How to get Fibers Object Record coordinates and show as text

I Got 2 files, 「Tracts_1.trk」and「Tracts_1.txt」.

According to XTK library API, it only accepted the Binary format file which is 「Tracts_1.trk」.

I know 「Tracts_1.trk」 inside record the files coordinates.

How to get the coordinates in the Fibers Object and show as text, just like 「Tracts_1.txt」?

I can't find any Property or Method can get it, please help me.

ps. Here is inside content：

Solution

  • I'm not sure to understand what you are trying to do.

    For each point in the tract, you want to show its coordinates as a caption?

    It is not supported right now.

    A workaround would be to loop around all the points in your tract, and for each of them create a sphere with the appropriate caption.

    http://jsfiddle.net/HZ38F/

      for ( var j = 0; j < numberOfPoints - 1; j++) {
    var currentPoint = fibers.points.get(j);
    var currentColor = fibers.colors.get(j);

    var newSphere = new X.sphere();
    newSphere.center = [currentPoint[0], currentPoint[1], currentPoint[2]];
    newSphere.color = [currentColor[0], currentColor[1], currentColor[2]];
    newSphere.radius = .1;
    newSphere.caption = 'x:  '+String(currentPoint[0])+'<br>y: '+String(currentPoint[1])+'<br>z: '+String(currentPoint[2]);
    r.add(newSphere);
}
