When designers refer to CGI (computer generated imagery), they mean specific tools and processes used to create photo-realistic images. The term is often associated with visual effects in movies, like making Godzilla appear on screen (the 2014 version, not the original from 1954), but CGI is being used more and more for designers and manufacturers in every field.
The CGI process starts with the construction of 3D models. These can be made from scratch, built from CAD designs, or made from technical or artistic references.

After creating the models, textures are applied, the lighting is created, and images are rendered from virtual cameras. When an image is rendered, that just means the digital scene is being “shot” from a particular angle, or in the case of an animation, the scene is being shot from many angles in a sequence of images.

The results are photo-realistic images of anything you can envision, from elaborate architecture to sports cars or detailed product shots. The advantage of CGI is that the models these images are made from can be pulled up and “re-shot” (re-rendered) in different arrangements, from different angles, or with different props in almost no time at all. Forget about setting up another photoshoot or doing touch-ups after the fact.

WHY USE CGI?

CGI is saving forward-thinking companies time and money. It also increases quality and control of the final product.

Here’s how.

CGI models are made once, and they can be reused and “photographed” over and over again. For businesses that need multiple angles or different variations of a product, creating a CGI model allows them to produce all the photography that is needed without the time and cost of organizing photoshoots for each variation.
