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.
