Very cool stuff. I keep debating on whether I should spend some of my very limited free time on Haxe. Things like this are making it hard for me to avoid!

[...] haXe compiled code is generally more optimized than Adobe’s but this test does not let haXe show its strength in this regard: if you want to be blown away by the fast memory API + haXe’s awesome compiler optimizations read this post about an haXe version of an Alchemy experiment. [...]

truly inspiring! keep the experiments coming :)

i love haXe

[...] in particular its unique Flash 10 memory access – the memory model which powers Alchemy, so haXe can be as fast as Alchemy without the crazy C compilation and wrapper stuff. haXe’s Flash target also features some [...]

Hi again! :) /Thanks for Your e-mail!/
Whene I tried to fix the upper mentioned HaXe bug, I have found an optimization.
In the AS3 reference, I read, that Vector3D.X_AXIS is a constant, so I replace it with my own
private static inline var X_axis : Vector3D = new Vector3D(1, 0, 0); private static inline var Y_axis : Vector3D = new Vector3D(0, 1, 0);
static variables. The result, with 1 million particles:
11 FPS with Vector3D.X_AXIS.
14 FPS with static X_axis. (cca. 20% speed up is not bad.)
And it is working well with 300k particles, too.

Hmm. Strange. In Your code the in the updateMatrix option use the:
matrix.appendRotation( flash.Memory.getFloat(_tx), Vector3D.Y_AXIS ); matrix.appendRotation( flash.Memory.getFloat(_ty), Vector3D.X_AXIS );
But whene i try to compile, HaXe says: there are no Y_AXIS, X_AXIS field the Vector3D class, and did not compile the swf.
If i modify these 2 into YAXIS, XAXIS, then HaXe compile the code without any error message, but the swf does not draw anything.
If i comment out this 2 line, then thew swf draw the particles, but no rotation.
Any idea?

hi tony, good idea and thought the same myself; need to port mr doobs stats class over to haXe! unless there is already one or somebody else has done this?

This is great - i've been waiting for this to be done for a while - a perfect exampe of the power of haxe! One thins which you REALLY need to add is the same fps/memory counter in the top left - this will allow people to see the speed difference more clearly. I hope you can add this soon - and then lets show this puppy off ;P

strange, mine and ralphs both use the new opcodes supported in alchemy and haxe - maybe the plugin version doesn't support them in 64bit ubuntu? I'd test but I can only check in 32 bit here as running it in openbox on 32bit vista

None of the haxe links are working for me (blank screen). 64 bit Ubuntu (64 bit plugin)
Ralphs did not work
Joa Ebert worked

None of yours. Wonder what is going on?
