nativescript-three

安装

npm i three nativescript-three

用法

import TNSTHREE from 'nativescript-three';

创建渲染器

TNSTHREE.Renderer({ gl: WebGLRenderingContext, width: number, height: number, pixelRatio: number, ...extras })

给定一个来自 TNSCanvas 的 gl (上下文)，返回一个 THREE.WebGLRenderer，它将绘制到其中。

import { Renderer } from 'nativescript-three';

var camera, scene, renderer;
var geometry, material, mesh;

canvas; // TNSCanvas instance
init();
animate();

function init() {
  const gl = canvas.getContext('webgl');
  // We have access to window.innerWidth / window.innerHeight but we want the current view size
  const { drawingBufferWidth: width, drawingBufferHeight: height } = gl;
  camera = new THREE.PerspectiveCamera(70, width / height, 0.01, 10);
  camera.position.z = 1;

  scene = new THREE.Scene();

  geometry = new THREE.BoxGeometry(0.2, 0.2, 0.2);
  material = new THREE.MeshNormalMaterial();

  mesh = new THREE.Mesh(geometry, material);
  scene.add(mesh);

  renderer = new TNSTHREE.Renderer({ gl });
  renderer.setSize(width, height);
}

function animate() {
  requestAnimationFrame(animate);

  mesh.rotation.x += 0.01;
  mesh.rotation.y += 0.02;

  renderer.render(scene, camera);

  canvas.flush(); // very important, call when you need to render to screen.
}
