Space volume enumeration

Question

Hi.
Im trying to make the space volume enumeration of an object 3D.
In order to accomplish my objective i have made the following code:
Vector3d direction = new Vector3d(1, 0, 0);
for (double dz = 0; dz < 100; ++dz)
     for (double dy = 0; dy < 100; ++dy)
          //Posicao relativa do olho
          Point3d eyePos = new Point3d(0, dy, dz);
          pick.setShapeRay(eyePos, direction); // shoot ray downwards
          pres = pick.pickClosest();
          if ((pres != null) && (pres.numIntersections() > 1) )
                 pickedPoints = new Point3d[pres.numIntersections()];
                 for (int i = 0; i < pres.numIntersections(); ++i)
         pi = pres.getIntersection(i);
         pickedPoints[i] = pi.getPointCoordinatesVW();
} I have a problem. Because sometimes the number of pickedPoints are more than the number of interceptions betwen the ray and the object.
example: i send a ray against a sphere object and the code returns to points in duplicate:
(points returned):
1. pickedPoints[0].x = 0.5 pickedPoints[0].y = 1 pickedPoints[0].z = 6
2. pickedPoints[0].x = 0.5 pickedPoints[0].x = 1 pickedPoints[0].x = 6
3. pickedPoints[0].x = 7 pickedPoints[0].y = 1 pickedPoints[0].z = 6
The point3d 1. and 2. are equals.
Is that any away to get only the two points3d ( 1. and 3.) ?
thanks

Hi,
As you said a parity virtual disk should still working with 1 disk failure. I cannot confirm the exact cause at this moment. You may have a look on Event logs to see if any further information provided.
Meanwhile do you have a replacement hard disk? Try to add it to the pool, retire the corrupted hard disk and perform a repair to see if that could bring the virtual disk back online.

I have the replacement disk added.  I've retired the dead one, added the new one to the pool and attempted to run the repair from PowerShell.  It looks like it's going to do something but it pretty much completes instantly, so doesn't actually
do anything.  If I try remove the failed disk from the GUI it tells me that a repair will be done but without me even clicking anything, these dialogues disappear.
Looking in the event log, if I check the Operational log under "StorageSpaces-Driver" I see a message saying
Drives hosting data for virtual disk {ed94ba35-ea2b-11e2-93fa-00155d006604} have failed or are missing. As a result, no copy of data is available. Return Code: This device does not exist.
It's not looking promising that this storage space will be recoverable...
