indices | 要填充的索引的列表。 |
submesh | 子网格索引。请参阅 subMeshCount。 |
applyBaseVertex | true(默认值)会向返回的索引应用基顶点偏移。 |
获取指定子网格的索引列表。
返回列表中的每个整数都是顶点索引,这用作网格顶点数组的偏移。请参阅 vertices 和 GetVertices。索引的布局取决于子网格的 MeshTopology。例如,三角形网格返回的索引是三的倍数。
子网格表示使用单个 Material 渲染的三角形(或具有不同 MeshTopology 的索引)的列表。当网格与具有多个材质的 Renderer 一起使用时,应确保每个材质有一个子网格。
如果要控制索引缓冲区的生命周期并且需要避免在每次访问时都分配新数组,请使用 List<int>
参数调用方法重载。
另请参阅:subMeshCount、GetTopology、MeshTopology 枚举。
