3D-Engine

a 3d rendering library for browser environments written in typescript from scratch (no webgl).

Getting started

Installation

Download the source files or install via npm

npm install https://github.com/Elazarbsh/3D-Engine/releases/download/v1.0.0/ts-3d-engine-1.0.0.tgz

Usage

import { Model, Vec3, Camera, Light, Renderer, Scene, RGBA, Material, TextureLoader, ModelLoader } from "ts-3d-engine";

(async () => {
  const canvas = document.getElementById("canvas") as HTMLCanvasElement;

  const renderer: Renderer = new Renderer(canvas);

  const cam: Camera = new Camera();
  cam.position = new Vec3(0, 1, -5);

  const light: Light = new Light();
  light.direction = new Vec3(0, 0, 1);

  const scene: Scene = new Scene(light);

  const texture = await TextureLoader.loadTextureFromImage("texture.png");

  const material = new Material();
  material.color = new RGBA(255, 255, 255);
  material.wireframe = true;
  material.wireframeWidth = 2;
  material.texture = texture;

  const mesh: Model = await ModelLoader.loadFromObjectFile('model.obj');
  mesh.material = material;
  mesh.translation = new Vec3(0, 0, 0);

  scene.addModel(mesh);

  function animate(timeElapsed: number) {
    const yRotation = timeElapsed * 0.2;
    mesh.rotation = new Vec3(0, yRotation, 0);
    renderer.render(scene, cam);
  }

  const intervalInMilliseconds = 30;
  let start = new Date();
  let end = new Date();
  let timeElapsed = 0;

  setInterval(() => {
    timeElapsed = ((end.getTime() - start.getTime()) / 1000);
    animate(timeElapsed);
    end = new Date();
  },
    intervalInMilliseconds);
})();
