Delivery 2: Radiometry Improvements
Finished work on the new “simple
”
radiometry
solver that drives high fidelity radiometry very quickly
Resolved issues with specular lobe falloff modeling that created artifacts in Delivery 1ABI Delivery 2

Delivery 2: CityEngine Integration
driveway/access nodes for lot design and SUMO
integrated sidewalks, road verges, crosswalks, driveways, curbs, and shoulders
correct lanes
for OSM and
SUMO
integration
Resolved issues with OSM/SUMO/
CityEngine
lane integration
Added road context modeling in
CityEngine
, adding parking/breakdown lanes, gutters, verges, driveways, curbs and sidewalks
Driveways and shoulder space will act as nodes for SUMO integration using edge ID and position information extracted from
CityEngine
Regional variation still limited by buggy attribute mapping in
CityEngine
-- attempting to switch to scripting

Delivery 2: SUMO
Meeting with MITRE on Monday to learn more about SUMO usageDelivery has a trip/route for an 8 vehicle caravan with a midway split (2 vehicles leave caravan)
Caravan mechanics (lead/trailing car and “following” behavior) are hacked in using lane restrictionsHad to reduce number of cars to 1000Need better vehicle articulation/placementIntent is to link trip start/end locations to driveway nodes and add non-networked simulation data for parking lot motion

Delivery 2: Added DIRSIG Tools
Added addition population distribution tools allowing arbitrary discrete distributions of object geometry and sub-object material variantsAlso added a simple (static) temporal variant tool that allows objects to be turned on/off on a daily time schedule (e.g. on between 2 and 3pm)

Scene Fidelity Improvement: • Texture improvements for buildings and roads• Lot design and better building models
• Linking node data to lot design• Road signage/lights and general clutter• Additional attributed vehicle models•
Additional tree species and distributions Dynamic Scene Content:• More sophisticated traffic modeling• Significant increase in population size• Un-animated node start/stops
