How to get the position of a vertex

[Jerry]

How can I get the position of a single vertex of an on-the-fly line?
The line has only two vertices and is being rotated by linking it
to an Intersense tracker. I want to obtain the positions of the
endpoints as it moves.

If you have the latest BETA version you can do the following:pos = line.getVertex(0) #Get raw position of vertex 0If you want to get the transformed vertex position then you will need to multiply the raw position with the lines transform:pos = viz.Vector(line.getVertex(0))
pos = pos * line.getMatrix()I've just added the ability to pass an optional parameter to getVertex which will automatically perform this calculation for you. It will be available in the next release.
