3dImageViewer

Displays volume file as a voxel set by using QGLviewer.

Usage: 3dImageViewer [options] input

Allowed options are :

-h [ --help ]                    display this message
-i [ --input ] arg               vol file (.vol) , pgm3d (.p3d or .pgm3d) 
                                 file or sdp (sequence of discrete points)
--grid                           draw slice images using grid mode. 
--intergrid                      draw slice images using inter grid mode. 
--emptyMode                      remove the default boundingbox display 
--thresholdImage                 threshold the image to define binary shape
-m [ --thresholdMin ] arg (=0)   threshold min to define binary shape
-M [ --thresholdMax ] arg (=255) threshold max to define binary shape
-s [ --displaySDP ] arg          display a set of discrete points (.sdp)
--SDPindex arg                   specify the sdp index (by default 0,1,2).
--SDPball arg (=0.5)             use balls to display a set of discrete 
                                 points (used with displaySDP option)
--displayMesh arg                display a Mesh given in OFF or OFS format. 
--displayDigitalSurface          display the digital surface instead of 
                                 display all the set of voxels (used with 
                                 thresholdImage or displaySDP options)
--colorizeCC                     colorize each Connected Components of the 
                                 surface displayed by displayDigitalSurface 
                                 option.
-c [ --colorSDP ] arg            set the color  discrete points: r g b a 
--colorMesh arg                  set the color of Mesh (given from 
                                 displayMesh option) : r g b a 
-x [ --scaleX ] arg (=1)         set the scale value in the X direction 
                                 (default 1.0)
-y [ --scaleY ] arg (=1)         set the scale value in the Y direction 
                                 (default 1.0)
-z [ --scaleZ ] arg (=1)         set the scale value in the Z direction 
                                 (default 1.0)
--dicomMin arg (=-1000)          set minimum density threshold on Hounsfield 
                                 scale
--dicomMax arg (=3000)           set maximum density threshold on Hounsfield 
                                 scale
-t [ --transparency ] arg (=255) transparency

Example: With the image display you can also threshold the image and display a set of voxel:

3dImageViewer -i $DGtal/examples/samples/lobster.vol --thresholdImage -m 180

You should obtain such a result:

resulting visualisation of 3d image with thresholded set of voxels.
