Benchmarking mathematical vector rotation through matrix-based and quaternion-based methods using BenchmarkDotNet to obtain memory-related, CPU-related and time-related information on these ops.
- Download Visual Studio 2017
- Open the VectorRotationBenchmarking.sln solution file
- Build the solution as Release, not Debug
- Go to your bin\Release folder in the project's folder on Windows Explorer and run VectorRotationBenchmarking.exe as admin for the Hardware Counters to work
It should take a while on average hardware. By the end of the run, you should have the results of the benchmark on your screen as well as in the BenchmarkDotNet.Artifacts folder inside bin\Release.
