#Skin question
7 messages in this thread
I am working on an animation of a printing press and plan to use Skin.axp for
the paper running through the complex roller system. Has anyone else tried
this approach? I'm wondering if it is possible to apply mapping in a way that
will allow me to use an animated map of advancing paper that will follow the
bends and turns of my skin sections. Any tips?
Thanks
Mitch
Sounds doable (and pretty straightforward) to me.

Yeah, Gary's right. It sounds real straightforward. I'd create a Skin object
that covers the whole length of the paper's path, then create both an animated
opacity map and an anim texture map that have the right speed to match the
rollers. The hard part, I think, would be to match the curves in between the
rollers with your Skin. Good luck!

Why skin? For your project, I'd probably not use skin at all. Mainly because
I'd want a lot of control on the mapping. I suggest creating a path in the
shaper that follows the route of the paper through the system. Then create a
shape that represents the paper – a very thin rectangle. Loft the shape along
the path and turn mapping on, normalize length on, length repeat (the total
lenghth of the path divided by the length of a sheet of paper), perimater
repeat 2. Then you'd just need to create an animated texture map of the paper
in motion. You may need to fine tune the loft mapping co-ordinates. Also
fine-tuning can be done on the material level, such as rotating, scaling, and
UV co-ords of the texture map.
I just tried the lofting technique with the 3d cel texmap, and it looks good to
me.
Sounds like a fun project. Good luck.
You could also use Martin's technique and create a series of morph targets
for the paper and skip the animated-map creation.

You may want to try using Grids.pxp to define your paper mesh lattice for
Skin….it works if it's a 2D grid. Then use bend/rotate on selected vertices
to conform to the paper's path.

Hi mitch; Schriper insturments has an IPAS called Python, it creates morth
objects
that follow a path. It's usefull for things like 3-D write on's. It might be
another way
of moving the paper through the press.
