Version 1.4

----------------------------------------

As requested by many students, I made public a simple interactive program prototype. Hope it may help those who want to play with or research on 3D point clouds. 

----------------------------------------

PcdViewer is my framework for 3D point cloud processing. It offers you some basic interactive operations such as select points by sketching a rectangle, or simply using the a lasso selection tool. 

----------------------------------------

Supported file format: 
  (1) xyz - ascii file with each line 3 float point numbers;
  (2) bxyz - binary xyz file;
  (3) pn (point with nomal) - ascii file with each line 6 float point numbers (x y z nx ny nz);
  (4) bpn - binary point with nomal;
  (5) lab - ascii file, with points label (segmentation) infomation;
  (6) blab - binary label (segmentation)  file;
  (7) pcd - ascii point cloud format.
You can find more information about the file format in the 'file_io.cpp' file. 

The source code can download here http://web.siat.ac.cn/~liangliang/software.htm
After decompression, please try the example data 'test_data.blab'.
