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?
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.
