HIGHVOLT.JPG By:- John Hooper (aka Stomp) Date:- 29-jun-1995 Rendering Time:- 32.5 Hours on a Pentium 90 Software used:- Povray 2.2 PovSB 0.99f Spark (my program) Description:- Electric is an image of a High Voltage Test Laboratory. The central object is a Cockcroft Walton Voltage multiplier (Sometimes used as the first stage of a particle accelerator). Ever since I was a kid I've had a fascination with High Voltage, this carried through to a degree in Electrical Engineering. The first time I saw a Cockcroft-Walton Multipier was in the London Science Museum in 1985. Also showing at the museum was a travelling exhibition of fractals by H. Peitgen and D.Saupe. Both of these people later produced a book called "The Science of Fractal Images" from which I derived a simple program for creating the sparks in the image. Basically the sparks are generated using psuedo 3-D Brownian motion to produce a string of cylinders that "looks like" lightning. The spark program generates a Pov include file and/or a PovSB (Pov Scene Builder) file. Once the spark is imported into PovSB it is simple matter to move it to an appropriate position in the the wire frame model of the scene. Addendum:- This image is an update of electric.jpg, I decided to personalise the image after discussions with a friend, Adrian Witham. My image was imported using a video frame grabber and then placed in the scene using a gif map. It helps to clarify the size and perspective of the scene. Credits:- I would like to thank the Pov team for writing a truly flexible and powerful raytracer and Jeff Hauswirth (jhauswir@carbon.denver.colorado.edu) author of PoVSB (Windows PoV Modeler) which made my modelling job orders of magnitude easier.
