Log:
increased performance of operator*( quat, quat) by 33%
this in effect increased performance of Xforms xform(quat,vec) and operator*(q,v) by 12% for
floating (32 and 64), and by 30% for integer types.
did this with return value optimization. previously this func was using mult(), which needed a
temporary to prevent aliasing. operator* has no aliasing problems, so could be optimized...

fixes a few broken test cases in the test suite.
Fixed div( Quat, Quat ) to work right (see QuatOpsTest::testQuatDiv() in
the test suite) it is defined as q1 * (1/q2).
added / and /= for quat division.

I fixed the 4 errors that the test suite had. Justin, make sure I didn't break something in quat mult. I seem to remember you had to swap around the mult function for some reason (to make *= work?), anyway, I found it computing the wrong value tonight, so I've checked in a fix for it (I had to swap the q1 and q2 in mult()). This contributed to fixing the test suite as well. (I had to manually fix a couple funcs). Anyway, I'm not sure what happened, but stuff should be more accurate now. Let me know if not. For everyone, lets try not to ignore the errors in the future (anyone want to tackle testMatrixgetRotEuler?). Next time you change something, just run the suite, thats what it's there for (its your friend). announce anything that isn't yours, or fix it yourself, it usually doesn't take long. - kevin On Sun, 16 Mar 2003, Kevin Meinert wrote: > subatomic 2003/03/16 20:04:44 PST > > Modified files: > modules/GMTL/gmtl QuatOps.h > Log: > swapped args on mult( Quat, Quat ) to match the matrix version (see test > QuatOpsTest::testQuatMult() in the test suite).
