Hi, Thank you all
Actually I am using Intersectionvisitor for this purpose. I will explain the scenario more clearly I will make up a line segment with end points say p1(10,10,1100) and p2(10,10,-100). Along the length of this line(along z-axis, between 1100 and -100) I want to find out all the intervals occupied by other objects and also their geode names if possible. For example I have two cubes which span as follows : 1) z=200 to z=300 2) z=500 to z=600 Note: we wont worry about the other dimensions of the cube we are only concerned about the distance spanned by the cubes along z-axis only because all our line-segments are going to be parallel to y-axis. So I want the result to be the point of intersections with these objects which I assume to be (_,_,600), (_,_,500),(_,_,300),(_,_,200). If I get this form of result I am perfectly fine.This means that an object begins at 600 and ends at 500 and then begins at 300 and ends at 200. But when I am using IntersectVisitor I am getting same intersection point twice or more sometimes. For example in the above case I expect 4 intersections but I am getting 4 or 5 or 6 or 7 or more intersections. So I can resolve this If i can get the object(geode) name of the intersected object. But I think that is not possible with intersect visitor. How can I solve this problem now?
