Is there somebody out there who can introduce me to the art of How-to-use-SANE ? I am writing an interactive simulation application (biomechanics) which involves some heavy number crunching in the motion integration loop. In particular the simulation may well go unstable and I need to catch that before the Mac crashes... So I need to monitor the floating point operations and I think that's what SANE is made for. I would be happy to hear about how to do that in a reasonable way. For instance I assume that not every single FP operation has to be checked but only a few critical ones, right ? Any advice welcome, example codes, pointers to references (pretty indirect, no?) Thanks in advance. PS: The application has 3D graphical output for the simulation (pseudo-real time). Sofar I convert directly from floating point world coordinates to integer screen coordinates. Would it be more efficient to use a type like Fixed or Frac for the world coord's (in terms of speed ?)

Dear Phillipee - What you need is a copy of the SANE Bible - "Apple Numerics Manual, Second Edition". It is published through Addison-Wesley and is available at the more technical bookstores around and from APDA at 1-800-282-APDA. -- Jordan Mattson UUCP: jordan@apple.apple.com Apple Computer, Inc.
