Computer Animation==
Computer animation, is a subfield within computer graphics which is created by using 3D computer graphics, 2D graphics can still be used as they have faster real-time rendering needs. [1] it is a successor to the use of stop motion by suing 3D models and frame by frame animation of 2D illustrations.
3D Animation differs from 2D Animation as 2D Animation uses foreshortening and perspective to create space and depth and it can only be measured in height and width as it exists on a 2D Space while 3D animation is different as it can only be made with the use of a Computer , it can do the impossible in 2D Animation such as having rotating 360 degrees, volume and more.

John Whitney was included as one of the first people to have experimented with computer graphic animation which occurred in 1940's and 50's, he is also known as the father of computer animation. His early films were impressive as they were made on a rig with an anti-aircraft analog computer and is known to be impressive as programmable digital computers did not come about until 1957. [3]
History of 3D Animation
3D animation made it's first appearance in 1972 by Ed Catmull who was the founder of the largest 3D animation studios of all time, 'Animation' as the word is translated from the French as it means 'soul', this is the reason as to why animation production is also known as the ensoulment of characters. [4]
Before computers, the early animators would use Clay and of the sort to form shapes, and they would move that clay to form every little bit of shot, which would then get shot together after it has been pieced for it to have been created as an animation. This is called stop motion or claymation, Stop motion is very time consuming and it has been used in shows when it was first aired in 1956 on Gumby , [Wallace and Gromit]] and also Robot chicken. [5]
By 1980's many of the movies would be using 3D animation techniques that were developed and this would be common, Turner Whitted introduced Ray tracing which is known as rendering technique that gives realistic results, in the 1990's the industry of animation has increasingly showed more success commercially and Hollywood started introducing this type of animation in their well known movies such as Terminator 2 , Toy story, Beauty and the Beast and much more. [6] Pixar created their well known movie Toy Story in 1995 by using a complex system of model articulation as well as motion-control coding. [7]
3D Animation Software's
One of the biggest companies around the world which is Pixar uses a VFX software called RenderMan , this software has been used in their well known movies such as Frozen, The hobbit, Toy Story and many other well known movies, Renderman has been around since 1984. [8]
The software Presto is also known to be used by Disney for their 3D Animations, Presto is used for the animation, scene layout, rigging and other features that it has, and it is used for Disney's final rendering for their movies. [9]
Houdini is also used by Disney for their 3D animations, this software mainly specialises in effects and it si designed from the basics to be a procedural system which enables the designers to have freedom while using it, it also powerful asset building tools. [10]
