Origins of CGI Animation
CGI animation has a long history and the exact time of its origin is blurred, but it is widely believed that the technology was first used in 1958. In this section, we’ll delve into the early experiments and breakthroughs that laid the groundwork for the CGI animation we know today.
Early Experiments and Breakthroughs
From the first computer-generated animation movie Alfred Hitchcock’s Vertigo in 1958 to the development of influential algorithms in the 1970s, the roots of CGI animation were planted in the early days of computing.
The technology was in its infancy but the potential was very clear to the film-makers and other industries. Now it has become very clear why CGI was able to grab the attention of many.
Furthermore, the success of earlier experiments in CGI animation furthered the development of the technology. There were some groundbreaking movements which changed the course of things for this infant technology.
Milestones in CGI Animation Development
What we see in movies like The Avengers and Avatar is the best and most advanced use of CGI animation. But it has not always been like this. CGI animation has achieved many milestones to get to where it is now.
The movie Westworld 1973 represents the first and most important of these milestones. It was the first movie to use digital image processing which was groundbreaking for the animation industry.
What followed was the sequel of the same movie Futureworld which came out in 1976. It was the first movie to use 3D computer graphics to create an animated hand and face. After that what followed was a decade of exceptional movies and it is still going on.
CGI Animation in Film History
This section explores the significant impact of CGI animation on the film industry, leading to groundbreaking achievements in visual storytelling.
First CGI Animated Movie
The emergence of the first CGI animated movie marked a turning point in animation history. As discussed earlier, the first CGI animated movie was Vertigo produced in 1958. The amazing fact about this movie is that the traditional CGI technique was not used. Instead, a specially made mechanical computer was used to make this amazing movie.
Other than that, when we talk about the proper use of CGI animation Westworld is considered to be the very first one made using this technique. The movie was released in 1973. The use of CGI in this movie seemed to work very well. The movie was a super hit and was praised by the general public
The Very First Characters Made Using CGI
There are many views about which was the first character made using CGI technology. But two characters stand out in this regard.
The first one is the character of the stained-glass knight in the 1985 movie “The Young Sherlock Holmes.” The role of the knight was no more than 30 seconds but it took six months to make it. The character is far from perfect, but it had made a lot believe that CGI has a great future.
The second character is Jar Jar Binks in “Star Wars: Episode I – The Phantom Menace.” These two characters are the two most prominent contenders for the first character made using CGI. As compared to the character of the stained glass knight this was a much better character and the general public really appreciated this CGI Character. It was far from perfect, but was a significant milestone.
The Process of Creating CGI Animation
Understanding the complex process behind CGI animation is vital to appreciate its artistry fully. From pre-production to post-production, we will guide readers through the meticulous steps that bring digital worlds to life.
It may seem easy on the eyes but a small mistake in the making process can ruin the whole product. So, there are certain steps which are to be carefully followed.
Pre-production Phase
| 1. Careful Planning | Before any animation begins, careful planning and conceptualization are essential. You need to make sure of what you are making and for what purpose. As long as the first step is not perfect there is no chance of getting perfect end results. |
| 2. Concept and Storyboarding | The second and most important part is the concept and story of the movie or anything else. Once you have a strong story built up it can attract the attention of the audience and you are ready to roll. |
| 3. Character Design and Modeling | Last but not least pre-production phase is the design and modelling of the characters. You need to have a proper plan for this as well. You can imagine that it is not easy to pull off the character of a dragon for a movie which actually looks real. You probably have seen the character of Smaug in the Hobbit movie. It does not look like a CGI-made dragon. So, to achieve accuracy like that designing and modelling has to be perfect. |
Production Phase
| 1. Texturing and Shading | In this stage, artists add realistic textures and shades to the digital objects created during the modelling phase. Texturing involves applying detailed images or patterns onto the 3D models, giving them the appearance of various materials like wood, metal, skin, or fabric. Shading is the process of defining how light interacts with the surfaces, determining how reflective, matte, or translucent they should be. Example: Imagine a CGI-animated movie where the main character is a dragon. In this stage, artists would apply detailed textures to the dragon’s scales, giving them a realistic and intricate appearance. The dragon’s skin may be shiny and reflective, while the eyes would have a glossy, glass-like texture. |
| 2. Rigging and Animation | Rigging involves creating a digital skeleton for characters and objects, enabling animators to control their movements and expressions more easily. Animators then bring the characters to life by creating keyframe animations or using motion capture data to produce natural and fluid movements. Example: In a CGI-animated TV series about a group of robots, rigging would involve creating a skeleton for each robot character. Animators would then use the rig to animate the robots’ actions, such as walking, talking, or performing complex actions during action sequences. |
Post-production Phase
| 1. Rendering | Rigging is the process where all the individual elements of the CGI animation are combined to create the final visual output. This phase involves computing the lighting, shadows, and reflections, as well as processing the textures and animations to generate the final frames or images that make up the animated sequence. Example: In a CGI-animated fantasy film, the rendering process would take all the elements, including characters, backgrounds, and special effects, and combine them to produce the final frames for each scene. This step brings the entire virtual world to life with realistic lighting and effects. |
| 2. Compositing and Editing | In this final stage, compositing artists integrate the CGI elements with live-action footage (if any) and add additional visual effects to create a seamless and cohesive final product. They adjust colours, add depth-of-field effects, and ensure that CGI elements interact naturally with the live-action components. Example: Consider a sci-fi movie that blends live-action scenes of actors with CGI-created alien creatures and spaceships. In the compositing and editing stage, artists would merge the live-action footage with the CGI elements, making it appear as though the actors are interacting with the alien creatures and the spaceships are seamlessly integrated into the scenes. |
Popular Software for CGI Animation
There are a number of amazing software which are used to make CGI animation. Some of the well-known software are Autodesk Maya, Blender, Pixar’s RenderMan, SideFX Houdini, and Adobe After Effects.
