[Morphic] Re: chanllenges. Juan's new morphic

[Peace Jerome]

Hi Juan,

Thanks for responding to my request to make the new
morph stuff available.

I've had a channce to play with it. In its present
form it runs out of running room fairly quickly.

That said. The decomposition of morphs into location
and co-ordinate system seems promising.

I tried putting some Testmorphs together. The
behaviour was odd.  Turning a morph with submorphs
left the submorphs stationary relative to the world.
This surprised me.

In the full conception what are the locations relative
to? Their direct owners or the world?

Picking up a morph would move its submorphs but
rotating a morph would not. The brown move handle
worked only for morphs owned by the world. Using them
on submorphs got a debug due to a DNU. The grab handle
worked for moving the submorphs relative to their (now
former) owner.  Dropping the morphs did seem to
reimbed them however.

So at this stage what kind of encouragement/help are
you looking for?

Yours in service, -- Jerome Peace
