Hi,
Kindly let me know, how do I change torus color into Red instead Grey color and what command lines are required to do the same.
Thank you
Here are codes
#include <gl/glut.h>
#include <stdlib.h>
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;
}
