I saw administrator’s classic example about the lineSegment.It’s great! But if i want to move a line’s positon or change other properties,how can I get the lineSegement object from SegmentSet? It looks like SegmentSet Class has no method to support to get line object from SegmentSet.

I’ve worked with them so I know how to use them, but from the point of view of hardware what is a segment made of? Are they vertex/polygon based? Do they run on the GPU via shaders? |
