[![Build Status](https://travis-ci.org/bwasty/mikktspace-rs.svg?branch=master)](https://travis-ci.org/gltf-rs/mikktspace)

Bindings to the [Mikkelsen Tangent Space Algorithm](https://wiki.blender.org/index.php/Dev:Shading/Tangent_Space_Normal_Maps) reference implementation.

## Examples

### generate

Demonstrates generating tangents for a cube with 4 triangular faces per side.

```sh
cargo run --example generate
```

There is also an equivalent C example to check the correctness of the Rust bindings.

```sh
cd examples
cmake ../libmikktspace
make
cc generate.c libmikktspace.a -I../libmikktspace -lm -o generate
./generate
```
