I am attaching for comment and feedback my first version of a digitizer import plugin for CamBam. Given that we have a point cloud (as a text file containing point X,Y,Z coordinates, one point per line) then the plugin will:
(1) Import the data, and display the number of points and the X, Y and Z ranges
(2) Allow the user to set offsets (in X,Y and X) and scales for X, Y and Z to transform the data
(3) Create a triangulated surface using a Delaunay triangulation process on the transformed model.
(4) Save the result in an STL file
(5) Optionally import this file/model into CamBam
The plugin does not generate the digitized cloud data, that must come form another source

Comments, feedback and bug reports appreciated
