I'm a Windows programmer needing SSE batch trig routines. I've written SinCos myself based on a research paper I found, that had an Altivec implementation. I have discovered that the vForce part of the Accelerate library has all the batch functions I could want and then some: http://developer.app...section_14.html

Unfortunately, since I don't have a Mac, I can't install XCode and look for this lib. The header file is vForce.h. Would the SSE or Altivec implementations perhaps be available? IF someone could point me to a tarball with the vForce source or email me (spec at ript (nospam) dot net or lightborn at gmail (nospam) dot com) I'd be really, really grateful.

I think its legal for me to post this...it's open source (or Apple's version) right? Hrm.

/* 
When the float versions of the vector functions (vvrecf(), vvdivf(), etc.) are invoked on platforms equipped
with the AltiVec SIMD unit, they expect that "Java Mode" has been established in the AltiVec VSCR register.
"Java Mode" entails flushing de-normal vector floating point values to zero. Mac OS X sets the AltiVec VSCR
register to "Java Mode" by default when a new process is created. A process running in "Java Mode" enjoys 
performance advantages when executing AltiVec floating point instructions.

The double versions of the vector functions must be called with the IEEE rounding mode set to round-to-nearest and with exceptions masked off. 

The accuracy of the vector functions is comparable to that of the corresponding scalar functions in libm, though results may not be bit-wise identical.
