Engineering Animation

Laurence R. Penn, 3D Modeler and Animations Expert ::::

When it comes to creating compelling, scientifically-based Computer-Generated Images (CGI), V-Ray from ChaosGroup is now the render engine of choice utilized by DJS Associates’ 3D Engineering Animation Department. V-Ray is a physics based texturing and rendering platform used by many top studios around the world. In fact, V-Ray received an award at the 2017 Academy Awards from the Academy’s Scientific and Technical Awards Committee for its role in bringing realistic CGI to the big screen.

Recreating Vehicle Movements: Update from our Engineering Animation Department


1 Engineering Animation Vehicle Path

Hugh Borbidge, BSME, Director of Engineering Animations ::::

There are many ways to re-create vehicle movement in a 3D computer environment. Some methods are better than others. We will talk about 3 different methods; simple, rigged, and physics based.

Engineering Animation Vehicle PathThe simple method is the easiest and fastest method as the name implies. The vehicle is treated as one object. The chassis and wheels do not move independent of each other. They all move as a unit. In the image above, the red lines represent the tire paths. You can see that the front and rear tires follow the same path even as the vehicle makes a turn. This is not scientifically accurate but can sometimes be useful for a “down and dirty” review for things like basic spatial relationships.

Item 101- Accurately Moving a Vehicle on the Computer Screen

3D engineers that do forensic work often times feel a little jealous when we watch a Pixar movie. In Pixar movies vehicles tend to move in such an artistic way. They are seen bopping to music, bending around corners, and even talking. Many times the creative teams behind these movies ignore the laws of physics. But that’s ok, they don’t have to. Accurate engineering animations, on the other hand, do have to abide by the laws of physics. Engineering animations can be (and typically are) highly scrutinized and the slightest inaccuracy can render them such that they are not accepted by the courts.
