The makeIdentity command is a quick way to reset the selected transform and all of its children down to the shape level by the identity transformation. You can also specify which of transform, rotate or scale is applied down from the selected transform. The identity transformation means: translate = 0, 0, 0rotate = 0, 0, 0scale = 1, 1, 1shear = 1, 1, 1If a transform is a joint, then the translateattribute may not be 0, but will be used to position the joints so that they preserve their world space positions. The translate flag doesn’t apply to joints, since joints must preserve their world space positions. Only the rotate and scale flags are meaningful when applied to joints. If the -a/apply flag is true, then the transforms that are reset are accumulated and applied to the all shapes below the modified transforms, so that the shapes will not move. The pivot positions are recalculated so that they also will not move in world space. If this flag is false, then the transformations are reset to identity, without any changes to preserve position.
If this flag is true, the accumulated transforms are applied to the shape after the transforms are made identity, such that the world space positions of the transforms pivots are preserved, and the shapes do not move. The default is false.
If this flag is set, the joint orient on joints will be reset to align with worldspace.
If this flag is set to 1, the normals on polygonal objects will be frozen. This flag is valid only when the -apply flag is on. If this flag is set to 2, the normals on polygonal objects will be frozen only if its a non-rigid transformation matrix. ie, a transformation that does not contain shear, skew or non-proportional scaling. The default behaviour is not to freeze normals. Flag can have multiple arguments, passed either as a tuple or a list.
If this flag is true, only the rotation is applied to the shape. The rotation will be changed to 0, 0, 0. If neither translate nor rotate nor scale flags are specified, then all (t, r, s) are applied.
If this flag is true, only the scale is applied to the shape. The scale factor will be changed to 1, 1, 1. If neither translate nor rotate nor scale flags are specified, then all (t, r, s) are applied.
If this flag is true, only the translation is applied to the shape. The translation will be changed to 0, 0, 0. If neither translate nor rotate nor scale flags are specified, then all (t, r, s) are applied. (Note: the translate flag is not meaningful when applied to joints, since joints are made to preserve their world space position. This flag will have no effect on joints.)
