Hello!
A code with various vector functions (including distance between point/line, point/line segment etc.):
vec3dA doubly linked list:
listvec3d uses own vector structs, because the range of var is too limited for some operations.
Sorry, I can't give you more info about this at the moment, as I'm at work. However it's pretty well documented (in german) and I'm back at home this evening if you have any questions or problems.
Hope this helps. : )
