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?
回答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.
回答2:
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.
回答3:
For completeness, there is also one in XNA: Microsoft.XNA.Framework.Vector3.
Sounds like something in dire need of consolidation.
回答4:
In WPF you have:
System.Windows.Media.Media3D.Vector3D
回答5:
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/
