        While I am excited to hear about this new product - it seems like these are
wrapper (no pun intended) to Wrap and Shape from Raindrop. WHich in itself
is not bad since those are good products (or Ping should be yelling -
Copyright violation of trademark names - just kidding - I am not a
spokesperson for Raindrop). But is that the case or is it truly a new
product? What was your bench mark data. Can you share that with us.
        I am also interested in teh 3D logo or texture. Was the texture a raised
logo i.e. the geometry of the surface was modified ? THis is a research
issue I am interested in myself.

Hello All

Read carefully all those interested in removing the pain associated with RE.
I believe that I have found the long awaited solution toolkit (and I
emphasise the word solution).

I apologise in advance for my ramblings but I am very excited about what
this suite of tools is going to enable me to do.

Delcam Plc, a CAD CAM software vendor well known within the tooling market
place, kindly invited me to their recent international sales partner event.
This gave me the opportunity to view all of their products with respect to
They have a suite of tools called the Power Solution which embraces the
power of OLE and Visual Basic. The result is a set of tools which I believe
can solve all RE avenues.

CopyCAD is their front end tool which will read and handle all types of
point cloud data whether it be unordered, scanline or structured grid data.
It even has different algorithms (for triangulation etc) to maximise upon
the information held within the different types of data.
The triangulation (polygonisation) algorithms are in my opinion only
paralleled by that available within Polyworks.

The process of fitting accurate surface patches is quick, simple, and
interactive (I know it's hard to believe). In fact we managed to fit
surfaces to my benchmark data set in minutes!! It even generated the error
maps (points to surface) automatically.

The one feature that I have not seen in any other RE products is that of
wrapping 3D decoration and textures onto surface geometry. Wrap, a module
within CopyCAD, allowed them to add a complex 3d logo to the multi-curved
surface we created. The result was exported as a water tight STL model (for
RP or high speed milling).
They also have a module called TriFIX in CopyCAD which cleans up the model
ready for RP. I am told that this tool on it's own is used by the RP&T
centre at Warwick University (the largest in Europe).

The OLE link means that surfaces generated in CopyCAD can be pushed directly
into their hybrid modelling package called PowerSHAPE. The
