3.5.20 Stereo image

One can easily create stereo image in MathGL. Stereo image can be produced by making two subplots with slightly different rotation angles. The corresponding code looks like this:

int sample(mglGraph *gr)
{
  mglData a;  mgls_prepare2d(&a);
  gr->Light(true);

  gr->SubPlot(2,1,0); gr->Rotate(50,60+1);
  gr->Box();  gr->Surf(a);

  gr->SubPlot(2,1,1); gr->Rotate(50,60-1);
  gr->Box();  gr->Surf(a);
  return 0;
}
