Thanks Chris,
The human scale environment/object set i wish to
draw doesnt exist until I pick up the stylus and start scribbling, in 3D real
space. Sort of like what Man Ray, Len Lye and Picasso (the bull
photo-images from him waving a light point around with the shutter left wide
open for a few minutes and final flash just to fill in the artist) et al did in
2D ... who hasnt?
I see the stylus as having a start button and once
the start button is open then a click button to select the node points to be
recorded as needed. Then close the on button when an array of nodes is
completed. The nodes are then dealt with in whatever way necessary ... spline,
etc.
I think it may need two horizontal point
transmitters and one vertical (perpendicular to one of the two horizontal point)
at precisely known distances to each other. These three should be enough to give
height and distance separation readouts for the stylus although maybe a
tetrahedral array of transmitters would make things faile safe. Or they would be
the receivers and the stylus would be a transmitter ... whatever.
It's a public holiday here today so time for
dreaming is permitted.
Thanks for your post,
Neil Cooke

Hello Neil,
We use Photomodeler from EOS Systems Inc. http://www.photomodeler.com/ Its
a software solution, rather than a hardware one. But It works out cheaper and
it uses Photometry to create a 3D model from Photos taken of an object from
various angles. It is still very time consuming for input, and models are
easier to input if you draw a grid on them first. The big advantage of this
system is that you can input an object of almost any size (as big as a church
or as small as a flea), as long as you can get enough photos from various
angles. The other advantage is that the Textures can be captured at the same
time and nailed to the model.
Hope this helps,

Hi List,
Does anyone know of a 3D drawing system that
can happen in real space.
On a plotter you move the pen from A to B and a
virtual 2D line happens, some plotters and mouse type inputs allow pressure
to set up a virtual line that lifts up or runs lower than the plotter
surface ... what I am interested in is a pen that simply runs in real space,
no plotter. It could trace surface lines of a face for example.
