Class LineGraphDrawer

Makes it extremely easy to 'draw' a road graph. Just add lines/edges and close enough vertices will automatically be joined together.

Syntax
public class LineGraphDrawer
Examples
void Example()
{
    // create a drawer which merges vertices that are closer than .1f
    var drawer = new LineGraphDrawer(.1f);

    // draw a square
    drawer.AddUndirected(new float3(0, 0, 0), new float3(1, 0, 0));
    drawer.AddUndirected(new float3(1, 0, 0), new float3(1, 1, 0));
    drawer.AddUndirected(new float3(1, 1, 0), new float3(0, 1, 0));
    drawer.AddUndirected(new float3(0, 1, 0), new float3(0, 0, 0));

    // create our graph
    var graph = new LineGraph(Allocator.Persistent);

    // populate it with our square
    graph.Populate(drawer.Vertices, drawer.UndirectedEdges);
}
