class GeneralizedCentrifugalForceModelAgentParameters[source]#

Parameters required to create an Agent in the Generalized Centrifugal Force Model.

See the scientific publication for more details about this model https://arxiv.org/abs/1008.4297

Note

Instances of this type are copied when creating the agent, you can safely create one instance of this type and modify it between calls to add_agent

E.g.:

positions = [...] # List of initial agent positions
params = GeneralizedCentrifugalForceModelAgentParameters(speed=0.9) # all agents are slower
for p in positions:
    params.position = p
    sim.add_agent(params)

speed[source]#: Speed of the agent.

e0[source]#: Desired direction of the agent.

position[source]#: Position of the agent.

orientation[source]#: Orientation of the agent.

journey_id[source]#: Id of the journey the agent follows.

stage_id[source]#: Id of the stage the agent targets.

mass[source]#: Mass of the agent.

tau[source]#: Time constant that describes how fast the agent accelerates to its desired speed (v0).

v0[source]#: Maximum speed of the agent.

a_v[source]#: Stretch of the ellipsis semi-axis along the movement vector.

a_min[source]#: Minimum length of the ellipsis semi-axis along the movement vector.

b_min[source]#: Minimum length of the ellipsis semi-axis orthogonal to the movement vector.

b_max[source]#: Maximum length of the ellipsis semi-axis orthogonal to the movement vector.
