How can I get a vector type in C#?

Question

I want to use Vectors in a C# application I'm writing, sepcifically a Vector3.

What's the best way for me to get a Vector type without writing my own?

Answer 1

I used one in a POC that I found on CodeProject. It's not ideal, but it worked for our situation. At the time, however, it did not have a method to reflect a Vector3 about a given normal, but that may have changed since then.

If you don't mind using DirectX (some stay away from it for whatever reason), then there is a Vector3 type in that library as well.

Answer 2

For completeness, there is also one in XNA: Microsoft.XNA.Framework.Vector3.

Sounds like something in dire need of consolidation.

Answer 3

In WPF you have:

System.Windows.Media.Media3D.Vector3D

Answer 4

You should be able to use the vector classes in SlimDX: http://code.google.com/p/slimdx/

You could also pull out the vector/math classes from an open source XNA port like XNATouch: http://xnatouch.codeplex.com/

Answer 5

Well, there's a struct called Microsoft.DirectX.Vector3 if that's what you're looking for. You need to reference Microsoft.DirectX.dll to use it.
