Question

在加载Collada(dae)模型时如何在THREE.js中设置材料？

我有以下代码:

    new THREE.ColladaLoader().load('models/cylinder.dae',
function(collada) {
    var model = collada.scene;
    model.scale.set(10.0, 10.0, 10.0);

    // attempt to set a material - doesn't work...
    collada.dae.materials[0] = new THREE.MeshBasicMaterial( { color: 0xff0000, wireframe: true } );

    scene.add(model);
});

谢谢你的帮助.

Answer 1

var loader = new THREE.ColladaLoader();
loader.options.convertUpAxis = true;
loader.load( './models/cylinder.dae',function colladaReady( collada ) {

model = collada.scene;
model_geometry = collada.scene.children[ 0 ].geometry;
model_material = collada.scene.children[ 0 ].material;

model.scale.set(10.0, 10.0, 10.0);
model.updateMatrix();
});

如果你将model_material作为'undefined',那么看看collada对象

console.log(collada);

有时孩子里面有孩子,所以你可能不得不这样做:

model_material = collada.scene.children[ 0 ].children[ 0 ].material;

看看collada模型,然后相应地修改.
