Computer graphics, modelling and 3D Animation

Computer graphics

A CSG computer graphics specialist fulfils many roles: illustrator, designer, layout artist, as well as everything to do with manipulating images: from cleaning up photos to restoration, as well as improving colour contrast, cropping (recentring images), etc.  In addition, computer graphics can be applied to video, which may require the specialist to work in two or three dimensions (2D, 3D), overlaying text, graphical or animation elements to add more interest.

The computer graphics specialist must also be a multimedia expert, in order to produce the interactive CD-ROM produced to record each launch campaign.  This requires both programming and the coordination of text, graphics and animation production together with the creation of (or respect for) a graphic charter.

Depending on its ultimate purpose, each photo will be treated in a different way by the computer graphics specialists.  For the inspection photos, which are required for Quality assurance, there is minimal retouching, in order to leave any significant points intact.  On the other hand, for a media photo like those appearing in Latitude 5, the specialist manipulates the image far more, cleaning it up to improve its clarity and colour, cropping as necessary, and erasing unwanted details which may detract from its beauty or relevance.  The specialist is also called upon for other computer graphics work such as for the website and CNES/CSG computer desktop designs.

Modelling and 3D Animation

Although 3D images are created entirely by computer, they still require the involvement of the specialists for complementary modelling and 3D animation work.

Modelling, to mould forms and create volume for a defined object such as a satellite, using a technical drawing or a flat image as a starting point.

3D Animation, because skills associated with video are required, such as staging, lighting and scene direction, just like in the movies.

The three applications of 3D at CSG

-  for an Ariane launch: producing computer-generated scenes in order to broadcast and track the key stages of the flight sequence, in real time, on the image wall in the Jupiter building.

-  producing the campaign film and responding to various requests from the communications department: 2D or 3D overlays such as labelling, addition of an animated logo or creation of credit titles.

-  3D is also used to produce 2D images, as it can be a more effective way of creating volume or 2D elements that are difficult to produce otherwise, depending on the perspective.

Potential for developing the activity and the associated creative skills

The CNES/CSG Optical/video team also fulfils orders from the Space Museum, depending on their requirements for new exhibitions.  In particular, it created one of the museum's regular features: the jeu de l'oie (based on a traditional French board game).  The computer graphics designers find creation and 3D work most rewarding, as it allows them to put their innovative ideas to good use on a regular basis, improving existing work while adding their own personal touch.  An example is the photo posters which were on display at the Salon du Tourisme trade show and during the Heritage Days.  Superb pictures from the service's image bank have also been used to put together a catalogue of technical photos given added artistic value by the way they were framed or shot.  This gives a completely different perspective on space activities and their associated skills.  The resulting creations stand out for their sensitivity and individual inspiration.
