C# Line from Vector3d

Hi all,

was reading a discussion about vetors http://www.grasshopper3d.com/forum/topics/virtual-cross-of-two-vectors

and tried rebuilding it in C#.

Using the first Vector it works expected, the second vector shows strange behaviour.

Maybe someone could tell me what am i doing wrong?

Thanks in advance!

What output are you expecting here?

A line, like when i plug it in the first vector(berween 1+2 point). As i understand i can get a point from the vector coordinates and create a line like with sdl component.but the line is displaced because the point is created in (0,0,0)instead of (27,0,0)

There's a certain confusion here.

But never fear, Smith is here.

Get this "entry" level vector thingy (for the long winter nights, Tequila optional)

Moral: long is the path (and hilly)

Hey,

sorry for confusing everybody and thanks for everybodies effort on this !

I had a look at the EssentialMathematicsForComputationalDesign and realized i will need to feed a Point in for getting the result i want. Think it was quite obviously when i see the native GH components, the vector display also requieres a startpoint, i misunderstood the principle of vectormath in this point.

Next time i will check this paper before asking stupid questions,hehe.
