Question 1: Drawing a Triangle
Your task is to write an OpenGL program to draw a simple triangle on the screen.
c
Copy code
#include
#include
void display() {
glClear(GL_COLOR_BUFFER_BIT);
glBegin(GL_TRIANGLES);
glColor3f(1.0, 0.0, 0.0); // Red
glVertex2f(-0.5, -0.5);
glColor3f(0.0, 1.0, 0.0); // Green
glVertex2f(0.5, -0.5);
glColor3f(0.0, 0.0, 1.0); // Blue
glVertex2f(0.0, 0.5);
glEnd();
glFlush();
}
int main(int argc, char** argv) {
glutInit(&argc, argv);
glutCreateWindow("OpenGL Triangle");
glutDisplayFunc(display);
glutMainLoop();
return 0;
}
Solution Explanation: This program sets up a basic OpenGL window using FreeGLUT and draws a triangle with three vertices of different colors. The glBegin(GL_TRIANGLES) and glEnd() delineate the vertices of the triangle. Each call to glVertex2f specifies the position of a vertex in 2D space, while glColor3f sets the color of the vertex.
Question 2: Rotating a Cube
Now, let's move on to a more advanced problem: rotating a 3D cube continuously.
c
Copy code
#include
#include
#include
float angle = 0.0f;
void display() {
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glLoadIdentity();
glRotatef(angle, 1.0f, 1.0f, 1.0f);
glutWireCube(0.5);
glutSwapBuffers();
}
void update(int value) {
angle += 2.0f;
if (angle > 360) {
angle -= 360;
}
glutPostRedisplay();
glutTimerFunc(16, update, 0);
}
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);
glutDisplayFunc(display);
glutTimerFunc(16, update, 0);
glutMainLoop();
return 0;
}
Solution Explanation: This program initializes a 3D OpenGL window and draws a wireframe cube. The cube is continuously rotated using the glRotatef function, which takes an angle and an axis of rotation. The update function is called periodically to increment the rotation angle and redraw the scene.
