Write a program in C/C++ using OpenGL that draws the following figure:
To draw the given figure using OpenGL in C/C++, you'll need to create a series of vertices that form the shape of the arrow. Below is a basic example of how you can create this using OpenGL:
#include <GL/glut.h>
void display() {
glClear(GL_COLOR_BUFFER_BIT);
// Start drawing the shape
glBegin(GL_LINE_LOOP);
// Left half of the shape
glVertex2f(-0.5f, 0.0f);
glVertex2f(-1.0f, 0.5f);
glVertex2f(-1.0f, -0.5f);
// Bottom part of the shape
glVertex2f(-0.5f, -0.5f);
glVertex2f(-0.5f, -0.75f);
glVertex2f(0.5f, -0.75f);
glVertex2f(0.5f, -0.5f);
// Right half of the shape
glVertex2f(1.0f, -0.5f);
glVertex2f(1.0f, 0.5f);
glVertex2f(0.5f, 0.0f);
// Top part of the shape
glVertex2f(0.5f, 0.5f);
glVertex2f(-0.5f, 0.5f);
glEnd();
glFlush();
}
int main(int argc, char** argv) {
glutInit(&argc, argv);
glutCreateWindow("OpenGL Arrow");
glutInitWindowSize(500, 500);
glutInitWindowPosition(100, 100);
glutDisplayFunc(display);
glClearColor(1.0, 1.0, 1.0, 1.0);
glColor3f(0.0, 0.0, 0.0);
gluOrtho2D(-1.5, 1.5, -1.0, 1.0);
glutMainLoop();
return 0;
}
glBegin(GL_LINE_LOOP)
initializes a loop of connected lines to form the shape as specified by your vertices.glColor3f(0.0, 0.0, 0.0)
and glClearColor(1.0, 1.0, 1.0, 1.0)
.Compile and run this code using an OpenGL setup to see the figure drawn on the window. Adjust coordinates if needed for your specific requirements.
