Cerro Gordo Scenario
3D animation of fire based on Farsite time of arrival estimates. Approximate smoke is added to indicate wind direction and reduced visibility during evacuation
Quicktime animation (5 mb)
.avi animation (37mb)
Green area of image indicates first hour of burn based on Farsite simulation. Red indicates the second hour of burn.

Animations from Fire and Traffic Models
Flyover from Sandias to Mt Baldy. Rendered in Blender. Elevation mesh was tranformed based on DEM data.
Level 0 models for Intersection Study
Currently only random routing
One 2x2
Cellular Automata Fire (low resolution)
Level 0 fire model
Simple modification to Netlogo fire model
No slope, no wind and uniform distribution of fuel with 60% density.
Flyover of Santa Fe
Rendered in Blender. Elevation is a displacement map from a DEM JPEG image.
This is contrast to the direct transformation fo the mesh based on
the elevation data done in the movie above. A simple 4-color texture
is on the terrain and a road texture mapwith an alpha chanel was included.
Test render using Netlogo CA Fire and a homogeneous fuel model as a texture map
Test render using CA Fire implemented in Blender
Test render of particle-based flame
Test render with simple CA Fire implemented in Blender
Corrected DEM. Tops of mountains are no longer mesas
Perfunctory graph showing power law-like distribution of length road segments in Santa Fe area.
