  1. PGP Grid NeSC Review May 2005

  2. Description and Aims • Apply real time 3D vision technology to animation production. • Apply remote parallel processing to real time 3D vision. • Apply remote parallel processing to hyper-realistic rendering of imaginary environments • Propose best practice for Animation Virtual Organisations

  3. Description PGP Ltd WP1: VO Study WP2: Capture of sequences WP6: Distributed Rendering WP3: Specialisation of software WP4: Grid enabling S/Correlator EPCC Glasgow WP5: Image streaming

  4. Status • Project completed at end of 2004 • Remaining activity since then limited to preparation of journal articles and final report.

  5. Achievements • EPCC: • Produced Virtual Organisation report • Built Resource Locator for Parallelisation • Developed a Remote Rendering Service integrated with 3dStudio for PGP • GU : • Developed parallelised matcher based on Pi calculus • Integrated and tested Pi calculus system with EPCC resource locator • Set up a resource locator server at Glasgow • Developed video sequence conforming software • PGP : • Built CGA sequences using material produced by GU • Jointly developed approach to remote rendering of sequences

  6. Dissemination • GGF-March 2004 • Presentation to All Hands 2004 • Award of A H Reeve Premium by IEE in Jan 2005 • Presentation to be given to 2nd International Workshop on Middleware for Grid Computing, in Toronto • Demonstration given to Pinewood Studios of the animation technique • 2 Presentations to ITI Techmedia • Papers published – see subs page. • Code and documents available from website.

  7. Papers published or accepted • 3D Performance Capture for Facial Animation, MacVicar, D.W., Ford, S., Borland ,E., Rixon, R.C., Patterson, J.W., Cockshott, W.P., 3DPVT, Thessaloniki, Greece, IEEE Computer Society Press, (2004), ISBN/ISSN: 0-7695-2223-8 • The PGP Grid Project, Cockshott, W.P., Yarmolenko, V. Mackenzie, L. Borland, E. Graham,P. Ju,X. , All Hands Conference, Nottingham, (2004). • JPIE INTERFACE: A Java Implementation of the PI-Calculus for Grid Computing, Yarmolenko, V., Cockshott, P., Borland, E., Mackenzie, L., Graham, P., Proceedings Middleware Grid Conference, Toronto-Canada (Oct 2004) • Pre-commercial 3D Digital TV studio, Cockshott, W.P., Nebel, J-C., to appear in IEE Proc. Vision, Image & Signal Processing • Applying the Grid to Cartoon Animation , Lewis Mackenzie, Paul Cockshott, Viktor Yarmolenko, Ewan Borland, Paul Graham, Kostas Kavoussanakis, to appear in Concurrency and Computation : Practice and Experience.

  8. Exploitation • Presentation to Pinewood Studios. Possible use in Captain Scarlet. Need better handling of eyes and mouth. • We upgraded the handling of head pose and eyes in response to this. • Proposal to EPSRC for follow on project – rated of fundable quality but funds not awarded. • Development proposal to ITI Techmedia, this was rejected on the grounds that the world market for digital motion capture too small to justify the investment.

  9. Project Participants • PGP Productions Ltd: • Carl Goodman • Peter Stansfield (Wavecrest) • Glasgow University: • Paul Cockshott • Lewis MacKenzie • Ewan Borland • Viktor Yarmolenko • EPCC: • Kostas Kavoussanakis • Ali Anjomshoaa • Paul Graham • Gavin Pringle

  10. Technical Achievements – JPie • The versions of GridFTP available do not support memory-to-memory transfer, which is required by our application. • Lack of GridFTP server implementations on Windows has been a serious concern, with respect to cross platform use. This is especially the case when more than half the machines available to us are running Windows. • Further investigation revealed that the existing GridFTP protocols are not available in pure Java versions. We regard this as desirable to allow our matching harness to have a light software footprint on machines such as teaching lab equipment running Windows. • Milner’s π-Calculus provides the ability to transfer communications channels along communications channels in addition to image data itself, which is advantageous to our application for establishing dynamic data-flow graphs in the processing of image streams. • Resource locator incorporated into the Jpie system.

  11. Technical Achievements – ILS • As part of its code, each p-Calculus node can solve a problem or pass it to other, willing nodes to do it on its behalf • A node can pass its communications channels allowing dynamic configuration of data-flow graphs. • Lookup for willing nodes is done through our Resource Locator Service (aka ILS – Initiator, Locator, Servent) • A webservice that allows Servents to register with JPie and Initiators to locate Servents fulfilling their criteria

  12. Technical Achievements – ILS • Locator • Holds a database of resources • Hosts web services for updating and querying the database • Brokers resource requests • Servent (Server Entity) • Contacts the Locator with its resource description • Updates the Locator with its resource status • Initiator • Requests resource(s) from the Locator

  13. Technical Achievements – RRS • The Remote Rendering Service (RRS) is a webservice which allows the submission, control and monitoring of rendering jobs on a remote, 3D-StudioMax farm • This involves: • A user-interface integrated to 3D-StudioMax • Authentication at the remote farm • Seamless transfer of appropriate files to and from the farm
