## Interface R2InstanceBatchedType

- All Superinterfaces:
    R2InstanceType
  All Known Subinterfaces:
    R2InstanceBatchedDynamicType
  All Known Implementing Classes:
    R2InstanceBatchedDynamic

      public interface R2InstanceBatchedType
      extends R2InstanceType

  The type of batched instances.

  A batch consists of a set of one or more vertex buffers containing mesh data, and a vertex buffer containing a set of transforms - one per rendered object.

  The primary use case for batched instances is rendering a lot of copies of the same mesh in a single draw call.
