Definition |
"To create a computer rendered 3d image, a computer calculates path of light around a model, which has specific textures, patterns, and translucency, to illuminate the model as the human eye could see it." Computer Generated Images are everywhere in today's society, including
medicine, movies, agronomy, architecture, military , games... The true power of 3D modeling is that the designer has complete control over everything the eye would see: perspective, lighting, scale, point of view, and the 3D models themselves. Controlling every aspect of the 3D models makes computer rendered images useful for:

Medical Graphics |
Medical graphic artists produce computer generated scientific graphics for various purposes, including surgery visualization , experimentation, interactive instalations, slide presentations, journal and textbook publications... Installations:

Movies |
"With virtual reality, the computer generated images became interactive or, more precisely, remained interactive, revealing the strength of their initial affinity with the cinema. True, the calculations and logical models which are the basis of such images set them outside the tradition of photography. But in order to appear, to find a form of realization, they soon turned to the media of film and video. In this sense, they belong to the tradition of film animation. On the one hand, the work done by a graphics system has analogies with drawing techniques and can be seen as a form of animated cartoon which has acquired a greater autonomy and greater coherence with its medium. On the other, the modeling and simulation of spaces, forms and light effects, behavioral animation, real time animation and all these state-of-the-art techniques, with their propensities towards photographic realism, were bound to lead automat images which can be almost seamlessly hybridized with shot footage." Jean-Louis Boissier.

Facial Animation |
Facial animation is now attracting more attention than ever. Imaginative applications of animated graphical faces are found in sophistical human-computer interfaces, interactive games, VR telepresence experiences, and as always, in a broad variety of production animation. Graphics technologies underlying facial animation now run the gamut from key framing to image morphing, video tracking, geometric and physical modeling, and behavioral animation. Supporting technologies include speech synthesis and artificial intelligence.

Plant Evolution |
"The main objectives for the use of computer generated images in Plant evolution is to identify general plant organization and functioning principles, to evaluate the variability of plant architecture with a view to breeding or genetic improvement, to explain and model integrated plant and plant stand functioning with a view to quantitative and qualitative production forecasting. To represent landscapes and their evolution with a view to rural and urban land development, to characterize the geometric structure of biological entities with a view to diagnosis."(CIRAD) Installation: Christa Sommerer and Laurent Mignonneau

Architecture |
Virtual Architecture and more recently Transarchitecture, introduced
by Marcos Novak are a direct result of the unlimited possibilities that
computer generated images provide.

Military |
"The gulf war brought home the profound changes which are affecting the world of images today. If this war confirmed the importance of television image, the effects of which remain essentially ideological or psychological, it also revealed the terrifying efficiency of the virtual image. Invisible to the eye of the public, these images had their own logic, a logic not of communication but of commutation. The images allowed aircraft or guided missiles to hit their targets with tremendous precision, by means of calculators which, at each instant of the flight, compared the image of the terrain flown over by radar or infrared scanning to the virtual map system loaded in their memory, containing all the information needed for the mission."(Edmond Couchot) Installation: World Skin, by Maurice Benayoun

Games |
The evolution of computer generated images designed for computer games, or other stations (Playstation, Nintendo...) has rapidly evolved during the last twenty years. Images look more realistical and the game and movie industry are becoming closely related.
