OpenGL - Change Torus color into Red instead Grey Color

Hi,

Kindly let me know, How do I change the torus color into Red instead Grey color and what command lines are required to do the same.

Thank you

Here are codes:

#include #include static int spin=0; void init(void){ glClearColor(0.0, 0.0, 0.0, 0.0); glShadeModel(GL_SMOOTH); glEnable(GL_LIGHTING); glEnable(GL_LIGHT0); glEnable(GL_DEPTH_TEST);} void display(void){ GLfloat position[] = {0.0, 0.0, 1.5, 1.0}; glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glPushMatrix(); gluLookAt(0.0, 0.0, 5.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0); glPushMatrix(); glRotated((GLdouble) spin, 1.0, 0.0, 0.0); glLightfv(GL_LIGHT0, GL_POSITION, position); glTranslated(0.0, 0.0, 1.5); glDisable(GL_LIGHTING); glutWireCube(0.0); glEnable(GL_LIGHTING); glPopMatrix(); glutSolidTorus(0.275, 0.85, 8, 5); glPopMatrix(); glFlush();} void reshape (int w, int h){ glViewport(0,0, (GLsizei) w, (GLsizei) h); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective(40.0, (GLfloat) w / (GLfloat) h, 1.0, 20.0); glMatrixMode(GL_MODELVIEW); glLoadIdentity();} void mouse(int button, int state, int x, int y){ switch(button) { case GLUT_LEFT_BUTTON: if(state == GLUT_DOWN) { glEnable(GL_LIGHTING); spin = (spin + 30) % 360; glutPostRedisplay(); } break; default: break; }} void keyboard(unsigned char key, int x, int y){ switch(key) { case 27: exit(0); break; }} int main(int argc, char** argv){ glutInit(&argc, argv); glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB | GLUT_DEPTH); glutInitWindowSize(500,500); glutInitWindowPosition(100,100); glutCreateWindow("My Torus with Mouse Click"); glutDisplayFunc(display); init(); glutReshapeFunc(reshape); glutMouseFunc(mouse); glutKeyboardFunc(keyboard); glutMainLoop(); return 0;}
