Technical Animations - Using CGI for Failure Analysis Reporting

By Tim McGarvey


Engineering animations use CGI, computer generated imagery, to test, build, manufacture and market complex new products, or processes. Complex products and processes can be explained using engineering animations to re-create disasters, industrial accidents, airline crashes, etc. for television and news programming.

Engineering animations can also be used to design and build complex structures in 3D or to investigate mechanical engineering failures for use in litigation involving industrial accidents. The creation of any kind of mechanical animations or technical animations in CGI requires the use of mathematical, logical sequences to program, which allows products or processes to be built exactly to scale. This allows the artist to create realistic elements using the exact specifications scaled to fit a small screen. This can eliminate errors in design, and reduce costs later on in the prototyping stage. It also allows the 3D artist to model and build processes that cannot be seen by the naked eye, such as medical devices inside the body, or processes happening on a molecular scale.

These animations are often used in television or video production, especially information heavy stories that need to be explained quickly to viewers, such as information related to mechanical failures that cause disasters or accidents. Engineering failure analysis can also be improved with the use of a detailed 3D animation. Engineering animations are create using special software, which builds exact replicas of structures or machines and then can be used to look at complex issues such as load distribution or stress evaluations.

While there is wide spread use of the term, engineering animations can be categorized into several general areas: Product animation, conceptual animation, process animations, training animations, medical devices, and architectural and construction. Animations in the conceptual category includes the testing of product design, and designing 3D mock ups of the product to show investors or research and development executives. The costs of developing and manufacturing can be significantly reduced if errors in design are discovered in the 3D development and if everyone involved in the process understands the product in detail.

These types of animations can also be used when marketing a new product, explaining product benefits quickly and clearly and by helping to create more exciting, visual sales presentations. It has been shown that visual aids such as 3D animations of complex products or information increases viewer retention, which is a plus when producing video productions, television series, training materials or when presenting at trial.
