Version 5.7 - New Features

Improved Realism of Road Traffic and Pedestrian Interactions

The central feature of this release is the highly improved realism of road traffic and pedestrian interactions including the following:

• Passing: Vehicles can now pass other vehicles using slower or oncoming lanes.
• Traffic indicator: Traffic lights can be customized to suit the simulation, and can also run in automatic mode. The TrafficSolver manages the advancement through the traffic light cycle as the simulation runs.
• Turning lanes: A vehicle that is not in the correct lane when approaching an intersection will reset its path, and recalculate based on its current lane and where the lane allows it to go.
• Pedestrian and Car decision making at intersections: Characters and vehicles can now replicate pedestrian crossing scenarios.
• Yield: Vehicles can now yield to oncoming traffic.

In addition, other traffic oriented features added to 5.7 that bring increased realism:

• User controlled U-Turns
• Clearance for three axes
• Road segment speed limit adherence
• Simplification of RoadNetworks
• Road network navigation optimization

Stability And Enhancements

Many other improvements have been done for release 5.7 of AI.implant, including:

• Scripting language simplification: LUA is now everywhere in AI.implant
• Units handled in the simulation with AI.implant are now visible with the AI.DE
• A better control on the environment data streaming flow
• Full support for 64 bit Windows and Linux

For more details, please read the AI.implant 5.7 release notes.

Version 5.6.2 - New Features

Turning

The position at which turning starts for RoadNetworks has been improved. The speed at which characters approach and travel around a curve has been improved with the introduction of the slowIntoTurns attribute. The movement is also more realistic with a wide range of vehicle settings.

A new attribute—maxCurveLength—has been added to the WayPoint Network. This defines the maximum distance between WayPoints in a curve, which improves speed adjustments in curves defined by many waypoints.

Enhancements

A number of defects have been fixed in this new release (see the release notes for more information)

Performance improvements have been added:

• Large, dense urban environment simulation has been optimized
• Large MetaConnection Networks have been improved
• Memory usage has been reduced for Streaming

Version 5.6 - New Features

Person Character

A person character represents humans in your AI environment. By default, a person is setup with dimension and dynamic values to generate realistic behaviours for a human. Through the AI.DE interface, users can modify the motionType and maxSpeed attributes so this person can be easily customized while remaining as realistic as possible.

Wheeled Object

A wheeled object represents ground wheeled vehicles in your AI environment. By default, a wheeled object is setup with dimensions and dynamics values to generate realistic behaviours for a ground wheeled vehicle. Through the AI.DE interface, users can still modify the motionType and maxSpeed attributes so this object can be easily customized while remaining as realistic as possible.

Wander behaviour re-invented

AI.implant users will now be able to create a more semantically rich wander behavior. By exposing more high level parameters the new Wander behaviour does more than the former WanderAround behaviour. It allows users to specify the environment in which the agent has to wander and within which environmental constraints it has to evolve.

A number of defects have been fixed in this new release
