threeify is a Typescript 3D library loosely based on three.js.
In Development, Not Yet Ready for Use of Any Kind
This library is currently in alpha and in midst of significant development. It may not even compile properly. You have been warned.
This code creates a scene, a camera, and a geometric cube, and it adds the cube to the scene. It then creates a WebGL
renderer context for the scene and camera, and it adds that viewport to the document.body
element. Finally, it animates the cube within the scene for the camera.
import { box } from "@threeify/geometry/primitives/Box";
import { MaterialOutputs } from "@threeify/materials/MaterialOutputs";
import { PhysicalMaterial } from "@threeify/materials/PhysicalMaterial";
import { PerspectiveCamera } from "@threeify/nodes/cameras/PerspectiveCamera";
import { Mesh } from "@threeify/nodes/Mesh";
import { Node } from "@threeify/nodes/Node";
import { RenderingContext } from "@threeify/renderers/webgl2";
const camera = new PerspectiveCamera(70, 0.01, 10);
camera.position.x = 1;
const geometry = box(0.2, 0.2, 0.2);
const material = new PhysicalMaterial();
material.outputs = MaterialOutputs.Normal;
const mesh = new Mesh(geometry, material);
const scene = new Node();
scene.children.add(mesh);
const context = new RenderingContext();
const canvasFramebuffer = context.canvasFramebuffer;
document.body.appendChild(canvasFramebuffer.canvas);
function animate(): void {
requestAnimationFrame(animate);
mesh.rotation.x += 0.01;
mesh.rotation.y += 0.02;
mesh.dirty();
canvasFramebuffer.render(scene, camera, true);
}
animate();
To run:
- Check out the git repository
- Install node.js & npm as appropriate for your platform.
- Run npm install to install all the required node modules from package.json
yarn
- To run the automatic typescript builder and dev server go:
yarn dev
Then open a web server to the address displayed in the console. Usually this will be http://localhost:8000.
If you have docker and docker-compose available do:
docker-compose up -d
threeify supports the theia-ide so you can start coding immediately. theia-ide is available at http://localhost:3000. Perform step 3 and 4 in the theia-ide terminal.
This project exists thanks to all the people who contribute.
