One of the most asked questions on Google
What is CGI? ... Computer Generated Image ‘CGI’ are images created within 3D software with no need for photographic involvement. These software solutions have been used for many years as architectural visual and design tools and within the special effects industry for film and television.
More recently with software improvements and the introduction of ever faster computer processes it is now possible create true photo-realistic images using these CGI technologies. These software packages are no different to any other creative tool; the quality of the results depends on the creative skills of the users, just as you expect with a traditional photographic camera or design software.
CGI offers several advantages over photography. Space is no longer an issue, a set can be any size or design so standard restrictions like studio space/height aren’t an issue. Repeatability is also a major benefit. Because everything is in a virtual space, going back to old shots and making changes is a simple task. If you wanted to do this photographically the set would have to be rebuilt, usually costing the same as the original shot. Being able to re-render an existing set takes a matter of hours as opposed to days at a fraction of the cost.
Every Item within the images needs to be created in 3D; sometime these 3D models are created for the manufacturing process and therefore may exist in some form.
These 3D models will then have textures applied, this is the term used for all the elements of the items surface finish, colour, sheen, texture and reflective properties.
The 3D models just as in real life need to be ‘photographed’ in a virtual photographic studio where all the skills required in the real world photography are used here. Camera compotation, studio lighting, styling and art direction.
This all now exists in a 3D virtual world and can be re-visited at any point of time to make alteration such as colour, camera angles and even to create web videos or to produce TV advertisements.Click here to see the animation
