Module obj 

Wavefront OBJ format import and export.

This module provides conversion between OBJ files and 3MF Model structures.

OBJ Format

The Wavefront OBJ format is a text-based 3D geometry format. This implementation supports a basic subset of the full OBJ specification:

Supported features:

• v - Vertex positions (x, y, z)
• f - Faces (vertex indices)
• Polygon faces (automatically triangulated using fan triangulation)

Ignored features:

• vt - Texture coordinates
• vn - Vertex normals
• g - Group names
• usemtl - Material references
• mtllib - Material library files

Examples

Importing OBJ

use lib3mf_converters::obj::ObjImporter;
use std::fs::File;

let file = File::open("model.obj")?;
let model = ObjImporter::read(file)?;
println!("Imported model with {} build items", model.build.items.len());

Exporting OBJ

use lib3mf_converters::obj::ObjExporter;
use lib3mf_core::model::Model;
use std::fs::File;

let file = File::create("output.obj")?;
ObjExporter::write(&model, file)?;

Structs

ObjExporter

Exports 3MF Model structures to Wavefront OBJ files.

ObjImporter

Imports Wavefront OBJ files into 3MF Model structures.
