RE: FLASH: Flash 5/6 aka DirectFlash! Some suggestions

[Branden Hall]

Actually, that system does some just-plain-complex(tm) math...  lots of fun

calculus stuff (integration via Euler's method), and I am kinda sloppy with

my floating points...  I'm sure if I went in and did a few assembler-style

tricks to keep the code from ever using floats, it would speed up quite

nicely. The simple fact of the matter is that you have a 200K plugin that is

able to run some *serious* code pretty damn fast.  More than likely, F5 took

a sort-of RISC approach to be able to do all it does with that little...  in

other words, the F5 plugin is probably optimized up to wazoo for doing basic

operations, and have all complex operations exsist as combinations of the

basic ones. For example, when you export say, a square root call Flash

probably includes the math needed to do a newtons method to get the sqrt in

the SWF...  Otherwise I don't see how in the hell the plugin is still so

damn small.


Anyhoo... you have to look at all of the factors involved with why flash is

what it is...

Besides that, I honestly do not see video coming to Flash for a while... it

would just bloat the plugin too much.. and once browsers get their act

together they should all be able to do what I can do in IE... put a

quicktime above my flash movie.  Finally, as for JPG2000... I agree

totally... wavelets are the future!

Subject: FLASH: Flash 5/6 aka DirectFlash! Some suggestions



Heres a couple of suggestions for Flash 6:


Ive been looking at Branden Hall's sprung.swf Flash 5 demo. A 1-spring, 2

body system consumes 50-60% of my 600MHz CPU. Now Branden is a smart guy, so

I cant really imagine that hes implemented that demo too shabbily. If this

is anything like what we can expect, then the performance of ActionScript5

leaves a lot to be desired. Suggestion: Make ActionScript byte code

interpretation much much faster. For games, for anything requiring a modicum

of physical simulation or computation, a faster interpreter is needed.


Ive been looking at Moho from lostmarble.com. They have a lovely tool,

oriented around the concept of 'bones' and how 'bones' cause shapes to

morph. Unfortunately, it looks like the output filesizes of their tool are

going to be huge because bones arent supported by they Flash file format.

Morph shapes would be great if, rather than interpolating the control points

along linear paths, the control points were interpolated along curves.

Suggestion: add a Morph Shape tag/command that supports interpolation of

control points along curves rather than lines. A better suggestion: Buy

lostmarble and incorporate their animation technology into Flash 6. Another

suggestion: Fully integrate the bones feature into flash and make it

programmable/accessible through actionscript. Something like this would help

us escape the stiff animations we now create, while maintaining a small

filesize.


Flash really falters when it comes to video. I know there are a lot of

competing video technologies out there, but, going forward, video sprites

are pretty much a must-have feature. Suggestion: Pick a video compression

technology and go with it. Even a proprietary tech would be perfectly

acceptable, although implementing a single Quicktime codec (e.g. sorenson or

somesuch) or MPEG1/2 might make more sense.


Alpha channels - It would be lovely to be able to retain alpha channels in

lossless compressed images. Import as PNG/TIFF/RGBA, output as

JPEG(ish)/RGBA. Also, JPEG2000 is just around the corner, and the

compression ratios possible with JPEG2000 are way beyond what is possible

with JPEG. Lets have the very best possible compression tech implemented in

Flash, so that we can keep our file sizes really small while extending our

ability to use photographs freely.
