I just remembered an experiment I did a month ago which I wanted to share with you.
While playing with all the nice things in Scala for a while I thought it was time to create some basic Vector/Matrix math with it. Beside the obvious benefits like operators, I wanted to see if there are other things one can do with this expressive language.

So in the end I got way more features than expected:
  • vector/matrix size encoded as generic type parameters
  • type checked matrix multiplication(the width of the first matrix has to be the same as the height of the second)
  • unified types: a matrix with a width or height of 1 is a vector(I know that this might not be correct)
  • macro based vector swizzling
  • dynamic factories(i.e. create a 2x2 or 4x4 rotation matrix as needed)
  • size based optimized implementations(Vector3) which are hidden by the user. Also can be extended by user.

For code samples and some more in depth explanation take a look at:

I just wanted to put this out here to maybe get some comments or constructive criticism Smiley. In the spirit of perhaps inspiring someone else or getting inspired by some interesting idea from someone else.
