https://kineticorp.com/heavy-truck-v-motorcycle-accident-reconstruction-case-study/
Strengths
Extensive 3D rendering
Multibody Optimization
non-linear spring/damper elements
specify target body rest positions
optimize multibody initial positions and velocities
can show both textured and DXF/Point
cloud vehicles simultaneously
2D or 3D vehicle geometry
Looming calculations
display angular rates for vehicle-vehicle
sightlines to calculate rates of approach
diagrams show angular rate and distance for each
sightline and shows rate at which angle changes
helps to determine detection threshold
individual sightline control
label sequences for greater readability
Advanced Monte Carlo
Collision Optimizer
exports and saves all run settings and results
cuts hours off search for best solution
multiple isometric views at once
multiple 3D cameras within one render for
multiple view and/or animated mirrors
LAS file support for 3D scans
Vehicle-to-vehicle
spring connections
attach springs and dampers directly between vehicles to simulate rope, chains, or other connections
camera-matching interface
Lighting
adjust hue/saturation/lightness,
brightness/contrast, invert colours
shadows, reflections, lighting
attach light sources to vehicles
solar calculator determines sun's
position for given location, date, time
combine multiple DirectX vehicles
super-resolution image enhancement
supports 3D scanner data
uses 360-degree panorama images
(e.g. Google Earth Streetview)
create 360-degree VR videos
Various support networks
free technical support (expert assistance)
training on demand (tailored to suit individual)
FAQ section
Courses (essential, expert, theory, skills & validation, coding)
live workshops (webinars)

Multibody Optimizer slow to run with
multiple multibody simulations
Simulation accuracy
impeded with the absence of hard data
reliant on hard data to establish exact
location points in simulation
electronic data (e.g. event data recorders)
physical evidence from scene
peer-reviewed literature
analysis of information gathered at scene
research and testing
principles of physics
open to interpretation of what
an individual was doing
dependent on reconstruction data to produce an
animation that can be admitted in court
matters based on factual evidence
requires expert testimony for
factual representation in court matters
can be jeopardized based on
an individual's assumptions
subject to involved person/s thoughts/actions
subject to interpretation by uninvolved persons
requires expert analysis to interpret what, why and how an accident happened, and if it could have been prevented
