Software to display 3d vectors

[elexhobby]

Hi

I'm working on some ray tracing using Snell's law, etc. and would like to know if there is a software which displays a 3d line. I would basically like to enter the start and end points, or start point and start direction, and would the 3d vector to be displayed.

The ray tracing/CAD softwares that I searched for the net are way too complicated. What I need is pretty elementary. Please help.

Thanks.

I haven't looked at it in a few years, but vPython should be able to do this. I remember it being easy to use, as I was playing with it when I was just learning Python.
