SEAL Tradeshow Presentation

YouTube Videos

   


 

Several levels of scientific visualization presentation are available to meet customer needs. Shown above are 3-D vehicles on a basic 2-D road drawing. An accurate simulation model of motion and object perspective does not require detailed color and texture rendering. An  accident sequence may be shown in wire frame only. These presentations employ the same physics as fully rendered graphics.

 

Another solution to 3-D scientific visualization, including 3-D vehicles, such as passenger cars, trucks, semi-tractor trailers, vegetation, road and road contours, may be generated using ARAS 360®. These physics-based models include variables such as vehicle speed, weight, size, tires, road surface, driver steering, and braking input, as well as hundreds of other data input factors.

 

Fully rendered 3-D environments including extensive texture mapping of actual scenery and complex 3-D objects result in a high degree of visual realism. Scientific visualizations of an event based upon input from a combination of witness testimony and evidence using physics and laws of motion to determine time and distance relationships between objects to define motion.

    3-D Simulation

SEAL graphics are created at the SEAL offices under the supervision of the project engineer. Color or texture can be simple or complex.

 
A scaled 3-D oil well drilling rig was created to visualize a derrick collapse. Many thousands of movable sub-objects were used to create the velocity curve necessary to depict the entire collapse. Because the rig was created in 3-D, it may be viewed from many angles during the collapse.
 

Above an example of the beginning stages of visualizing parts of a snowmobile. Steering movement of handlebars and skis along with  track movement adds to realism. Mountain terrain with trees and snow are used to create the necessary realism to depict the snowmobile accident.
