使用Threejs在球体上的每个元素上添加几个图像

标签: javascript three.js

这是我所说的球形结构 - Clickhere

在这个球体网格中,我希望在每个元素上添加几个图像。 就像,使用这个代码我们可以转换成各种形状,如网格,平面等。无论形状如何,我想在网格中的每个元素上添加不同的图像。

我真的对此没有任何线索。你能帮帮我吗? 这是我从three.js webstite中复制和粘贴的代码:



template<int... myints>
struct A
{}

template<int... myints, class traits = A<myints...>>
struct B
{}
