The 350 gallons per minute (gpm) pump is a mobile, diesel engine driven, fluid pumping assembly. It is used to transfer fuel and water and can be staged inline with other pumps to span over long distances. This model was developed for the operation and maintenance courseware for the US Army. It was created in 3D Studio Max, rendered with Mental Ray, and composited in Photoshop. It was textured using a combination of photo references and procedural materials. The modeling, texturing, lighting, and compositing were created in whole by Tim Gragg.
