I'm looking for a SIMD library focused small (4x4) matrix operations for graphics. There's lots of single precision ones out there, but I need to support both single and double precision.

I've looked at Intel's IPP MX library, but I'd prefer something with source. I'm very interested in SSE3+ implementations of these particular operations:

  1. Mat4 * Mat4
  2. Mat4 * Vec4
  3. Mat4 * Array of Mat4
  4. Mat4 * Array of Vec4
  5. Mat4 inversion (nice to have)

Here's a project that isn't bad: SIMDx86, especially if you are just looking for source.

I don't see any evidence that supports double precision. – Joe Wreschnig Apr 22 '11 at 18:50
I'll bug the project maintainer about that... had thought it was. :( – ChrisE Apr 22 '11 at 19:43

Thanks, unfortunately no DP. It's actually really difficult to find, the closest was eigen.tuxfamily.org/index.php?title=Main_Page but this library looks a bit unfocused for games performance. – Justicle Apr 22 '11 at 22:01
If that was an answer, I'd vote it up. I don't think you will find any libraries focused on games supporting doubles, because you never really need vectorized doubles in games. – Joe Wreschnig Apr 23 '11 at 8:48
Its not strictly for a games dev project - but I usually get better answers on stuff like this here than stackoverflow - over there you just get "premature optimization" answers. – Justicle Apr 24 '11 at 2:35
