Сonvert geographic points considering antimeridian and pole

[Do|While|For|Each]

You provided a great opportunity to render geographic data given the antimeridian and pole using a geoPath:

const projection = geoMercator()

  .rotate([70, 0, 0])

  .fitWidth(side, {type: 'Sphere'})
;

const path = geoPath(projection, context);

context.beginPath();

path(land);
 // <--- pass GeoJSON

context.fillStyle = 'black';

context.fill();

Can you please tell me if it is possible to do the following:

1. I have geographic data (GeoJSON, just an array of geographic points, etc.)
2. I pass this data to some d3 function
3. and as a result I get the same geographical data, only taking into account the antimeridian and the pole for the corresponding projection.

The fact is that before drawing on the canvas, I still need to transform the point from the projection in a tricky way. And for me the problem is that geoPath immediately draws on the canvas and I can’t give it the transformation I need from projection -> to view (in the form of a matrix [a, b, c, d, e, f]).
