Features
---

- **Cross-Platform** - Runs on Windows, macOS, Linux, and Android.
- **Cross-Device** - Supports Vive/Index, Oculus Rift/Quest, Windows MR, and has a VR simulator.
- **Beginner-friendly** - Simple VR scenes can be created in just a few lines of Lua.
- **Fast** - Written in C11 and scripted with LuaJIT, includes optimized single-pass stereo rendering.
- **Asset Import** - Supports 3D models (glTF, OBJ), skeletal animation, HDR textures, cubemaps, fonts, etc.
- **Spatialized Audio** - Audio is automatically spatialized using HRTFs.
- **Vector Library** - Efficient first-class support for 3D vectors, quaternions, and matrices.
- **3D Rigid Body Physics** - Including 7 collider shapes, triangle mesh colliders, and 6 joint types.
- **Compute Shaders** - For high performance GPU tasks, like particles.

Getting Started
---

It's really easy to get started making things with LÖVR.  Grab a copy of the executable from <https://lovr.org/downloads>,
then write a `main.lua` script and drag it onto the executable.  Here are some example projects to try:

#### Hello World

```lua
function lovr.draw(pass)
  pass:text('Hello World!', 0, 1.7, -3, .5)
end
```

#### Spinning Cube

```lua
function lovr.draw(pass)
  pass:cube(0, 1.7, -1, .5, lovr.timer.getTime())
end
```

#### Hand Tracking

```lua
function lovr.draw(pass)
  for _, hand in ipairs(lovr.headset.getHands()) do
    pass:sphere(vec3(lovr.headset.getPosition(hand)), .1)
  end
end
```

#### 3D Models

```lua
function lovr.load()
  model = lovr.graphics.newModel('model.gltf')
end

function lovr.draw(pass)
  pass:draw(model, x, y, z)
end
```

More examples are on the [docs page](https://lovr.org/docs/Intro/Hello_World).

Building
---

You can build LÖVR from source using CMake.  Here are the steps using the command line:

```console
mkdir build
cd build
cmake ..
cmake --build .
```

See the [Compiling Guide](https://lovr.org/docs/Compiling) for more info.

Testing
---

Tests can be found in the `test/lovr` directory.

You can run all of LÖVR tests from the command line with the following:

```console
./build/bin/lovr test
```

To run tests for a single module, pass the name of the module as an argument
(e.g. this runs the tests for the data module):

```console
./build/bin/lovr test data
```
