ClayGL

ClayGL is a type friendly WebGL graphic library for building scalable Web3D applications.

It's easy to use, configurable for high-quality graphics. Benefit from the modularity and tree shaking, it can be scaled down to 22k(gzipped) for a basic 3D application.

Projects

Quick Start

Create a rotating cube

<!DOCTYPE html>
<html lang="en">
  <head>
    <script src="lib/claygl.js"></script>
  </head>
  <body>
    <canvas id="main"></canvas>
    <script>
      const app = new clay.App3D('#main', {
        width: window.innerWidth,
        height: window.innerHeight
      });
      // Create camera
      const camera = app.createCamera([0, 2, 5], [0, 0, 0]);

      // Create a RED cube
      const cube = app.createCube({
        color: '#f00'
      });

      // Create light
      const mainLight = app.createDirectionalLight([-1, -1, -1]);

      app.loop((frameTime) => {
        cube.rotation.rotateY(frameTime / 1000);
      });
    </script>
  </body>
</html>

Minimum bundle example

This example is about 22k(gzipped) after bundled by webpack 4.0. It draws a triangle on the screen.

import { Renderer, GeometryBase, Shader, Material, glsl } from 'claygl';

const vs = new Shader.Vertex({
  attributes: {
    position: Shader.attribute('vec3', 'POSITION')
  },
  main: glsl`
void main() {
  gl_Position = vec4(position, 1.0);
}`
});
const fs = new Shader.Fragment({
  uniforms: {
    color: Shader.uniform('rgb', 'red')
  },
  main: glsl`
void main() {
  out_color = vec4(color, 1.0);
}
`
});

const renderer = new Renderer({
  canvas: document.getElementById('main')
});
renderer.resize(400, 400);

const geometry = new GeometryBase();
const positionAttrib = geometry.createAttribute('position', 'float', 3);
// Add triangle vertices to position attribute.
positionAttrib.fromArray([
  [-0.5, -0.5, 0],
  [0.5, -0.5, 0],
  [0, 0.5, 0]
]);

const material = new Material(new Shader(vs, fs));
// 'color' have correct type here.
material.set('color', 'red');

renderer.renderPass([{ geometry, material }]);
