Strengths
Integrates
Google Earth
Imports regional data
Imports aerials to scale automatically
Builds terrain surface mesh
Converts point cloud to
3D terrain surface mesh
Vehicle capability to drive onto surface mesh
Simulation terrain directly from scene measurements
Points in any orientation draped by surface mesh
Mesh created directly from point cloud of any structures, trees or other objects
supports total stations and RTK GPS devices
supports third party terrain meshes
Imports point clouds
directly into simulation
Ray tracing effects -
realistic visual aids
Smart HUD allows vehicle speed and distance data to be displayed anywhere in playback window; or move with vehicles
Create animated motion
sequences with Path
Animation tool
doesn't need to use simulation engine to control vehicle motion
automatically interpolates data when key positions and orientations along the vehicle trajectories are specified
animated and non-animated objects can interact within scene
Adjustable sun position and volumetric lighting
Simulations
produced rapidly
Easy Surface Builder quick and intuitive
rigid body dynamics in physic
engine permits fast workload
imports and scales aerial images quickly
multi body collision
physics model
motorcycle, bike, pedestrian impact
simulations created fast with immediate results
tractor-trailer simulations
fast
ability to fine tune tractor-trailer system
studies dynamic load shifting
instantly see results of changing
simulation inputs in real time
unique fast control icons gives ability
to control steering and braking
Support and compatibility
with variety of equipment
orthomosaics, UAVs
3D laser scanning
RTK GPS
total stations
import 3D models of objects
Supports Ultra HD animation videos and diagrams
Supports 360 degree videos and virtual reality capabilities
Builds complex roadways
fully customisable in 3D
adds custom grades and crowns to road surfaces
Orthographic views
camera can switch perspective to orthographic view to perfect road design and create visual aids
Vehicle customisation
imports 3D scan meshes
supports third party vehicle meshes
dxf and 3ds formats
modify inertial properties and wheel positions
add custom colour patterns and unique vehicle features eg. sirens, bumpers
Economic value
Free training content online
no annual maintenance or software update fees
Free trial downloads
Weaknesses
Expensive
$6200
Reliant on hard data retrieval
Accuracy can be compromised
limited or no hard data
creates speculation of event/accident
can be misleading, misinterpreted
soft data can be applied (e.g. witness statements, perspective based on outcome desired)
needs credible professional to iterate where soft/hard data has been applied (e.g. for court room purposes)
dynamics can be misrepresented
open to bias when developed
graphics can be a mix of soft and hard data
data can be incorrectly inserted by user (human error)
not always able to re-create an
event/accident with 100% accuracy
