Create curved path/track

[teresap]

I have a question about creating a curved path/track that is visible to the user. I am able to make straight lines between various points in my environment using the code below, but I need a smooth curve (spline) to connect these points rather than straight lines. Any suggestions? I appreciate any help!

viz.startlayer(viz.LINES)
viz.vertex(0,0,-2)
viz.vertex(0,1.4,27.5)
viz.vertex(-1,-1.8,33.5)
viz.vertex(-1,-1.8,33.5)
viz.vertex(-4,0,38)
line1 = viz.endlayer()

You will need to break the curve into smaller line segments. The more line segments you use, the smoother the curve will appear.
