Great !

I have also received several updates by Omar.

I'll try to put online both yours and his data ASAP!

> <para>Hooks give access at object level to the underlying geometry of
meshes, curves, surfaces or lattices. A hook is an object feature and it is
like a parent to an object, but for vertices. You can create as many hooks
to an object as you like, and assign for each hook vertices that will be
affected. Overlapping hooks is also possible, here a weighting factor per
hook is provided that determines the amount each hook will affect the
overlapping vertices.</para>

reassign exsisting hooks as well.</para></note>

options are available in edit mode for meshes, curves, surfaces and
lattices. Select any number of vertices, and press <keycap>Ctrl H</keycap>
to access the hooks menu.</para>

empty object, that will be a parent to the selection, at the center of the
selection.</para>

selected (you can do that in edit mode with <keycap>Ctrl
RightMouseButton</keycap>) the new hook is created and parented to that
object.</para>

Only in object mode you can actually use the hooks. All object level options
and transformations are possible now, including using hierarchies,
constraints, ipo and path animations.</para>

you don't want object transformations to deform the hooks.</para>

(<keycap>F7</keycap>) in the <literal>Hooks</literal> tab. Here you can give
a hook a new name, the default name is the parent name, give it a new parent
by typing the new parents name or assign it a <literal>Force</literal>
weighting factor.</para>

vertices, you can weight the influence of a hook this way. Weighting rules
are: </para>

1.0-forces, will be the factor the original position have as force.</para>

hook transformations, averaged by their weights.</para>
> </listitem>
> </itemizedlist>
> <para><keycap>Falloff</keycap> If not zero, the falloff is the distance
where the influence of a hook goes to zero. It currently uses a smooth
interpolation, comparable to the <literal>Proportional Editing
Tools</literal>. ( See <xref linkend = "mesh_modeling_PET"/> )</para>
> <para><keycap>Delete</keycap> Delete the hook from the object.</para>
> <para><keycap>Clear offset</keycap> Neutralize the current transformation
of a hook.</para>
