3.5.5 Adding fog

MathGL can add a fog to the image. Its switching on is rather simple – just use fog function. There is the only feature – fog is applied for whole image. Not to particular subplot. The sample code is:

int sample(mglGraph *gr)
{
  mglData a;  mgls_prepare2d(&a);
  gr->Title("Fog sample");
  gr->Light(true);  gr->Rotate(50,60);  gr->Fog(1); gr->Box();
  gr->Surf(a);  gr->Cont(a,"y");
  return 0;
}
