Terragen...
Aujourd'hui ce mot est devenu synonyme de logiciel de création de
paysages, de "rendering" selon sa dénomination anglo-saxonne.

Photorealistic landscapes
Terragen....
Today this term is became a byword to describe scenery and rendering
software.
|
Et
de fait, Terragen est l'un des premiers programmes à explorer ce
domaine d'une manière aussi complète et pratiquement sans
limitations.
J'ai
le plaisir de vous présenter ci-dessous mes réalisations
personnelles. Consultez également les galeries Astronomy,

et Astronauts,

And
de facto, Terragen is one of the first application to explore this
field in a so complete way and practically without limitations. It is a remarquable tool quite easy to
use that permits to each of us to create photorealistic landscapes.
I
have the pleasure to present you below my personal creations. See also

"Imagination
is more important than knowledge"

Our Blue Planet Earth
is the cradle of the Human kind. Our blue planet is also the only
planet in the Universe where we know that an intelligent life has successfully
developed. In this context it is a very seldom gift from mother
Nature that we have to preserve. In 4.5 billion years, the
biosphere has become luxuriant and displays an amazing variety of
forms and colors that sometimes let us dreamy. There are these
feelings that I have tried to reproduce in the next series of
renderings. |

Mission
to Mars
Mars
is a planet as small as the Moon. Like it, it is dying, riddled with
impacts and fractures. Its surface is cold, arid, sanded up, and
very dry. Due to its low mass, Mars was not able to retain its atmosphere
that partially escaped into space. The remain has become too light
and does no more - if ever it did - allow the development of life.
Worse, its surface receives extreme UV radiations, heavy cosmic
rays, and its dust is maybe toxic, allergenic and cancerigen.
For short,
despite appaerances Mars is inhospitable. Today the mean surface
temperature is close to -60°C and the atmosphere is mainly
composed of carbon dioxid. In early morning, white frost and mist invade craters and all
reliefs sheltered from the wind. Here and there, close to the
polar caps, after the carbon dioxid sublimated into the
atmosphere, the bottom of craters covers with water ice as shown
Mars Express space probe in 2005. Everywhere the underground is
made of permafrost and ice caps cover permanently one or both polar
regions.
But Mars can revive thanks to a
terraforming process, transforming the currently sterile planet
into a fertile and breathable world. As Mars is a small planet, the process must
be intensive and continue. If we can rewarm its atmosphere in
pouring into greenhouse effect gases and simutaneously rewarm its
surface in exploding some large volcanoes and using mirrors to
rewarm the soil, the permafrost could liquefy, raise to the
surface, and begin invading plateaus and valleys. At the begin the
cristal-clear water will be a few centimeters deep only but
after some hundred years, true lakes and maybe even an open sea
could form.. At the same time, if we inject huge amounts of
photosynthetic bacteria in the atmosphere, oxygen could be
produced. At the end, moisture will increase in the
atmosphere creating fracto-stratus and high clouds. The sky color
today pink to orangeous due to dust in suspension will tend to
the blue creating amazing landscapes. These are some of these
possible worlds, past, current or future that I present you below,
Mars the Red, Mars the Blue. |

Mission to Titan
Larger
than Mercury and Pluto, Titan is the largest satellite of Saturn
and of the solar system. It was visited in June 2004 by
Cassini-Huygens space probe that revealed under its thick
orange atmosphere a strange and unexpected world.
Its surface shows bright mountains and dark
areas as well as what looks like to drained delta, draining
channels that maybe carried out methan or ethan millions years
ago. Closeups revealed plains covered with icy rocks.
In
2005, thanks to a sunny spell in Titan atmosphere, a well delimited
dark surface was discovered close to the
South Pole. Remain to know if this surface is liquid or solid. In the
event of this feature is a lake of hydrocarbon, Titan should be
the first satellite in the solar system to display a liquid
surface.
Today
Titan is too cold (-179°C at the surface) to allow the
development of life but who knows, far under the surface, some
extremophiles could maybe survive. Added to the presence of organic material, aerosols, a little
underground heat and maybe icy water in depths, Titan remains a
favorite destination for future space missions to know until where the life could
go on an extraterrestrial world. |

