2.7.1 Surf3 sample

Surf3 is one of most suitable (for my opinion) functions to visualize 3D data. It draw the isosurface(s) – surface(s) of constant amplitude (3D analogue of contour lines). You can draw wired isosurfaces if specify ‘#’ style. The sample code is:

int sample(mglGraph *gr)
{
  mglData c;  mgls_prepare3d(&c);
  gr->Title("Surf3 plot");  gr->Rotate(50,60);
  gr->Light(true);  gr->Alpha(true);
  gr->Box();  gr->Surf3(c);
  return 0;
}
