The project “WINDMILL” is about to show how we efficiently make use of renewable energy using OpenGL function. We have used simple OpenGL functions to draw a rotating fans and We show the generation of electricity when the fans are rotated. Using this mechanical energy we can generate the electricity which is nonrenewable.
It provides most the features that a model should have. It is developed in C. It has been implemented on FEDORA platform. The graphics package designed here provides an interface for the users for handling the display and manipulation of basic picture objects. It can also perform operations on selected objects like translation.
The change in direction of rotation of fan in wind mill and generation of electricity is the result of this project. It provides most of the features that a 2D graphic editor should have. It is developed in C programming language and implemented on the FEDORA platform. The graphics package designed here provides an interface for the users for handling the display and manipulation of basic picture objects like point, line, etc. The interface is user-friendly.

INTRODUCTION About OpenGL
The Computer Graphics is one of the most effective and commonly used methods to communicate the processed information to the user. It displays the information in the form of graphics objects such as pictures, charts, graphs and diagram instead of simple text.
OpenGL is supported on all platforms. Drivers are available virtually for all graphics cards. OpenGL’s extensive capabilities and well-defined architecture supports advanced concepts such as texture mapping, compositing and programmable shaders. It is easy to learn, and it possesses most of the characteristics of other popular graphics systems. The main features of OpenGL are
It provides 3D geometric objects such as lines, polygons, triangle, meshes, spheres, cubes, quadric surface, and curved surfaces.It provides 3D modeling transformations and viewing functions to create views of 3D scenes using the idea of a virtual camera. It supports high-quality rendering of scenes, including hidden-surface removal, multiple light sources, material types, transparency, textures, blending, fog It provides display lists for creating graphics caches and hierarchical models. It also supports the interactive “picking” of objects.It supports the manipulation of images as pixels, enabling frame-buffer effects such as ant aliasing, motion blur, depth of field and soft shadows.
A key feature of the design of OpenGL is the separation of interaction from rendering. OpenGL itself is concerned only with graphics rendering. Abbreviations: GLUT- OpenGL Utility Toolkit GLU- OpenGL Library Utility CSE,BITM

FUNCTIONS The Graphics Package is designed using the in-built graphics library. The objects, which are drawn, are stored as functions that can be used according to the requirements. Ease of understanding and speed of working are two main requirements for it, which should be kept in mind during phase of design and implementation.
Basic Design The 2-D transformation project has been developed in C that also provides an inbuilt graphics library through "GL/glut.h".
Modules and their descriptions Header files
“stdio.h” : This is the header file that includes the functions like printf(), scanf() for read and write operations. It also includes the file handling like open(), close(), etc.
“stdlib.h” : This is used to get some standard libraries.
“GL/glut.h” : This is to include the graphics built in openGL function and utilities to build and implement our customized graphics packages.
Inbuilt functions
glClearColor() : C Specification void glClearColor (GLfloat red, GLfloat green, GLfloat blue, alpha);
GLfloat
Description: This function sets the color value that is used when clearing the color buffer.

CONCLUSION This project is implemented using OpenGL. We have used simple OpenGL functions to draw a rotating fans and we show the generation of electricity when the fans are rotated. Wind power is the conversion of wind energy into a useful form of energy, such as using rotating fans we can generate the electricity which is used for daily routines.
This project also helps us to analyze how we can use the different standard functions for creating the changes of rotation of fan in wind mill.(clockwise, anticlockwise). This package is very useful for the users since it provides the basic information about various OpenGL functions.
This product has been demonstrated to fulfill the requirements. The functionality of all the modules and the module level integration is found to be satisfactory.
This graphics model is very useful, one showing the rotational changes implementation. We have tried our best to make this modeling very realistic, so that the user does not face any trouble when seeing over from any real life to this highly useful graphics model.
Thus we have completed our project successfully by learning the concepts of OpenGL and Computer Graphics.
