Wärtsilä – 2-Stroke Engine

Wärtsilä – 2-Stroke Engine

  • Client: WÄRTSILÄ
  • Production Company: ALSO STARRING

Troll produced another corporate video for Wärtsilä, a leading power source manufacturer. The 2-stroke engine is their new, highly efficient dual-fuel motor designed for marine use.

My job was to create the ocean for the two shots that required it, as well as doing some rendering and compositing work. This was also the first time I used RealFlow in a commercial production, creating the interaction of the water with the ships.


The ocean in both shots was created by using vector displacement maps generated with Houdini Ocean Toolkit and rendered in two layers to give it some variation. Not the ideal method but worked well enough for this purpose.

 


While the simulated interaction was working fine it definitely needed some comp magic. The foamy wake seen here is actually a top-down render of a simulation extended and composited over the image in Nuke. Faster, easier and looks really nice.
