Assignment No. 01 Semester: Spring 2019
CS602: Computer Graphics

Total Marks: 20

Due Date:12/05/2019

Objective
The objective of this assignment is to;
♣ Learn and practice basic concepts of computer graphics like pixels, lines, text etc using Dev-C++. (You can download Dev-C++ setup from LMS)
♣ Learn to draw lines by using graphics library functions.
Instructions:
You have to do the following steps first in order to perform the task.
1. Install Dev-C++ from your LMS.
2. Read out the file “Add graphics in Dev cpp” thoroughly and follow the instructions in the file properly provided to you on your LMS.
  Please read the following instructions carefully before submitting assignment:
3. You should consult the recommended books, PowerPoint slides, Handouts and video lectures to clarify your concepts.
4. You can take any help from your provided labs.
5. It should be clear that your assignment will not get any credit if:
  • The assignment is submitted after due date.
  • The assignment is copied from Internet or from any other student.
  • The submitted assignment does not open or file is corrupt.
  Submission
  You are required to submit your solution through LMS in zip format containing following files.
  ♣ Your Project in zipped form containing both .dev and .cpp file.
  ♣ An MS Word document containing screenshot of your program output/execution and your own Student-ID must be visible in the screenshot.
Note: No assignment will be accepted after the due date through email in any case (load shedding, server down, internet malfunctioning etc.).
It is recommended to upload solution file at least two days before its closing date.

For any query about the assignment, contact at [email protected]

TASK Marks=20
A graphic designing company ABC needs your services to write a code for a particular design consisting of lines only. The design will be used for greeting cards printing, mug art printing and t-shirts printing in future. Following design is selected for this purpose:

As you can see there is a rectangle in the centre of the screen. Inside the rectangle there are three horizontal lines above and below the rectangle at equal space.
Inside these three lined set there are two patterns. First pattern is the horizontal lines equidistance from each other followed by vertical lines. Second pattern is equidistance vertical lines followed by horizontal lines. The total number of lines in both patterns are equal.
(Hint: You can use loop for each pattern)

Now you have to write a code for generating the above design. Your actual Student-ID should be displayed at the top left corner of the screen.
Discussion is right way to get Solution of the every assignment, Quiz and GDB.
We are always here to discuss and Guideline, Please Don't visit Cyberian only for Solution.
Cyberian Team always happy to facilitate to provide the idea solution. Please don't hesitate to contact us!

@zaasmi said in CS602 Assignment 1 Solution and Discussion:

Question 1) Write a program in Dev C++ to draw a circle. Also, use the flood fill algorithm to fill the circle with different lines of red color. The output of your program should like the below image:

Solution:
// C Implementation for setfillstyle // and floodfill function #include <graphics.h> // driver code int main() { // gm is Graphics mode which is // a computer display mode that // generates image using pixels. // DETECT is a macro defined in // "graphics.h" header file int gd = DETECT, gm; // initgraph initializes the // graphics system by loading // a graphics driver from disk initgraph(&gd, &gm, " "); // center and radius of circle int x_circle = 250; int y_circle = 250; int radius=100; // setting border color int border_color = WHITE; // set color and pattern setfillstyle(HATCH_FILL,RED); // x and y is a position and // radius is for radius of circle circle(x_circle,y_circle,radius); // fill the color at location // (x, y) with in border color floodfill(x_circle,y_circle,border_color); getch(); // closegraph function closes the // graphics mode and deallocates // all memory allocated by // graphics system closegraph(); return 0; }

Q. 1 Solution Idea

a. Final intensity of light is (0.4,0.7,0) +(0.2,0.1,0.5) +(-0.5, -0.6,0.5) +(-0.1, -
0.2,0) = (0,0,1)

b. Overall Contribution: id ⨂ cs = (0,0,1) ⨂ (0.5,0.7,0.8)
= (0,0,0.8)

c. Red and Green components will remain absent from the scene

d. The object will look blue in the presence of light sources.

@wafa-sehar said in CS602 Assignment 3 Solution and Discussion:

Question # 2:
What are the Open GL Buffers and how can you create and allocate these buffers. Discuss with an example.

Nearly everything you may ever do with OpenGL will involve buffers full of data. Buffers in
OpenGL are depicted as buffer objects. As with several things in OpenGL, buffer objects are
named using GLuint values. Values are stored using the glGenBuffers () command.
Example: void glGenBuffers(GLsizei n, GLuint *buffers);
After calling glGenBuffers(),you will have an array of buffer object names in buffers, but at this
time, they’re simply placeholders. They’re not really buffer objects yet. The buffer objects
themselves don’t seem to be really created till the name is first sure to one of the buffer binding
points on the context. this can be important as a result of OpenGL could build choices regarding
the most effective way to assign memory for the buffer object based on where it’s bound.
