod mount and sync control is at:

  1. 3D Camera Slidebar Mount is $99.95 plus $5
  2. 3D Camera Remote $334.95

Projection Systems.

NEC LT 245 XGA 2200 Lumen projectors unit price £1340+VAT (x2 £3,149.00)

These projectors compromise between cost, brightness and ease of use, as well as not overheating. Two are required and a mount needs to be either constructed or bolted together - see below. The projectors use the DLP (Digital Light Processor) micro-mirror chips for a resolution of 1024x768 which has minimal interferance with the polarization process.

Used over a reasonable period - many hours - there does not appear to be any time dependent interfere with polarisers.

The lens have a 77mm screw fitting for filters or filter holders allowing very easy addition of polarised filters. Also, there is the cornerstoneing function allowing individual control (as opposed to keystoneing)

A custom built 'prototype' frame was built (£950). Other options are available.

MF&T, 22 Dawkins Road Industrial Estate, Poole, Dorset BH15 4JY 01202 666 456

Polarisation can be either linear or circular. For ease of replacement and general use as well as extenion three parts are required (all available frmo Jessops or other camera shop):

  1. Cokin Prof 77mm P Adapter - this fits on the NEC Projector (x2 £9.98)
  2. Cokin Professional Filter Holder Kit E240 (x2 is £13:98)
  3. Cokin Professional linear Polarization filters P160 (x2 £57:98)

A great advantage of these are that they are easily replacable, have reasonable quality and also the filters are positioned securely with easy rotation a few milimeters from the lens reducing overheating. A second possibly less useful advantage is that other filters could be added (to change colours etc.) although unsure why this would be required.

It is also possible to directly screw polarization filters on to the projectors. There is an unknown warning regarding heating of these filters. In the Cokin holder method, there is a layer (although very small) for air to crculate.

  1. Jessops Circular Polarisers 77mm - direct screw (each £49.99)
  2. Jacobs Circular Polariser 77mm - direct screw (each £46.90)

There is still a lot of debate over the advantages of linear verses circular polarisers. In terms of general quality they are very similar although linear 'should' be higher quality manufacture. But, circular allow for a degree of ratation of the viewer without loosing the effect, thus making them possily more comfortable.

The Cokin filters have started to burn - through the inner plastic layer - after long term use. This is due to heat. As projectors do not project through the centre of the lens - they project the image slightly off-axis - there is the advantage that any filter can be used in any of four different positions. This gives two different positions for each of the two different polarization states.

We are always reviewing different screens. Current material on the fixed installation 8mx2.5m from Virtalis is adequate but fitting is difficult and not perfectly smooth.

For portability we use various front and rear projection screens.

The Front Projection we used both a Harkness Hall screen - tight fitting, but reasonable quality (£771+VAT) as well a tripod stand with a 70 Silver Screen (£295 inc VAT) from The Widescreen Centre.

Rear projection system from Stewart is one of the best if you have the space and money (about £2K)


The following shows the complete portable system in use at the University of Bedfordshire for stereoscopic capture, compute and then playback - front-projection screen.
