剔除批次上下文。
指定执行剔除所需的数据。另请参阅：OnPerformCulling。
| cullingFlags | Additional culling information for the current context. |
| cullingLayerMask | The cullingLayerMask value of the object from which the culling is invoked. The draw command is discarded by the internal culling if the expression (1 << layer) & cullingLayerMask is false. Using this field is optional, use it for performance or other optimization purposes. |
| cullingPlanes | 要对其剔除的平面。 |
| cullingSplits | The array of CullingSplit structs. |
| localToWorldMatrix | Local to world matrix. |
| lodParameters | 另请参阅：LODParameters。 |
| projectionType | The projection of the view from which the culling is invoked. Usage example: take different culling paths for orthographic vs perspective views. |
| receiverPlaneCount | The number of receiver planes. |
| receiverPlaneOffset | The index of the first receiver plane in the BatchCullingContext.cullingPlanes array. |
| sceneCullingMask | Use this bit mask to discard the draw commands in a particular context. A draw command is not discarded if the expression (1 << layer) & sceneCullingMask is true. This field is typically used when rendering Editor previews. |
| viewID | The ID of the object from which the culling is invoked. Usage example: store culling-related data for each object. |
| viewType | The type of the view from which the culling is invoked. Usage examples: skip culling, take different culling paths depending on the view type, etc. |
