TITLE: A cup of wine NAME: Fernando Gonzalez del Cueto COUNTRY: Mexico City EMAIL: fcueto@yahoo.com / fcueto@rice.edu WEBPAGE: http://www.owlnet.rice.edu/~fcueto TOPIC: Frozen Moment COPYRIGHT: I SUBMIT TO THE STANDARD RAYTRACING COMPETITION COPYRIGHT. JPGFILE: cupwine.jpg ZIPFILE: cupwine.zip RENDERER USED: Povray 3.5 TOOLS USED: Propietary C code, Corel PhotoPaint for brightness-contrast adjustments and cropping. RENDER TIME: approx 7 hours for the liquid simulation, approx 1.2 hours for the render. HARDWARE USED: Pentium-4 1.8Ghz IMAGE DESCRIPTION: I've always been fascinated by fluid dynamics, and still photographs of fluids in movement. That's why I thought it was a good idea to model a "A falling cup of wine". DESCRIPTION OF HOW THIS IMAGE WAS CREATED: I developed a program in which I simulate the behavior of liquids using a blob-component approach. It was coded in C and it may be available upon request. It is based in a inter-particle interaction dynamic system with a Adams-Bashford-Moulton predictor-corrector ODE solver. All the frames of the simulation are saved, but only one frame was selected for this competition. I spent many hours tweaking the C code to try to obtain more realistic effects. The image_map of the table was taken from the internet a long time ago, so I've already forgotten the author. I'm submitting everything a few minutes before the deadline, so, regrettably, I really didn't have more time to add more things. I wanted to add a few more things to the table. Also, I wanted to add focal blur, but I ran out of time. Also, I didn't have enough time to tidy up the code, so please try to overlook the mess.
