Kotlin/JVM port of the popular [three.js](http://threejs.org) 3D library ([r106](https://github.com/mrdoob/three.js/tree/r106)).
Be warned, while the basics works, such as:
* Primitives, Points and TubeGeometry
* All materials and lights
* OrbitControls
* 2D textures
* Raycasting against Mesh
* OBJ, MTL and STL loaders
* Other stuff like mirror, sky and water shaders
a lot of features are still missing and the API can change rapidly.
Right now, this is mostly interesting for developers that want to contribute.
#### API (subject to changes)
##### Kotlin
```kotlin
Window(antialias = 4).use { window ->
val scene = Scene().apply {
setBackground(Color.aliceblue)
}
val camera = PerspectiveCamera(75, window.aspect, 0.1, 1000).apply {
position.z = 5f
}
val renderer = GLRenderer(window.size)
val box = Mesh(BoxGeometry(1f), MeshBasicMaterial().apply {
color.set(0x00ff00)
})
scene.add(box)
val clock = Clock()
val controls = OrbitControls(camera, window)
window.animate {
val dt = clock.getDelta()
box.rotation.x += 1f * dt
box.rotation.y += 1f * dt
renderer.render(scene, camera)
}
}
```
##### Java
```java
public class JavaExample {
public static void main(String[] args) {
try (Window window = new Window()) {
Scene scene = new Scene();
PerspectiveCamera camera = new PerspectiveCamera();
camera.getPosition().z = 5;
GLRenderer renderer = new GLRenderer(window.getSize());
BoxBufferGeometry boxBufferGeometry = new BoxBufferGeometry();
MeshPhongMaterial boxMaterial = new MeshPhongMaterial();
boxMaterial.getColor().set(Color.getRoyalblue());
Mesh box = new Mesh(boxBufferGeometry, boxMaterial);
scene.add(box);
MeshBasicMaterial wireframeMaterial = new MeshBasicMaterial();
wireframeMaterial.getColor().set(0x000000);
wireframeMaterial.setWireframe(true);
Mesh wireframe = new Mesh(box.getGeometry().clone(), wireframeMaterial);
scene.add(wireframe);
AmbientLight light = new AmbientLight();
scene.add(light);
OrbitControls orbitControls = new OrbitControls(camera, window);
window.animate(() -> {
renderer.render(scene, camera);
});
}
}
}
```
