CGI is an application of Computer
Graphics to create or contribute to images in art, printed media, video games,
films, commercials, etc. The visual scenes may be static or dynamic and may be
2D or 3D. Think of it this way, CGI attempts to do with numbers, what a camera
does with light. Our world is bound by many physical constraints, but with CGI
we can create many things that are impossible in reality. One may wonder what
would be the advantage of such a tool; let’s go over some of them.

| Medical Visualizations |
In medicine, Computer generated
anatomical models are used for both instructional and operational purposes.
Using CGI, a three dimensional image can be created from a bunch of single
slice X-rays which can help in a speedy and accurate diagnosis. In modern
medical applications patient specific models are constructed in “computer
assisted surgery”. For example, in a total knee replacement surgery, such a
model can be used to carefully plan a surgery.

CGI is also used in courtrooms to
help judges and jury to better visualize the sequence of events, evidence or
hypothesis. CGI is used in product advertisements; CGI can produce images with
no greasy fingerprints and are unmarred by dust, just perfect in every sense. CGI is also used for scientific visualization
to present meteorological data, medical imaging, architecture and technology.

| Avatar pushed CGI to a whole new level |
CGI is used in movies to create artificial
reality which is very close and in many cases better than actual reality. This
certainly helps in cutting down expenses. For example, in the movie Titanic, a
miniature model of the ship was created and extrapolated to create a real world
effect.
Thus, CGI has opened a new world
full of possibilities and it is up to us to explore and reap the benefits.

Hey Santrupti,
ReplyDeleteVery informative post about CGI and how it helps us in daily life! My sister actually does 3D modeling for patients with knee injuries to their meniscus so that was cool seeing that topic in your post. I really enjoyed the pictures you've included in your post. It shows how powerful our CGI tools are nowadays. I'm glad you included the sources of your information as well since most posts I've read didn't include theirs. Awesome post again and keep up the awesome work!
Hi Santrupti. Wow, I never heard this term before! Excellent examples made immediate sense about what a Computer generated Imagery is. I have been fascinated by computer graphics since I started playing computer games back in 2001. Computer graphics in whole is an exciting area and Avatar movie is just a wonderful example of it. Very nice blog, keep it up!
ReplyDeleteHello Santrupti,
ReplyDeleteYou did a great job describing computer-generated imagery and included various examples for the use of CGI such as anatomical models for surgeries, scientific visuals used for data research, and help visualize sequence of events used in courtrooms. You can almost see many movies use CGI and the movie Avatar is a brilliant example of great CGI being used to display stunning visual effects. Overall you did a great job on this post.
