What’s it about?
• Creating interactive 3D simulations from textual descriptions of historical events

What’s it about?
• Creating interactive 3D simulations from textual descriptions of historical events
• Avoiding need for the creator of the simulations to be proficient in 3D tools

What’s it about?
• Creating interactive 3D simulations from textual descriptions of historical events
• Avoiding need for the creator of the simulations to be proficient in 3D tools
• We are developing tools that create:– scenarios– models of the objects the scenarios describe.

Where might they be used?
• Museum displays
• Historical web sites
• Education– primary– secondary– university

• A prototype 3D visualisation of a World War II sea battle

The narrative
• Extract from the narrative from which the simulation was generated :
::
At 06:12 Graf Spee is 12 miles from Exeter on bearing 320.It is on heading 120 at speed 15 knots.[Note: Graf Spee accelerates to attack causing a cloud of dark smoke which is sighted to NW by the British ships.]At 06:14 Exeter turns to heading 340.At 06:16 Exeter turns to heading 270.At 06:17 Graf Spee engages Exeter.At 06:20 Graf Spee turns to heading 090.

Deductive modelling
• The moment by moment movements of the ships are deduced from the narrative using information about the characteristics of the ships such as turning circles.
• The gun firing movements of turrets, guns, explosions, smoke, shell splashes etc are deduced from – the phrase “engages”– the characteristics of the guns and turrets (rotation
speeds etc)– the movements of the target ships

Edge Hill Project 1
• Create a viewer for the scenarios– the Builder tools creates viewer input files:
• specifying the scene graph and how it changes as the scenario runs
• model files (ships, landscape, buildings etc) written in VRML (Virtual Reality Modelling Language)
– the viewer:• generates the scenegraph using Python and Panda 3D• changes the scenegraph as time progresses• enables the user to change viewpoints at will

What you will learn?
• The agony and ecstasy of developing a full application– useful demo for your job interviews
• Using new technologies – any of ...– Panda3D– Python

Opportunities
• Improve the realism of the visualisation– shadows– weather– sea state– smoke– explosions– bow waves– ship wakes
