[ SUGGESTION ] GC Allocations

[PrisedRabbit]

Pls add the fix:

And is it possible to avoid of Marshal.PtrToStringAnsi() because of GC Allocations?

CalculateLookAt() should only be called once per frame, unless you are calling it yourself for some reason so it's unlikely to be a performance bottleneck. Do you have some profiling data that this is causing performance issues in your app?

Unfortunately in our current architecture we rely on passing strings to our C++ platform library which requires converting them to C Strings.
