Overview
Installation
@oneisland/graphics is available through the npm registry:
$ npm install @onesland/graphicsUsage
Creating a simple animation of a rotating cube:
cube.js
// Define the vertices for the cube
const vertices = [
[-1, -1, 1],
[ 1, -1, 1],
[ 1, -1, -1],
[-1, -1, -1],
[-1, 1, 1],
[ 1, 1, 1],
[ 1, 1, -1],
[-1, 1, -1]
];
// Define the faces for the cube
const faces = [
[2, 3, 0],
[0, 1, 2],
[7, 3, 0],
[0, 4, 7],
[4, 0, 1],
[1, 5, 4],
[6, 2, 3],
[3, 7, 6],
[5, 1, 2],
[2, 6, 5],
[7, 4, 5],
[5, 6, 7]
];engine.js
// Create the engine
const engine = new Engine('#engine', async({ canvas, context }) => {
// Create a scene
const scene = new Scene('scene', { canvas, context });
// Create a cube
const cube = new Mesh('cube', { vertices, faces, scene });
// Create an animation to rotate the mesh
const animation = new Animation('rotate', (mesh, delta) => mesh.rotate());
// Add the animation to the cube
cube.addAnimation(animation);
// Return the scene
return scene;
});
// Show the frames per second
engine.showFPS();index.html
