The generation of graphical output using a computer
by developing software to accomplish the task
by using pre-existing application software like Photoshop, 3D Studio Max, Maya, …
Now, Let’s talking about Computer Graphics.
We can classify computer graphics by two methods.
Computer Graphics can be generated by developing …
It means, using c, c++, java, java3D, OpenGL, Direct-X,…
And, Computer Graphics can be generated by using …Maya, PhotoShop, Flash…
In this class, we will study OpenGL program language to generate computer graphics.

He is Geri, character of Geri’s game and Toy Story II.
Geri's Game received the Academy Award for Best Animated Short Film in 1998
You must see Toy Story II If did not see yet.
Please check whether this short is include in video.
This is a scene that a person plays chess game alone.

Modeling
The creation of mathematical models of 2D and 3D objects
Computer generated models, or 3D models, are built in the 3D environment of a computer.
Due to the nature of digital technology, computer generated models are becoming very popular, even out-side of the cinema industry.
These models can then be zoomed in or rotated to any view, or even animated to show a real-time walk through or fly-by.

Animation
Topics include traditional principles of animation, kinematic and dynamic modeling techniques, physical simulation, procedural methods, and motion capture based animation.
You can see the motion capture equipment at the DIDIC in the Culture Center Building.
Next time, we will wear special cloth such as diving suit and receive your motion capture data.
This is simple than solve complex mathematical problem
You must solve partial differential equation of inverse kinematic model..
This equipment is about 100,000 US dollar.

Rendering
These models, starting as a wire frame model, are digitally wrapped with textures and rendered with reflections, transparencies, and shadows to give a photo-realistic view of the object or building.

CAGD
Computer

Geometric
Design
We can classify computer graphics by many research area.
CAGD is one of major research field of modeling.
CAGD is computer aided geometric design's abbreviated word.
Next picture is an instrument in the Norway Viking museum.
It was a necessary tool when manufacture ship.
this is a method to make a free smooth curve.
Maybe it is a traditional geometric design tool.
These days, we can get the smooth curve using computer.

Pierre BEZIER died on November 25, The following short biography has been published in volume 22, number 9 (november 1990) of "Computer Aided Design", a special issue devoted to Bezier techniques. Pierre Etienne Bezier was born on September 1, 1910 in Paris. Son and grandson of engineers, he chose this profession too and enrolled to study mechanical engineering at the Ecole des Arts et Metiers and received his degree in In the same year he entered the Ecole Superieure d'Electricite and earnt a second degree in electrical engineering in In 1977, 46 years later, he received his DSc degree in mathematics from the University of Paris. In 1933, aged 23, Bezier entered Renault and worked for this company for 42 years. He started as Tool Setter, became Tool Designer in 1934 and Head of the Tool Design Office in In 1948, as Director of Production Engineering he was responsable for the design of the transfer lines producing most of the 4 CV mechanical parts. In 1957, he became Director of Machine Tool Division and was responsable for the automatic assembly of mechanical components, and for the design and production of an NC drilling and milling machine, most probably one of the first machines in Europe. Bezier become managing staff member for technical development in 1960 and held this position until 1975 when he retired. Bezier started his research in CADCAM in 1960 when he devoted a substantial amount of his time working on his UNISURF system. From 1960, his research interest focused on drawing machines, computer control, interactive free-form curve and surface design and 3D milling for manufactoring clay models and masters. His system was launched in 1968 and has been in full use since 1975 supporting about 1500 staff members today. Bezier's academic career began in 1968 when he became Professor of Production Engineering at the Conservatoire National des Arts et Metiers. He held this position until He wrote four books, numerous papers and received several distinctions including the "Steven Anson Coons" of the Association for Computing Machinery and the "Doctor Honoris Causa" of the Technical University Berlin. He is an honorary member of the American Society of Mechanical Engineers and of the Societe Belge des Mecaniciens, ex-president of the Societe des Ingenieurs et Scientifiques de France, Societe des Ingenieurs Arts et Metiers, and he was one of the first Advisory Editors of "Computer-Aided Design".

OpenGL
OpenGL is a software interface to graphics hardware. This interface consists of about 120 distinct commands, which you use to specify the objects and operations needed to produce interactive three-dimensional applications.

23. Computer Graphics, Lee Byung-Gook, Dongseo Univ.
OpenGL
OpenGL is designed as a streamlined, hardware-independent interface to be implemented on many different hardware platforms. To achieve these qualities, no commands for performing windowing tasks or obtaining user input are included in OpenGL; instead, you must work through whatever windowing system controls the particular hardware you're using.

OpenGL
OpenGL doesn't provide high-level commands for describing models of three-dimensional objects. Such commands might allow you to specify relatively complicated shapes such as automobiles, parts of the body, airplanes, or molecules. With OpenGL, you must build up your desired model from a small set of geometric primitive - points, lines, and polygons.
