This deserializer converts raw OBJ formatted data (files) to JSCAD scripts or geometries.

NOTE: At this time, only ASCII OBJ files are supported. BINARY OBJ files are not supported.

This deserializer converts only what is supported by JSCAD libraries. Full document conversion is NOT supported, so don't even try. However, conversion of the following OBJ commands are possible:

OBJ Command JSCAD Geometry Notes
V to geom3 vertices of polygons
F to geom3 indexes to polygon vertices
G to geom3 grouping of V and F to create polygons and geometry

Also, if the 'USEMTL' (material) matches the name of a CSS3 color then the color is applied to the geometry.

const rawData = fs.readFileSync('PATH/TO/file.obj')
const geometries = objDeserializer.deserialize(rawData, 'file.obj', {output: 'geometry'})
