TITLE: "Steam crane of the 1860s" COUNTRY: Spain WEBPAGE: RENDERER USED: povray 3.1 TOOLS USED: Rhinoceros 1.0, Moray 3.1, Photoshop 4.0 RENDER TIME: 27 min HARDWARE USED: Pentium II 233 Mhz, 128 Mb IMAGE DESCRIPTION: This steam-crane was designed by J. Campbell Evans for use on board steam-vessels. The crane is worked by a single oscillating cylinder. The boiler is placed as close as possible to the crane and revolves with it, The boiler has lugs for attaching the tension-rods of the crane-arm. The bed-plate upon which the boiler and crane are placed is fixed to the foundation plate by a centre bolt. There are rollers running on the foundation plate, this plate is solidly embedded on timber laid on the deck of the vessel. There are two pairs of wheels and pinions for varying the speed of the chain-barrel. the crane can be moved round either way using the bevel-wheels. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: The crane was modelled in rhinoceros and then exported to moray to apply textures and to build the scene. Most of the pieces of the crane were made joining simple revolution surfaces and filleting edges. I used polar arrays of boxes to make the wheels and a extruded curve to make the bed-plate.
