Hope you all know that CGI stands for Computer-Generated Imagery. Today we will try to find out the reason behind the popularity of CGI animation technique. Before CGI two animation techniques were very popular one is hand drawn Traditional Animation and other is Stop-Motion Animation.

1. Reason CGI Animation Becoming Popular
Animation Technique
Hope you all know that CGI stands for Computer-Generated Imagery.
Today we will try to find out the reason behind the popularity of CGI animation
technique.
Before CGI two animation techniques were very popular one is hand drawn Traditional
Animation and other is Stop-Motion Animation.
In Traditional Animation artists used to draw the images on a transparent celluloid or
cel.
Traditional artists used to place cels on top of the background image to create multi-
layered frame.
And in case of Stop-Motion Animation clay model puppets were used.
But with the digital technology animation artists switched to computer screens instead
of pen and paper.
Animators can now place 3D models easily in three-dimensional space and can make
then interact with each other.
In the current scenario CGI animation technique has become popular and the other two
techniques have taken back seat.

2. CGI Animation Took The Front Seat
In the year 1993 Jurassic Park Movie changed the face of movies and entertainment.
Jurassic park proved that CGI movie not only look good but can become popular also.
Computer generated Dinosaurs with real actors created a fantasy world both for the
audience and film industry.
In case of Jurassic park dinosaur’s models were scanned with lasers and imported
within the computer.
For the first time animator added movement to bare-boned, wireframe models of
dinosaurs and the audience could watch something beyond their imagination.
Skins were added on the Dinosaurs with the help of 3D software.

3. Animators built the scene frame by frame with the software tools.
CGI allows the animator to create huge possibilities.
Various user friendly 3D software are available in the market today which helps the
artist to model any figure of their choice.
Computer generated 3D models look very similar to the real life figure as because of the
depth dimension.
Previously Traditional animated figures had only two dimension i.e length and breadth;
depth got added to the figures due to the 3D technique.
As because computer generated 3D figures looks more close to the real life character
both the animators and audiences is preferring CGI techniques.
Until 1990s CGI was used in a restricted manner but in 1995 movie Toy Story became
the first full-length CGI feature.
3D software became more user friendly by the time of Toy Story thus allowing small
team of animators to give life to the Woody Character.
Reduction in the price of computer allowed the animators to have their own digital set
ups to work with images and animation.
Young talented artists get interested towards the digital technology and they find this
CGI animation technique less painstaking.

4. CGI Modeling Technique
Autodesk Maya or 3D Max helps the animator to create any model using polygon
meshes.
3D models are gaining popularity in the entertainment fields due to their closeness with
the real figures.
Animators can give movements to each body parts of the computer generated models
something which is possible only in the CGI animation technique.
Detailing in the wrinkle skins, a blink of an eye, a lip movement looks more realistic in
the CGI animation techniques.
Development of RenderMan; a photorealistic 3D rendering software by Pixar Animation
Studio added more advancement in 3D technology.
RenderMan facilitates communication between 3D model, animation and render engine
to generate high quality images.
This rendering process has been used to provide stunning visual effects for Hollywood
blockbuster movies.
CGI is non-linear in nature; animators can work on different parts at the same time; one
team may work on body movement while another can work with facial expressions.
Background construction to lighting effects almost everything can be divided to
different artists to speed up the big project.

5. CGI Fur and Cloth Simulation
One of the toughest works of animator is to animate hair or fur of the creature.
But this work also became easy when Pixar developed fur simulation program called
Fizt; with Fizt program animators gave motion to Sulley’s fur in the movie Monsters
Inc.
Fur Simulation allowed the animators to animate the body fur in more real manner.
With CGI animators can give detailing touch to every each and every body parts of
creature or human.
Similar to Fur Simulation; CGI allows cloth simulation.
CGI allows cloth modeling in the 3D space; with cloth simulation artist can manipulate
colour, texture and crease of the cloth to make it look like real cloth.

6. CGI Simulation process has become very popular now and it has taken the animation
technique to the highly advanced stage.
CGI Simulation was quite impossible in the previous or hand drawn animation
technique.
CGI Motion Capture Technique
Motion Capture is another CGI technique where performance of the actors can be
recorded and transferred to the computer generated models.

7. This technique came to use in the year 2001 with the film The Lord of Rings where
master of motion capture director Andy Serkis used this technique for the character
Gollum.
Motion Capture is no doubt an exceptional CGI technique which put life into the images.
Within few years facial capture joined motion capture to make sure that each facial
expressions could be recorded and rendered.
Movie Avatar came into the theatres with the innovative facial capture CGI animation
technique in the year 2009.
And then there is no looking back, today to get to watch movies with Motion Capture
technique more often compared to last decades.
This technique not only portrays in-depth facial expressions but also human emotions.
In the year 2018 Andy Serkis thrilled the audience with his latest Motion Capture Movie
Mowgli: Legend of the Jungle.
Presently CGI animation has received a great media attention due to success of the
visual stunning movies at the theatres.

8. CGI Crowd Simulation
CGI technique can be used to create Crowd Simulation where huge crowd gets
movements.
Crowd Simulation is a unique aspect of CGI that has been applied to many Hollywood
movies like Lord of the Rings, Creed II and many more.
Hence here we gave you reasons about why CGI technique animation is becoming more
popular in this modern world.
