I am drawing two points in the helixviewport3d using the following code. How can I offset/translate the points to new positions?

var result = new Point3DCollection(n);

var pt1 = new Point3D(0, 0, 0);
var pt2 = new Point3D(5, 5, 5);


VisualPoints = new PointsVisual3D();
VisualPoints.Points = result;

Actually, I want to translate the two points to different locations. Applying translate transform to the VisualPoints would result in the translation of both the points to the same new location. Am I right in this?

Actually, I have about 300,000 points in "result" and I want to translate each point to a new position. I tried doing result[0].Offset(xnew,ynew,znew); but I found that the offset applies on a copy and not on the original point. So, other possible way is to replace all the points in "result" with new points (with new positions). Are there any other workarounds?
