Hello all,
Presuming that I can't get a hold of the source code, could someone
perhaps tell me how the Java3D VecMath package is implemented?
Specifically, I'm wondering if it makes use of the SIMD floating point
instructions on P-3 processors, and, more generally, how efficient it
is/what sort of performance to expect.
I'm looking at using Java for a major numerical analysis package, and
the "write once run anywhere" aspect is naturally quite apealing;
however, I'm simply unable to give up the traditional huge measure of
performance that goes with Java -- but the VecMath package seems quite
redeeming, provided the overhead is minimal. I'm guessing/presuming
that VecMath is implemented as efficiently as possible for the native
hardware; do I presume too much? If VecMath itself is implemented
"close to the hardware", how much penalty does the requisite Jini
boundary cost?
Further, could anyone comment on the general
state/availability/stability of Java3D and the associated VecMath
package?
Thanks in advance for all comments, etc!
-frank, always riding the bleeding edge......
