描述
|
||
----
|
||
|
||
生成轴对齐盒 :ref:`PrimitiveMesh<class_PrimitiveMesh>`\ 。
|
||
|
||
这个盒子的 UV 布局是以 3×2 的方式排列的，允许单独对每个面进行贴图。要在所有的面上应用相同的纹理，请将材质的 UV 属性改为 ``Vector3(3, 2, 1)``\ 。这样做等价于在顶点着色器中添加 ``UV *= vec2(3.0, 2.0)``\ 。
|
||
|
||
\ **注意：**\ 当使用很大且有纹理的 **BoxMesh** 时（例如作为地板），你可能会发现 UV 偶尔抖动的问题，这取决于相机的角度。要解决此问题，请增加 :ref:`subdivide_depth<class_BoxMesh_property_subdivide_depth>`\ 、\ :ref:`subdivide_height<class_BoxMesh_property_subdivide_height>` 和 :ref:`subdivide_width<class_BoxMesh_property_subdivide_width>`\ ，直到你不再注意到 UV 抖动。
