Class TOrientationInterpolatorNode

Return rotation (as axis+angle) at given time (key). Makes a warning and returns zero if FdKey is empty.

Create node fields and events.

Node type name in VRML/X3D, for this class. Normal VRML/X3D node classes should override this to return something non-empty, and then X3DType automatically will return the same value.

Empty for classes that don't have a hardcoded VRML/X3D node name, like a special TX3DUnknownNode. Such special classes should override then X3DType to return actual non-empty name there.

You usually should call X3DType. The only use of this method is that it works on classes (it's "class function"), without needing at actual instance.

Internal wrapper for property KeyValue. This wrapper API may change, we advise to access simpler KeyValue instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

Internal wrapper for property KeyValueQuaternions. This wrapper API may change, we advise to access simpler KeyValueQuaternions instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

When True, key values are provided as unit quaternions. By default (when False) they have to be axis angle rotations. This allows extra optimization in case your input data is in quaternions, which is true in case of glTF. It is then most efficient to just put quternions in TOrientationInterpolatorNode.FdKeyValue and set this to True. Otherwise, you would 1. needlessly convert quaternion -> axisangle when reading glTF file, 2. needlessly convert axisangle -> quaternion as a first step of SLerp.
