在我的场景中,我加载了一个 .gltf 模型,它渲染得很好。它有一个 .png 纹理,渲染在 3D 模型的表面上。是否可以通过编程方式交换纹理?我正在使用 aframe (a-asset-item 和 a-entity 来加载 gltf 资产)
Once you’ve loaded a model in A-Frame or three.js, it doesn’t matter much what format it was before1. For A-Frame, you can use JS to modify the model after it loads.
var tex = new THREE.TextureLoader().load('diffuse.png');
tex.flipY = false; // for glTF models.
el.addEventListener('model-loaded', function (e {
e.detail.model.traverse(function(node) {
if (node.isMesh) node.material.map = tex;
});
});
请参阅文档三.Mesh标准材质了解需要编辑哪些属性,尽管这可能会根据您加载的模型而有所不同。
1 One exception is the tex.flipY=false
setting above — you'll (probably) only need that for glTF, where the UVs have a different orientation than the three.js default.
