A geometry batch is a subcomponent of a mesh, representing a single piece of homogeneous geometry that can be submitted to the GPU in a single draw call. It contains an indexed triangle list (using a single material) where all vertices share the same set of data channels. Vertices are made unique if there are differences in any of their data channels. Coordinates that require unique vertices on either side of a join create unique vertices.
