Returns

Created splines.

HairGuides.ToLocal(self)

Changes all the points for the guides into a local coordinate system.

HairGuides.ToWorld(self)

Changes all the points for the guides into the world coordinate system.

HairGuides.DisplaceRoots(self)

Used when HNs have affected the guide roots.

Call HairGuides.DisplaceRoots() and it will ensure they are in the correct displaced state for HNs, HairGuides.UndisplaceRoots() will make sure they are not.

Generally not needed if using ToInitial(), as the initial state is undisplaced.

Parameters

• index (int) – Guide index.

• bAlign (bool) – Aligned.

• bLocal (bool) – Local.

• bInitial (bool) – Initial

• bLocal – If True then the alignment is done along the Z axis, otherwise it is Y.

Return type
