| indices | 要从中进行复制的索引的数组。该数组的长度必须与分配的索引数量一致。 |
Fills the values of the allocated indices with values copied directly from an array. Each 3 consecutive indices form a single triangle.
When this method is called, it is not possible to use SetNextIndex to fill the indices.
| indices | The slice of indices to copy from. The length of the slice must match the allocated index count. |
Fills the values of the allocated indices with values copied directly from a slice. Each 3 consecutive indices form a single triangle. When this method is called, it is not possible to use SetNextIndex to fill the indices.
