I have a GeoJson polygon I am trying to draw in a 3d scene using d3 and three.js

I have done this before when the polygon was represented in lat, lng coordinates, but in my case the coordinate system is just integers between -10 and 10 for both x and y.

var path = d3.geo.path().projection(d3.geo.equirectangular().center([0,0]))
var contour = transformSVGPath(path(geoJSONObject));

However if I add this object to my scene, it is translated far away from its center (0, 0)

What am I doing wrong?

It turns out that when applying d3 projections, there is a default translation of [480, 250].

This can be overridden by setting the translation manually:

var projection = d3.geo.equirectangular();
