I have a direction vector on which I have to apply some rotation to align it to positive z-axis. To use Matrix.CreateRotationX(angle) of XNA, I need the angle for which I'd have to compute cos or tan inverse.

I think this is a complex task to do. Also, eventually those are also converted to sin(angle) and cos(angle) in the matrix.

Is there any inbuilt way to create rotation matrix from a 3D vector?

However, I can write the function but still asking if there is one already there.

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
