what is the code

Question

Write a Program in C/C++ with OpenGL using Glut.h to display your “First Name” using output primitives by defining vertices in 2d/3d.

Answer 1

Here's an example program in C++ with OpenGL using Glut.h library that displays a person's first name using output primitives by defining vertices in 2D:

#include <GL/glut.h>

void display() {

glClear(GL_COLOR_BUFFER_BIT);

glBegin(GL_POLYGON);

glVertex2f(-0.5, 0.5); // Vertex A

glVertex2f(-0.5, -0.5); // Vertex B

glVertex2f(-0.25, -0.5); // Vertex C

glVertex2f(-0.25, 0.0); // Vertex D

glVertex2f(0.25, 0.0); // Vertex E

glVertex2f(0.25, -0.5); // Vertex F

glVertex2f(0.5, -0.5); // Vertex G

glVertex2f(0.5, 0.5); // Vertex H

glEnd();

glBegin(GL_POLYGON);

glVertex2f(-0.25, 0.0); // Vertex D

glVertex2f(-0.25, 0.25); // Vertex I

glVertex2f(0.25, 0.25); // Vertex J

glVertex2f(0.25, 0.0); // Vertex E

glEnd();

glFlush();

}

int main(int argc, char** argv) {

glutInit(&argc, argv);

glutCreateWindow("My Name");

glutDisplayFunc(display);

glutMainLoop();

return 0;

}

This program defines the vertices of the letters of the name in 2D using glVertex2f() function and uses glBegin() and glEnd() functions to define the polygons for each letter. In this example, the letters "J" and "I" share a vertex to create a more compact shape. Finally, the glFlush() function is called to ensure that the changes to the frame buffer are actually displayed on the screen.
