Return True when at least one asset is prepared and no errors occurred.

Return a schema-annotated action copy without mutating legacy data.

Return a schema-annotated robot-state copy without editing a trajectory.

Normalize a quaternion in any component order.

Preprocess an input GLB and return prepared asset metadata.

Propagate one object's pose through another object's rigid motion. Returns: (new_pos2, new_quat2_wxyz)

Multiply two quaternions in ``[w, x, y, z]`` format. Prefer ``scipy.spatial.transform.Rotation`` for new code; this helper is kept for c

Register a named callable for use with ``CustomFilter``. The callable receives ``(uid, unified_metadata)`` and returns bool.

Append a filter to the chain. Returns self for chaining. Example: client.register_filter(Step1xQualityFilter())

Reset derivative history at the start of an episode.

Restore a legacy MimicGen action target onto this articulation. MimicGen steps store measured robot state in ``step["robot"]`` and a

Restore legacy MimicGen robot state onto the current articulation. Older Robotiq recordings store a full 13-DoF joint vector in ``rob

Rotate a quaternion by a given angle around the world Z axis. Args: quat_wxyz: Quaternion in ``[w, x, y, z]`` order. angle_d

Rotate a vector with a ``[w, x, y, z]`` quaternion.

Retrieve Objaverse UIDs matching a single text prompt. The optional ``filters`` field accepts a serialized ``FilterChain`` (use ``Filter

Retrieve UIDs for multiple prompts in a single call. All prompts share the same FilterChain and ``top_k`` setting.

Retrieve UIDs for multiple prompts in a single server round-trip. Args: prompts: List of text prompts. top_k

Interpolate between two poses with linear position blending and SLERP. ``alpha=0`` returns the first pose and ``alpha=1`` returns the second

Remove all filters of the given type string (e.g. ``"license"``). Returns self for chaining.
