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, .longvol .p3d, .pgm3d and if
                                  WITH_ITK is selected: dicom, dcm, mha, mhd) 
                                  or sdp (sequence of discrete points). For 
                                  longvol, dicom, dcm, mha or mhd formats, the 
                                  input values are linearly scaled between 0 and 255.
 --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)
--rescaleInputMin arg (=0)       min value used to rescale the input 
                                 intensity (to avoid basic cast into 8  bits 
                                 image).
--rescaleInputMax arg (=255)     max value used to rescale the input 
                                 intensity (to avoid basic cast into 8 bits 
                                 image).
 -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.
