Looking for way to make/input patterns

Post by Sean Smit » Sat, 09 Oct 1999 04:00:00



Hi all,

    I'm looking for some way of making a pattern and having it input
directly into a computer accurately.  The surface is a bit irregular and it
will be curved in places.  I'd like to be able to get some sort of input
device that I run around the inside dimension of the item and it draws a
pattern or outline in the computer.  We'd be possibly using a program like
Corel Draw unless someone else knows of a drawing program that would output
to a DXF, PLT, or NC data format.

    The surface we'd be tracing the inside dimension of would most typically
be carpeted.  Ideas were thrown at me about using a mouse or a pen-like
mouse device but since the mouse/pen ball position is sensitive to changes
in the angle, this wouldn't yield an accurate pattern and it would most
likely fill up with debris, making it hard to keep clean.

    I looked at a couple of digitizer input devices but since they require
having an set absolute zero point, they're typically either attached to a
tablet or are on an arm to keep the reference point.  Since this will not be
an easy surface to get to, arms and tablets are not feasible.

    If anyone has any ideas or knows of a company with a product which will
do hat I need, please let me know.

    Thanks,

    Sean

I don't know about software, but I once saw a mousepen in action and I
think it would do the trick for your as far as an input device goes. It
works just like a rolling ball pen, so it has little opportunity to pick
up debris via static as a mouseball will. The one I saw was attached to
a Macintosh, however I'm *sure* I've seen them for both religions ;->

Just an idea... hope it helps...

  Not possible at less than $$,$$$ ... a mouse or mouse-pen knows
in what direction it moved, but not how far, because of the lack
of a zero reference point.  
  "Graphics tablets" have a grid of wires inside them so they
know where the cursor is relativeto the tablet ... but you can't
use the cursor off the tablet.

  What's your budget like?  there ARE 3-D surface scanners, but
not cheap.  Not at all cheap!

    I was looking at the mousepen but the problem comes in with orientation
of the pen and the pickup of debris.  We would be tracing the floorpan of
the interior of a car, any movement of the mouse other than the straight
marks required for inputting an accurate pattern would result in a very
skewed image.  I'm looking for something with a more absolute X-Y
orientation.

    Budget?  I need to get ideas and solutions and THEN look at the price
and let them balk or go for it.  IT all depends on how much they want to get
this project done in a certain amount of time.

    Either that or they take patterns from 200+ vehicles with paper and
crayons like they've been doing.  ;>

Laser mouse? They seem to work on any surface.

    I've never seen nor heard of this product, any places where I can see
one (on the net)?

No idea...I think Sun makes them, but maybe they are just for Sun
workstations. Either that or Silicon Graphics.

Now that I think of it, the only time I've used laser mice was with
either of those machines! Maybe that was no help at all.
