EMAIL: bergerj@iname.com NAME: Jerome BERGER TOPIC: Contrast COPYRIGHT: I SUBMIT TO THE STANDARD RAYTRACING COMPETITION COPYRIGHT. TITLE: The Workshop COUNTRY: France WEBPAGE: http://www.enst.fr/~jberger RENDERER USED: mPov 0.6.2 (http://www.enst.fr/~jberger/mpov/mpov.html) TOOLS USED: paintshop pro, the gimp, moonlight atelier, spilin editor, gcc RENDER TIME: parse: 6s, photons: 2m 35s, render: 8h 10m 47s HARDWARE USED: P-II 333MHz, 64Mo RAM, Linux VIEWING RECOMENDATIONS: Dark images show big variations from a computer to the next. According to the gamma test from www.povray.org, my computer has a gamma of about 2.4. This makes the details of the cupboard at the back of the room barely visible. IMAGE DESCRIPTION: What would the great painters like Leonardo da Vinci have done with computers and 3D software? This picture shows the workshop of one such painter, to whom a computer has just been given... DESCRIPTION OF HOW THIS IMAGE WAS CREATED: The first thing that came to my mind when thinking of art and contrast was the painting (and photo) style called "clair-obscur" in french (word for word, it would translate as "light-dark"). From there came the two ideas: to do a picture like that (which would allow me to work on lights in my pics) and to show another contrast: that between the tools used by those who invented this style and the tools we use for the IRTC. Nearly everything was hand-coded. The only exceptions are the hair of the round paintbrush (modelled in Moonlight Atelier) and the bottle (Spilin Editor) and those mostly because I needed an excuse to try these softs. The piece of cloth draped over the computer was generated by a small program I wrote in C++ and which I hope to develop into a full-fledged cloth cimulator later. I first wrote a scene file in which I placed colored boxes and played around with light sources and radiosity to get the effect I wanted. Then I modelled each object individually in separate include files and replaced the boxes with those. The picture of Mona Lisa was found on the web, the sphere-on-a-checkered-plane picture was made with pov (including focal blur, reflection blur...) and the signature was made in paintshop-pro (I have yet to configure my linux box to access TrueType fonts) and adjusted in the gimp. Isoblobs are a great feature too often overlooked. Even if their syntax could be better, they are a great modelling tool. All in all, I'm rather surprised that the picture didn't render more slowly: it uses radiosity, photons, media (both scattering and emission method 2), isolobs and isosurfaces... Most textures were taken from the povray.org newsgroups and then tweaked to suit my needs. I'd like to thank all the people who posted them so that others could learn.
