Graphics Editor

Graphics Editor

‘A picture is worth a thousand words’ goes the ancient Chinese proverb. This has become a cliché in our society after the advent of inexpensive and simple techniques for producing pictures.

           

  Computers have become a powerful medium for the rapid and economical production of pictures. There is virtually no area in which graphical displays cannot be used to some advantage. Graphics provide a so natural means of communicating with a computer that they have become widespread. Interactive graphics is the most important means of producing pictures since the invention of photography and television.

       

   The general purpose graphics package provides users with variety of functions for creating and manipulating pictures. Interactivity is implemented by using buttons, which when clicked, using a pointing device such as a mouse, calls the specified function containing the algorithm.

        

 Graphics Editor is a software tool that helps the user to create some painting on the screen to do some operation on it. This is a simple and a user friendly graphics editor based on the Windows platform. It consists of the following basic facilities:

• Geometrical shapes such as straight line, parallel lines, circle, ellipse, spiral, square and rectangle can be drawn.
• Some other features include flood fill, eraser, free hand drawing and text typing.
• A range of colors and patterns has been provided for the user to choose from.

The position of the mouse pointer is shown in the status bar at the bottom of the screen.   In short all the basic features necessary for the graphics editor have been provided. Care is taken to provide an easy-to-use mouse interface involving an icon-based interaction to provide an intuitive feel to our graphics editor.

Helicopter

HELICOPTER

It is one button game. The idea behind the game is to navigate the helicopter through a cave avoiding obstacles and avoiding hitting the roof of the cave or the floor.

Initially one needs to press the left mouse button to make the copter move upwards, once released then it goes down, if not it goes up again, concentrate on left button to skip the obstacles. The goal is to go as far as possible.

Mouse event is generated when the mouse is moved and one of the buttons is pressed.

             This is a simple interactive graphics program .It is extremely user friendly and has the features, which makes an Opengl application .It mainly demonstrates the simple application of Opengl in gaming applications.

It has an open source code and no security features have been included. The user is free to alter the code for further enhancements to either the front end or the back end. The basic minimal features such as built-in functions have been included in this simple graphics program.

Screen Shots

Initially the instructions to play the game is displayed on the console screen

We can see the copter in blue color, roof and floor of the cave in green color and obstacle in red color. As the copter navigates through the cave without hitting the obstacles the score will be incremented and will be displayed as shown.

The above picture is shown where the copter is hitting the obstrucles after that it will display ‘GAME OVER’.

When the game is over the above screen is diaplayed with the message “GAME OVER” .

Windmill

Windmill

In this project we designed the simulation of windmill using OpenGL. We used transformation functions like translate and rotate functions to design blades of the windmill. We used many OpenGL inbuilt function to design the structure of windmill.

This project consist of many user defined function such as increasing windmill fan speed, decreasing windmill fan speed, side views, front and back views, custom angle of rotation of entire windmill structure.

It provides several options which can be interacted through menus. The user can also interact with program through mouse, keyboard functions. The options provided by the menu are views like side view, back view, front view, custom view. Using mouse, if we click left side it rotates to left and on successive clicking speed increases, if we click right button speed decreases and on successive clicking, it turns rotating towards right and vice versa.

We can rotate the entire windmill with respect to its axis using the arrow keys of keyboard. It can be rotate through 360⁰

Simulation of Windmill is a designed and implemented using a graphics software system called OpenGL which has became a widely accepted standard for developing graphic application. Using openGL functions user can create geometrical objects and can use translation, rotation, scaling with respect to the co-ordinate system.

 The project Visual Transformation Techniques using openGL is based on Rotation and Translation processes using shading effects and is demonstrated using Visual C++.

               The development of the Simulation of Windmill project has given us a good exposure to OpenGL by which we have learnt some of the technique which help in development of animated pictures, gaming. Hence it is helpful for us even to take up this field as our career too and develop some other features in OpenGL and provide as a token of contribution to the graphics world.

Simulation of Windmill consist of many user defined function such as increasing windmill fan speed, decreasing windmill fan speed, side views, front and back views, custom angle of rotation of entire windmill structure. All these function makes this project an example of animation in OpenGL.

Steam Engine

STEAM ENGINE

A steam engine is a heat engine that performs mechanical work using steam as its working fluid. Heat is obtained from fuel burnt in a closed firebox .The heat is transferred to the water in a pressurized boiler, ultimately boiling the water and transforming it into saturated steam. Steam in its saturated state is always produced at the temperature of the boiling water, which in turn depends on the steam pressure on the water surface within the boiler. The steam is transferred to the motor unit which uses it to push on pistons to power machinery. The used, cooler, lower pressure steam is exhausted to atmosphere.

The project simulates the working of a steam engine. It illustrates how the linear motion of the piston is converted into rotary motion. The engine is initially at rest. On right clicking, the user is provided with a menu which provides five options-shaded, animate, increase speed, decrease speed, transparent.

The animate option starts the steam engine from rest or stops the engine if it is running. The speed of the engine can then be increased by the increase speed option or decreased by the decrease speed option. The texture of the engine can be changed by the shaded option.There are two textures. One being the normal solid fill and the other being wireframe. The transparent option makes the front portion of the cylinder transparent and shows the up and down motion of the piston.

The simulation helps in understanding the working of the engine. It clearly shows how the linear motion is converted into rotary motion.
