there doesn't seem to be much reason for a 3-D
worker to return to director this release :-(
hopefully will get a .5 release this time. the .5
releases seem better for 3-D people like us. ;-)
but the very good new is, that director seems to
get more attention from macromedia, than many of
us believed some month ago...
I think the feuture set for DMX 2004 shows it very clearly.
juhu !

Hey there,
frequent reader, occasional contributor, but now I need advice.
I'm about to start showing a video within a relatively complex 3d-scene
at some point (via constantly replacing the "cinema's" texture with an
actual video frame).
I've tried to use the ChromeXtra-methods for real video, but it showed
that the video struggles - it's far from fluent video. That
unfortunately is a no go for my project, so I'm trying to use another
method.
Showing a Quicktime video "off screen" and copying the corresponding
proportion of the stage image like Tom Higgins describes on
http://poppy.macromedia.com/~thiggins/flash_integration/flashvideo/index.htm
is a working method in theory (it is MUCH FASTER than using real
video!) - my problem is just that I cannot use a web browser movie, but
a stand alone projector, and thus this method doesn't work anymore: As
soon as the video sprite is not visible on the stage any more, also the
stage image will not contain any video frame to copy into an image
object for use as texture.image.
Perhaps someone out there can help me with this - anyone has got any
clue about how to accomplish this task?
Thanks a load in advance,
roman bl�th.

In a projector case, you could play the video in a hidden MIAW, and
get the image of the MIAW window.

Easy: Play the video in a MIAW and take the image of the MIAW. It can be
off-screen, of course.

You might try placing the video on the stage somewhere underneath the DTS 3D
member. It won't show up to the viewer, but it'll appear on the stage.image.
I know that someone did this a while back with Flash, but I do remember some
people complaining about problems with flickering.
If not, you could use a MIAW to play the video. If you open the window and
hide it, I think you can still get its image.

Hi,
try putting the Quicktime in a MIAW the same size as the video. You don't
even need to open it - just declare it, send the Quicktime to the frame you
need, and grab the window's image
i.e.
grab = window("MovieWithAQuickTimeInIt")
tell grab
sprite(1).movietime = thisframetime
end tell
imageGrab = grab.image
or
open the window offscreen and have the video playing, and just grab the
window's image each time you need a frame
hope this helps,
Martin Pallett

Dear wizards,
concerning the subject above, you helped me a lot! It works both ways,
putting the video sprite behind the DTS 3D sprite and showing the
video in a MIAW. I have to compare the performances of both methods,
but both are much better than working with Real Video.
Thank you guys, you quite made my day!
Best regards,
roman bl�th.

Hi,
Was the dummy "removedFromWorld" ? I remember having trouble with this several
months ago, and it was precisely because of that (took a while to find out...).
I can't remember what problem(s) was occuring because of this though :/

Danny's got it correct, we used the SpiderMonkey engine and so your JS
syntax scripts and your Lingo scripts are in fact compiled to separate
byte-code then run through different execution engines at run-time. The
truth is that Lingo is generally faster than JavaScript syntax, there are
areas where JS syntax can provide equivalent or possibly better performance
than Lingo (text searching using regular expressions), but in general Lingo
wins. When implementing this engine our primary concern for this release was
to get it in place and stable, we did not want to get into the SpiderMonkey
engine itself and try to do any tweaks other than what was really necessary,
as such performance optimizations of the engine wasn't on the feature list.
We did work to optimize the communication layer between the two syntax
options and we are in general on par with or faster than JavaScript in the
browser and ActionScript in Flash. Maybe next release we can look at
internal performance optimizations in the JS engine we've incorporated, but
this release needed to be stable and complete, we think we've done that.

My response:
Well, for one Virtools.
Virtools also has Havok physics capabilites (costs extra) but it is twice as
fast as Director, and it runs in a browser. Very expensive, but if you teach
(like me) or if you are a student you can get educational version.
Their 'rubber ducky' physics demo ran FAST on a 4MB intel gfx card on with a
450 mhz processor on a machine built in 1997 with Windows 98. I was impressed.
That same old computer runs Director3D so slow it is barely playable.
Second: Blitz3D
Blitz3D is FAST. Although the code is based on Basic and very easy to write and
read, it is compiled to C++ code and apps run fast, hence the name 'Blitz'.
Some Blitz coders have written physics .dlls, all of which are free and I think
one is open source. I have seen ragdoll, cloth, rigid body physics in Blitz
using these demos and they are very fast. When I bought Blitz it was only $150
and now the price has even dropped to $100. the site is blitzbasic.com but the
hangout place for all of us coders is blitzcoder.com Just make sure if you buy
to buy from blitzbasic.com...that will allow you to get the most recent engine
updates, which are crucial.
If you want to look at physics in Blitz poke around on blitzcoder.com The user
community is huge. I've finished 2 complete 3D games in it and it's pure bliss.
And a great exporting pipeline for models and animations from 3Ds Max to Blitz
is available.
Third: QUEST3D
Quest3D is probably the fastest of all of these. Similar to Virtools, it has a
visual authoring system but you can also write scripts and even your own C++
building blocks if you so desire.
Quest is relatively inexpensive and comes with built in physics that are
awesome. It runs in a browser like Virtools and it has pathfinding,
pixelshaders, realtime shadows (pro version) and tons of other stuff. It's the
envy of the real time 3D world right now IMHO. I bought the LITE version and I
love it. (only $89)...not bad considering physics included!
Quest3D has the best realtime physics car demo I have ever seen. I found it
somewhere on the user forums....its called the 'buggy' demo. It has a
suspension and shocks system that is very nice...built by a university student
somewhere. Amazing and very very fast. That is what sold me on Quest3D. I
think you have to download the free trial version to play the buggy demo, if
you can find the buggy on the user boards. if you can't find it I can direct
you.
3dGamestudio A6 also has physics in the commercial and pro versions. A6 cannot
run in a browser, though. But the userbase is ENORMOUS. On the Conitec
website, they have a comparison of about 20 game creation apps, all of which I
have looked into, and 5 of which have physics. The comparison is a little
outdated, but it's here:
http://www.conitec.net/a4faq.htm
I cannot testify for 3dGamestudio A6 because I have not tried it.
Director is a killer app, and nothing can compare to it in its own league, but
I just wanted to shed some light on other apps that have really focused on
realtime 3D authoring, since I have received two questions about it so far.
