REAL TIME GRAPHICS AND RENDERING

INTRODUCTION

In the field of computer science is divided in different aspects according to its dealing with.
This have been citened from the previous field such as cryptographic (deal with encryption and decryption), finger print recognition, iris recognition and so many which driven with its own function.
Computer graphics: This is an art of computer based mathematical representation of geometric objects such as building a vehicles or any object including humans. But also there are different concepts which accompanied with computer graphics.
Raster: This is an image that displayed through the arrangement of pixels on screen.
Vector images: This is an image created by using mathematical algorithms and geometry functions to represent its size and shapes.
Model: This is 2D image or 3D objects created to resemble the actual thing. Therefore this all can be decorated to make good impression.

HISTORY OF COMPUTER GRAPHICS

After the invention and rapidly increase in software engineering in 1960’s that the rapidly developed of CG and rendering. In 1961 the first video game was created and named space war by Steve Russell.
But a program which ever utilized a complete graphical user interface was created in 1963 and named sketchpad. In 1971’s most important advancements in computer graphics microprocessor was seen.
In apple released the first personal computer to use a graphical interface. Finally during 1990’s a vast of film industries present has been incorpating CG in the business which made pressure CG and rendering.
Also there are some steps in designing the images in the CGI such as pre – design (this means before drawing they must be planning first). Modeling (modeling the process of a creating models), texture, animating (the rapid display of a sequence of images of 2 –D or 3 – D) and Rendering (this referred to as a process of converting vector images to raster image).
Another technology applied is open graphics language (OGL), this OGL have the steps in drawing.


- Draw basic primitives
- Matrix operation
- Hidden surface Removal
- Lighting and shading
- Texturing
- Fixed operations
- GPU Computation

ADVANTAGES

It minimizes the cost of actual production.
It gives more flexibility and allows complex effects and movies to be produced in film industries. This is due to the integrated software which make things as reality.
In medicine field, CG allow different simulation of parts of the body and organ which make it easily in understand and critical curing.
But the main disadvantages of CG and rendering it take a lot of opportunity which could be employment to the people.

CONCLUSION
Therefore CG and rendering is useful in our daily life when it used in efficiently way, it can be more applied in building simulation, films and all new technology which can be easily in conducting modern science.
