Create points ROI

To create 3D image from text file with voxel value and coordinates.

Description

To create 3D image from text file with voxel value and coordinates.

Text file format
Each line corresponds informations of one point :
voxel_value coordX coordY coordZ

Example :
10 45 56 78
45 45 78 56
30 45 85 69

This file indicates 3 points :
point number#1 : voxel value is 10 and coordinates are (45, 56, 78)
point number#2 : voxel value is 45 and coordinates are (45, 78, 56)
point number#3 : voxel value is 30 and coordinates are (45, 85, 69)

Note : Referential of coordinates points is image referential. Origine image (0, 0, 0) is the voxel at the top, font and right of volume. If your points are in another referential you must compute coordinates in referential image.

Image format:
3D image will be create with informations (dimX ......) and initialized with data of 'file_of_point'.

To create ROI graph from new image :
ROI graph can be create with AimsGraphConvert. Here, you must know that all voxels with same value voxel will be put in same node.
