OBJRuntime

OBJRuntime is a .NET library for loading and processing Wavefront OBJ files. It supports parsing vertex data, normals, texture coordinates, materials, and more. Designed for use with .NET 8 and C# 12.0, this library enables easy integration of 3D models into your applications.

Features

• Load OBJ files with:
  • Vertex positions
  • Normals
  • Texture coordinates
  • Vertex colors and weights
• Full support for materials defined in MTL files
• Handle multiple texture types: diffuse, specular, normal maps, etc.
• PBR (Physically Based Rendering) material properties support

Usage

Integrating OBJRuntime is simple. Load and instantiate your model as follows:

var model = await OBJRuntime.Instance.Read("Models/orc/orc.obj");
var assetsService = Application.Current.Container.Resolve<AssetsService>();
var entity = model.InstantiateModelHierarchy(assetsService);
this.Managers.EntityManager.Add(entity);

Tests

The project includes a set of unit tests to ensure the correctness of the OBJ loader. The tests are located in the OBJTests project.
