# melo
melo is mesh loader for OBJ, glTF2 and PLY, also includes a `Cinder` based mesh viewer on Windows and macOS.
# Features
- Support Windows and macOS
- Can be used outside of Cinder
- Loading OBJ meshes through [syoyo/tinyobjloader](https://github.com/syoyo/tinyobjloader)
- Loading glTF2 meshes through [syoyo/tinygltf](https://github.com/syoyo/tinygltf)
- PBR rendering w/ modified shaders from [KhronosGroup/glTF-WebGL-PBR](https://github.com/KhronosGroup/glTF-WebGL-PBR/tree/master/shaders)
# TODO
- Implement skinning animation
- Implement morph animation
- Support Linux / Android / iOS
- Support Sketchfab download API
- FrameGraph
# To build `samples/MeshViewer`, you need:
* [Cinder](https://github.com/cinder/Cinder)
* [Cinder-VNM](https://github.com/jing-interactive/Cinder-VNM)
The folder structure should appear like this:
```
