SketchUp 导出带有纹理的 obj - 如何 [英] SketchUp export obj with textures - how

问题描述

Windows 7(64 位)，SketchUp Make 13.0.4812.

Windows 7 (64bit), SketchUp Make 13.0.4812.

目标:将 SketchUp .skp 模型转换为 .obj 并使用 Three.js 加载到 WebGL.

Goal: convert SketchUp .skp model to .obj and load to WebGL using three.js.

问题: Sketchup 导出模型到.obj 带有外部纹理，这些纹理没有被three.js 加载.

Problem: sketchup exports model to .obj with external textures, and these textures are not loaded by three.js.

问题:是否可以将 SketchUp 模型保存为一个带有纹理的 .obj 文件?

Question: is it possible to save SketchUp model as one .obj file with textures?

推荐答案

不，.obj 是一种简单的文本格式.您不能在 .obj 中存储纹理.这是一个示例，说明如何从单独的 .jpg 文件加载纹理.

No, .obj is a simple text format. You can't store textures in .obj. Here is an example on how to load the texture from a separate .jpg file.

我复制了重要的部分:

// texture
var manager = new THREE.LoadingManager();
manager.onProgress = function ( item, loaded, total ) {
  console.log( item, loaded, total );
};
var texture = new THREE.Texture();
var loader = new THREE.ImageLoader( manager );
loader.load( 'textures/ash_uvgrid01.jpg', function ( image ) {
  texture.image = image;
  texture.needsUpdate = true;
} );

// model
var loader = new THREE.OBJLoader( manager );
loader.load( 'obj/male02/male02.obj', function ( object ) {
  object.traverse( function ( child ) {
    if ( child instanceof THREE.Mesh ) {
      child.material.map = texture;
    }
    scene.add( object );
  });
});
