This document provides code to draw a star shape in Visual Studio using OpenGL and GLUT. It defines functions to render the scene in color, draw a polygon, and initialize the window. The drawPoly function contains the OpenGL commands to draw a star by specifying the vertex points of a polygon in 3D space and setting the color.

2. Visual Studio Code
#include<stdlib.h>
#include<GL/glut.h>
float red=1.0, blue=1.0, green=1.0;
void drawStar();
void drawPoly();
void renderScene(void) {
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(red,green,blue);
drawPoly();
glutSwapBuffers();
}

3. void drawPoly()
{
//1st Star
glBegin(GL_POLYGON);
glColor3f(red, green, blue);
glVertex3f(0.2,0.1,0.0);
glVertex3f(0.3,0.3,0.0);
glVertex3f(0.4,0.1,0.0);
glVertex3f(0.6,0.0,0.0);
glVertex3f(0.4,-0.1,0.0);
glVertex3f(0.3,-0.3,0.0);
glVertex3f(0.2,-0.1,0.0);
glVertex3f(0.0,0.0,0.0);
glVertex3f(0.2,0.1,0.0);
glEnd();
}

4. void main(int argc, char **argv) {
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DEPTH |
GLUT_DOUBLE | GLUT_RGBA);
glutInitWindowPosition(100,100);
glutInitWindowSize(320,320);
glutCreateWindow("graphics lab");
glutDisplayFunc(renderScene);
glutMainLoop();
}
