GeoJSON to OBJ

A converter from GeoJSON to Wavefront OBJ format.

API

toObj(geojson, stream, options)

Converts the geojson to an OBJ, that is written to the stream.

Note that the geojson must be a Feature or FeatureCollection.

Available options:

• featureBase: function f(feature) that returns the height of a feature's base; by default, a function that always returns 0.
• featureHeight: function f(feature) that returns the height of a feature; by default, a function that returns 10 for polygons and 0.3 for linestrings.
• lineWidth: for line geometries, returns the width of the generated geometry; defaults to 2.
• featureName: a function f(feature) that returns the OBJ group name used for a feature; by default a function that numbers the features
• featureMaterial: a function f(feature) that returns the name of the material for a feature; if undefined, the material is not changed for this feature; see mtllib option below
• coordToPoint a function f(coordinate) that returns the OBJ vertex point (X and Z) for a GeoJSON coordinate, needed to convert from GeoJSON's WGS84 coordinates to a cartesian coordinate; see the findLocalProj method below
• mtllib a string or array of paths that will be added as material libraries to the resulting OBJ
