Macintosh sur le bureau
 

This picture created in 2005 is a synthetic (or "virtual") image I made on my Macintosh using Persistence Of Vision (POV) Ray-tracing. The image is built geometrically, using so-called "Constructive Spatial Geometry".

All the objects are created and assembled by geometrical programming using POV. A virtual camera and virtual light sources are then set, and the picture is created ("rendered") by "ray tracing". By moving the camera around, you can take any number of 3D pictures of the same scene (see the house project), including panoramic views. You can also make animated GIFs (see the moving train). Textures and patterns are programmed with POV. I am particularly proud of my "Orient Express" section.

The Mac fans will notice that the iMac G4 is a little simplified. The screen itself is a dump from my own Mac.

Several objects here and in my House project were adapted from files created by others. Here the corresponding acknowledgements. The splendid yellow flying boat was created by Kurt Bangert. It is a very faithful reproduction of the Boeing 314 "Yankee Clipper" operated by Pan American between 1939 and 1951. For interest, here are the specifications and a photograph of the original big plane. With POV, I made 99 different pictures of the plane flying around the island, and converted it to an animated GIF*.

The Apple keyboard with its 110 keys took me five days to create...


The Orient Express

This luxury train was in service between 1883 and 1973 on different routes (see below), the main one being Paris-Istanbul. It was essentially operated by the "Compagnie Internationale des Wagons-Lits et des Grands Express Européens (CIWL)". The locomotive was a steam engine. In the years 1910-1960, it was mostly the legendary Pacific 231. See a recent very detailed and well illustrated historical review in French, which I have used to design the CIWL carriages and the Pacific 231.

Le château de Moulinsart (Marlinspike Hall)

Marlinspike Hall is a manor bought by Professor Calculus (Tournesol) on behalf of Captain Haddock in Hergé’s The Secret of the Unicorn. Hergé used the castle of Cheverny as a model, removed both big lateral parts of the castle, but kept most of the details of the center part. I reconstructed Moulinsart with POV, using Hergé's latest variations.

The Oxford college

I started from photographs of the All Souls college found in the internet.

The Italian villa

I created the Italian villa based on a painting by Francesco Granacci. See on the right my version and the original, viewed under the same angle. Unfortunately, it is impossible to describe convincingly human beings with pure geometry, and vegetation is also difficult to model, as you can see from the tree, and takes a long time to render. On the right: a wide angle view of the villa. I borrowed the statue from an unknown expert.

Bureau virtuel de François

In this other picture, 4 items are imported in form of "Image Maps": these are the Tintin picture on the wall, the photo on the desk, the apple logo on the pencil holder, and the "Happy New Year" text on the desk. The other items are all constructed geometrically.

I have borrowed some of the wooden textures from Dan Farmer and Paul Novak. These are supplied together with the (free of charge) ray tracing software of POV.

I created all the other objects: the column, the table, the paperweight, the pencil holder and the picture frames, and assembled them to this picture. It took me about three days (in 1999)...

On my MacBook Pro (2018) the desk picture is rendered in 9 seconds. On the previous MacBook (2011), it took 38 s, on my Macintosh G4 with biprocessor at 1 GHz (2002), it took 3 minutes 17 seconds in a 1024 x 768 pixel size. On my Mac 8500 (1998), it took one to two hours, and on my old Mac IIci (1993), rendering the same image could take as long as a full day... The desk image is a compressed jpeg of 1024 x 768 pixels. The plant and the tree are based on a file by Jean-Laurent Pradel (1998). There are 21 parameters to play with and change the style of the tree, its leaves, and its branches. You may see six examples in this page with different settings. The result looks somewhat artificial, but the image renders quite fast, because the algorithm used to create it is very compact, which does not mean it is simple.


* Note: Some of the images are animated GIFs. They have been designed to loop only a few times (typically 3 to 8 times). However, this doesn't always work, and sometimes the image loops forever. Additionnally, you may have to re-load the page.
