以上三个动图分别是加载DDS、PVR、TGA格式的纹理的效果图
2. 实现要点
与上一片文章基本相同，不同的地方只是使用不同的纹理加载器，加载的纹理图片不同
2.1 加载DDS格式纹理
createMesh(geom) {const publicPath = process.env.BASE_URL //获取环境变量URLconst loader = new DDSLoader() //创建纹理加载器const texture = loader.load(`${publicPath}textures/seafloor.dds`) //加载纹理const mat = new THREE.MeshPhongMaterial() // 加载的纹理作为纹理贴图创建材质mat.map = textureconst mesh = new THREE.Mesh(geom, mat) //创建网格对象return mesh}
2.2 加载PVR格式纹理
createMesh(geom) {const publicPath = process.env.BASE_URL //获取环境变量URLconst loader = new PVRLoader() //创建纹理加载器const texture = loader.load(`${publicPath}textures/tex_base.pvr`) //加载纹理const mat = new THREE.MeshPhongMaterial() // 加载的纹理作为纹理贴图创建材质mat.map = textureconst mesh = new THREE.Mesh(geom, mat) //创建网格对象return mesh}
2.3 加载TGA格式纹理
createMesh(geom) {const publicPath = process.env.BASE_URL //获取环境变量URLconst loader = new TGALoader() //创建纹理加载器const texture = loader.load(`${publicPath}textures/crate_color8.tga`) //加载纹理const mat = new THREE.MeshPhongMaterial() // 加载的纹理作为纹理贴图创建材质mat.map = textureconst mesh = new THREE.Mesh(geom, mat) //创建网格对象return mesh}
3. demo代码
三个示例的代码基本雷同，不同于使用不同的加载器和加载不同的纹理，上一步中有说明，这里只贴出加载DDS格式纹理的代码
