Create a new placeholder tensor inside this pipeline. Different from a local tensor, a placeholder tensor has no local memory allocated in the pipeline's scope; on the contrary, the placeholder must refer to a compatible global tensor when the pipeline is submitted for execution.

Create a new placeholder tensor inside this pipeline with guarantee compatibility with the a GlobalTensor, i.e., the newly created placeholder share the same configuration with the GlobalTensor. Note: a placeholder tensor has no local memory allocated in the pipeline's scope; on the contrary, the placeholder must refer to a compatible global tensor when the pipeline is submitted for execution.

Create an SpatialML scene from a glTF file already loaded into SharedMemory. Similar to SpatialMLSession.newSceneFromGLTF but that one creates a global scene graph handle, so that multiple pipelines can share, whereas this method creates one scene graph local to the pipeline only.
