LLG Python Geometric Computing in Python for New Generation Gaming • New questions in terms of architecture, design and development. Parallel processing hardware Storage capabilities Online gaming Mobile devices
• Proposing original, Python based solutions Unifying volumic data representation and processing for real time applications
• Client side
Newcoming Challenges Parallel Processing and Multicore Hardware
Multicore everywhere! • High-end GPU • Mainstream CPU • NextGen Gaming Consoles
Long lost expertise… • Rough implementation problems • The difficulty to port some applications
As many problems as there are applications • Physics, geometry (AI), graphics… • The interoperability problem
• Server side
Newcoming Challenges Parallel Processing and Multicore Hardware
Once upon a time… • Precalculated sequences • Preprocessing

Newcoming Challenges Storage Capabilities
From cartridges and floppies to DVDs and Blu-rays and on… Ever expanding costs • Difficulty to rationalize production risks • A shift towards episode based sequels (Half Life 2 and others)
How to create such an amount of content? • Video is not enough • GTA 3 fits 17 square miles (44 km2) on a single DVD • Tomorrow, design and produce up to 500 km2 on Blu-ray?
Up to 50 gigabytes of data in early 2007
Newcoming Challenges Online Gaming
• Server side User Modifications • Maps, graphics etc…
The MMOG problematics :
Collaborative content Second Life
• Collaborative environments • Maintenance problems : How to patch your greens? World of Warcraft (Almost) Weekly Patches
• Through the looking glass
Reduced memory Reduced CPU power Weak floating point capabilities Networked devices
• A difficult equation
Heterogeneous offer How to make the best of capabilities and overcome limitations? Market still very much unstable

Where do we come from
• Montreal University – 1991 to 1995 Desargues Project • Arithmetics of Forms - Joining topology, arithmetics and lambda calculus • Implementation based on functional programming Scheme • Parallel Computing – Developments on Archipel Transputer Systems
Thesis • Dr J. F. Rotgé - “L’Arithmétique des Formes - Une introduction à la logique de l’espace” – July 1997
Where do we come from
• Arithmetic of Forms Unifying Topology, Arithmetic and lambda calculus
• Projective Geometry and Unconditional Programming Introducing a superset of Euclidian and other conventional geometric systems Eliminating geometric special cases, i.e. testing and conditions Generalizing homogenous coordinates : Integer based, No loss of precision
Where do we come from
• SGDL Systems – 1995 to 2005 Applying research results and Arithmetics of Forms to industrial applications Focus on Applications / Proofs of concept for hyperlarge scenes Scheme based implementation for mainstream systems
Who we are
• Parallel Geometry – 2006 Focus on High Performance Computing and Hypercomplex Simulation Applications • Systems Architecture • Software Optimization
