Clean up Waterman / Cahill

Open Fil opened this issue 7 years ago • 3 comments

The issue is described here: https://github.com/d3/d3-geo-projection/issues/125

To sum up this would need to:

  • [ ] introduce geoCahill1909 (which would be geoPolyhedralWaterman but with the inferior choice of angles from Cahill's original — and that could be a parameter of course), and be mindful of the face projection used in 1909
  • [ ] create a "true" geoWaterman with Antarctica cut out (see also https://github.com/d3/d3-geo-polygon/issues/11)
  • [ ] obsolete geoPolyhedralWaterman

For the moment I don't see very well how the Antarctica piece is made in Steve Waterman's original — the angles and the parallels in my draft are not the same as in the original.