Terragen
2 ajoute de la végétation plus réaliste et une structure
nuageuse plus complexe ainsi que de nouveaux outils comme un
éditeur de relief plus puissant, l'effet des réflexions des lentilles, de
nouveaux imports, etc.
Afin
de profiter de toutes les options de lissage et obtenir la
meilleure qualité d'image, achetez la
version enregistrée de Terragen. Non seulement de cette
manière vous encouragez Matt P.Fairclough à améliorer son
produit, mais cette version vous permet également de créer des
images de plus grandes dimensions.
Côté
matériel un ordinateur cadencé à 500 MHz et disposant de 196 MB RAM
(Pentium III) suffit pour utiliser Terragen v0.9.43 bien que
cette configuration ralentisse le traitement.
TG2
ayant été totalement reprogrammé, cette version exige un
minimum de 1 GB RAM mais sera plus à l'aise si elle dispose d'un
système performant et de beaucoup de
mémoire (CPU de 3 GHz, 4 GB RAM et 256 MB VRAM).
Dans
les deux cas Terragen peut fortement solliciter votre
ordinateur, principalement le CPU lorsque vous créez des
paysages complexes avec des ombres portées, de l'eau, etc. Voyez
à ce propos cet article
rédigé en anglais. Notons
que depuis fin 2006 plus aucun développement n'est assuré pour
la version Classique 0.9.43. Seule la version TG2 connaît de nouveaux
développement. Elle est déclinée en trois produits y compris
une version gratuite. Terragen
Classic 0.9.43 tourne sur Mac OS 9, X et toutes le plates-formes
Windows 32 ou 64 bits. TG2
tourne sur Mac OS X et les plates-formes Windows XP et
supérieures de 32 ou 64 bits. |
Terragen
2 adds more realistic vegetation and a more complex clouds texture as well
as new tools like a more powerful relief editor, a lens flare
effect, new imports, etc.
In
order to benefit of all anti-aliasing options and get the best
image quality, buy the registered version of
Terragen. Not only in this way you encourage Matt P.Fairclough
to improve its product but this version allows you to create larger
images too. Hardware
side, a computer running at 500 MHz and using 196 MB RAM
(Pentium III) is
sufficient to use Terragen Classic 0.9.43, although this configuration
will slow down the processing. TG2
having been reprogrammed from scratch, this version requires 1
GB MB RAM minimum but will be more at ease using a performing
system and much memory (3 GHz CPU, 4 GB RAM
and 256 MB VRAM). In
both cases, Terragen can hardly
appeals your computer, mainly the CPU when you create complex
landscapes with shadows, water, etc. See this article
that I wrote about this subject. Note
that since end 2006 there is no new development for the Classic version
0.9.43. Only TG2 know new developments. It is declined
in 3 products including a free version. Terragen
Classic 0.9.43 runs on all Mac OS 9, X and all Windows 32 or
64-bits platforms. TG2
runs on all Mac OS X and on Windows XP 32 or 64-bits platforms
and higher. |

Vous
pouvez obtenir la dernière version de Terragen pour Windows ou
MacOS sur le site officiel de Planetside. Actuellement,
ses principaux concurrents sont MojoWorld
et
Vue d'esprit, tout deux sous licence et beaucoup moins intuitifs. La NASA propose également
un outil de recherche très puissant et très gourmant en ressources appelé WorldWind.
Il mérite votre attention. Si vous désirez créer des objets,
des animaux, des personnages ou de la végétation, Bryce
est un excellent produit parmi beaucoup d'autres logiciels de
rendu 3D. Complété par Photoshop et des photographies ou des
dessins numérisés, vous avez à votre disposition
tous les outils qu'il faut pour devenir illustrateur ! |
You can get the
last Terragen release for Windows or MacOS on the official website
of Planetside.
Currently
its main competitors are MojoWorld
and
Vue d'esprit, both under license and much less intuitive. NASA
also provides a powerful and resources hungrier search tool called
WorldWind.
It deserves your attention.
If you want to create objects,
animals, people or vegetation, Bryce
is an excellent product among many other 3D rendering software. Completed with Photoshop and digitalized
pictures or drawings, you have at your disposal all tools you need to become
illustrator ! |
