Unit 14: Animation in Computer Graphics

14.3 Summary

• Computer graphics deals with high dimensional visual objects with special effects and virtual
effects along with animation which is the recent development.
• The increase in the sophisticated animation systems has led to the generation of high quality
computer animation making it simpler.

• Simulation softwares are used for graphical simulations.
• This is done through optical illusion of motion by employing the phenomenon of persistence of
vision in which images can be created and depicted in several ways.
• Animation software is made up of the tricks and best practices of conventional animation.

14.4 Keywords
Cloning: Make exact copy of a file.
Composited: Assembled, combined.

Cuneiform: Writings related to ancient times (Babylonians and Persians). These characters are formed
by the arrangement of wedge-shaped elements.
Curvature Coloring: The regions with similar curvatures are colored with similar colors.
Deciphering: To discover the meaning of something written in a hidden manner.
Digital Painting: It is a painting method that involves using digital tools and software to paint the
surface required.
GPU: Graphical or visual processing unit.
Novice: A person who is not experienced in a job or a fresher in any field.
Paleolithic: Relating to Old Stone Age.
Pictograms: Pictograms are also known as pictographs. The meaning of objects is conveyed pictorially
based on their resemblance to the object.
Plotters: Plotters are printing devices used for printing vector graphics.
Pre-warping: It is the method used for solving problems related to warping.
Raking Lights: Moving light.
Reflectance: It is the ratio of the total amount of radiation of light that is reflected by a surface to the
total amount of radiation that is incident on a surface.
Rendering Time: Rendering is the process of generating an image from a model by using computer
graphics. The time used for the purpose of generation of the image is known as rendering time. The
Graphical Process Unit (GPU) is the built-in device that helps the Central Processing Unit (CPU) to
perform complex rendering.
Tactile Texture: Pleasant texture.
Tweening: It is an interpolation technique used in an animation program to generate extra frames
between the key frames that a user creates. It is considered as an advantageous method, as the user does
not draw every frame.
Warping: Warping is a process of digitally manipulating an image with the aim of distorting the image.
It can also be used to rectify image distortions for creative purposes known as morphing.
