Question 1: Implementing a Rotating Cube

Your task is to create a program in OpenGL that displays a rotating cube. Ensure smooth animation and user interaction to control the rotation speed.

Solution:
#include

float angle = 0.0f;

void display() {
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glLoadIdentity();
glTranslatef(0.0f, 0.0f, -5.0f);
glRotatef(angle, 1.0f, 1.0f, 1.0f); // Rotation along all axes
glColor3f(1.0f, 0.0f, 0.0f); // Red color
glutWireCube(2.0f); // Draw wireframe cube
glutSwapBuffers();
}

void update(int value) {
angle += 2.0f; // Increment angle for rotation
if (angle > 360) {
angle -= 360; // Reset angle
}
glutPostRedisplay();
glutTimerFunc(16, update, 0); // Update every 16 milliseconds for ~60 FPS
}

int main(int argc, char** argv) {
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);
glutInitWindowSize(500, 500);
glutCreateWindow("Rotating Cube");
glEnable(GL_DEPTH_TEST);
glClearColor(0.0f, 0.0f, 0.0f, 1.0f); // Black background
glutDisplayFunc(display);
glutTimerFunc(16, update, 0);
glutMainLoop();
return 0;
}
In this solution, we utilize GLUT (OpenGL Utility Toolkit) to create a window and manage user input. The display() function handles rendering, while update() ensures smooth animation by updating the rotation angle periodically.
