+
+[![Build status](https://ci.appveyor.com/api/projects/status/i5ku97hf0r0quti3?svg=true)](https://ci.appveyor.com/project/syoyo/tinygltfloader)
+
+## Features
+
+* Portable C++. C++-98 with STL dependency only.
+* Moderate parsing time and memory consumption.
+* glTF specification v1.0.0
+* Buffers
+  * [x] Parse BASE64 encoded embedded buffer fata(DataURI).
+  * [x] Load `.bin` file.
+* Image(Using stb_image)
+  * [x] Parse BASE64 encoded embedded image fata(DataURI).
+  * [x] Load external image file.
+  * [x] PNG(8bit only)
+  * [x] JPEG(8bit only)
+  * [x] BMP
+  * [x] GIF
+
+## Limitation
+
+Currently, TinyGLTFLoader only loads nodes and geometry(mesh/buffer) data.
+
+## Examples
+
+* [glview](examples/glview) : Simple glTF geometry viewer.
+
+## TODOs
+
+* [ ] Support multiple scenes in `.gltf`
+* [ ] Parse `animation`, `program`, `sampler`, `shader`, `technique`, `texture`
+* [ ] Compression/decompression(Open3DGC, etc)
+* [ ] Support `extensions` and `extras` property
+* [ ] HDR image
+* [ ] Binary glTF.
