TITLE: Shallow Water Channel, Ebb Tide NAME: Greg M. Johnson COUNTRY: USA EMAIL: gregj56590@aol.com WEBPAGE: http://members.xoom.com/gregjohn/animation.html TOPIC: Stills COPYRIGHT: I SUBMIT TO THE STANDARD RAYTRACING COMPETITION COPYRIGHT. RENDERER USED: Megapov 0.5a TOOLS USED: CorelDream3D, Win3D,sPatch RENDER TIME: 27 h 31 m HARDWARE USED: Aptiva PII 450 MHz IMAGE DESCRIPTION: Image inspired by the Kursk tragedy and recent news about bringing up the Hunley from the sea floor. The sadness of these events had me singing Thomas Dolby's "One of our Submarines." A line from the song, I believe is "shallow water channel ebb tide." I wanted to make an undersea image of someone discovering a sub on the sea floor. Areas in need of improvement: 1) better explanation as to why a spotlight focused on the sub. (Original vision was to have a scuba diver or rescue sub but ran out of time). 2) emitting media to make the sea colored instead of black. 3) better texture for normals on sub. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: I got a submarine model off of the CorelDream3D CD. I exported it out to DXF and then used Win3D to conert to POV. Everything else is my creation. 1) Sea floor is an isosurface. 2) Shark and fish are sPatch-created bicubic patches. 3) "Sea" is actually two media, one scattering and one absorbing. If I had more time to tinker, I should have combined these two into one media statement and added another, emitting (or blue scattering?), to "color" the water.
