Minutes of the first Morse International Workshop (June 2013)

Discussion about discrete event system

+ What is our needs ?

• - primitive events:
  • - x entering in certain area - picking obj / releasing

    - collision / touching -> material

    • -> whole object

  - client subscribes to "event feed" - hierarchy of events - it would be nice to have by-'agent' event (agent perspective awereness) - specifying region of interest (both in builder and blender)
  • - sensor, actuator attached to a mesh ?

+ API proposal ?

• - pymorse level
  • - allow a way to retrieve all kind of events

    - high-level interface to describe event -> reaction (see slide)

  -service level
  • - load meshes + primitives - details needed from the simulation ?
  - builder level
  • - separate dynamic controller from the builder script ? - component level:
    • add_event() to register new events from a component

Faster than realtime simulation

Still need to better understand how time works in Blender / Morse

- proposed mode by Charles:

• - "best-effort" real-time:
  • - drop frame if neeed
  - "simulated time":
  • - don't drop anything, but move the simulation 'clock' accordingly

• - hacking at the btDynamicsWorld::stepSimulation() level - hacking the blender clock

  - checking for the 'TimeScale' parameter - http://www.blender.org/documentation/blender_python_api_2_67_1/bpy.types.SceneGameData.html#bpy.types.SceneGameData.use_frame_rate

Anyway, we need to hack in Blender

Humans / need human

Different needs:

• - avatar that can be controlled by user - simpler models that we can spawn around
  • - with less level of freedoms - with several animations

- Track multiples human with kinect input - Replay gestures from registered inputs (motion capture for exemple).

- investigate detour | recast + new interface to define path to navigate

- Code need cleanup
