3-D-E Visualiser and Contour Editor

3-D-E, supplied by Data Cell, is a Windows based software product designed to take 
2D image data and reconstruct to a 3-D surface rendered object.  It allows the user to 
view, rotate and zoom under mouse control in real time on a 486 PC.

Applications
  Confocal Microscopy
  Cell Analysis
  MRI and CT Scanning
  Sequence Tracking
  Laser Profiling
  Research and Development

3-D-E comes with a contour editor used to generate a wire frame data set from 2-D 
images and a Visualiser which takes the wire frame data and renders it using lighting, 
camera and shading parameters.

Visualiser Features
  Accepts 3-D data from the Contour Editor or ASCII ams file.
  Real Time Zooming and Rotating under mouse control
  Ability to view inside by interactively changing cut plane.
  External and internal Rendering

More than one object can be viewed at once and rotated independently while objects 
of different colours maybe defined within an object to show internal workings.  The 
image window can be copied into the clipboard and pasted into word-processing and 
graphical packages for report generation.

The Contour Editor is used to load a set of image slices and define them as a sequence 
with a Z distance between each slice.  The contour of each image is drawn around 
the perimeter using the mouse in a point and click fashion.  Contours are then repeated 
and edited for subsequent images until all contours have been drawn. The constructed 
object can be seen in the Viewer by launching it from the editor.

As well as manually drawing contours, boundary points can be loaded in from 
packages like Optimas where they are generated automatically.  An Optimas macro is 
available which generates boundary points of a chosen segment length and converts 
the data to a contour file.  In addition, the macro can be linked to the Sequence 
Extension available with Optimas to automate the complete image set.

Contour Editor Features
  Uses Industry Standard file formats including tif, bmp and jpg
  Contours can be re-edited at any stage
  Contours can be pasted between slices and shifted, rotated and zoomed.
  Generates ASCII ams files for loading into the 3-D Viewer
  Several ams files can be pasted together to generate objects within objects

Both the Editor and Visualiser come with full on-line help and a manual that explains 
the technical aspects of the software.

The cost of 3-D-E is 995 and is available from  Data Cell Ltd.
