Sorry all. Bad habit in Outlook of just hitting reply. I will be more
careful in the future. Of course, in order to get that many lines, others
have been not deleting residue as well.
Thanks for the tip.

Ken, please can you be a little bit more careful with your quoting style ?
your last mail had nearly 400 lines with one
simple single line question at the top.
that's an annoying waste of bandwith.

Well, this is not as easy as it should be - after having read all the
tipps & tricks concerning 3d and video I decided to set the playback
rate of my movie to 15 fps as soon as the movie starts to play, since
that is the frame rate of the movie and somewhere someone stated that
setting the playback rate to the movie's frame rate should do good for
the performance.
So I play both - the movie and the video - with 15 fps. And there is no
difference in frame rates whether I use real video or quicktime. But
when I use real video the movie swallows most video frames, so that the
frame rate of the director movie is not affected, but the movie itself
is really really stop motion. Not so with quicktime. But maybe this has
got to do with my computer - though it is an Athlon XP 2000+ it has only
256 MB RAM, which might not be enough alongside with a display
resolution of 1600*1200 pixels (the graphics card is fast - it's a ATI
Radeon 9800 Pro.
So I could comment out the playback rate restriction, but I doubt these
numbers would show the difference between the two video types here...
Trust me, the real video plays awfully within the 3D-scene here (as I
said king of stop-motion), the quicktime is much faster / better
performing / much more fluently playing.
Best regards and have a good week over there,
roman bl�th.

Hi,
My artists render height maps for me, but they are in grayscale. Does anyone
know how they can render them so that they use all three colors, giving me
16 mill precision instead of 255?
Jack.

Just curious....of the thousands of Developers who use Director, only a few can
have their games featured on Shockwave.com
What are the barriers to entry (other than financial)? Is it based on
subjective criteria relating to potential marketability of the game?
I have new project now that I'm building a team of artists and coders for that
needs to hit the mass market. Shockwave seems to be an excellent distribution
system.
At any rate, any advice?

I know in photoshop it's possible to have a 16-bit grayscale image which
would give you 65,536 levels or so, but as far as I'm aware, there's not
a 24/32bit option.
Hope that helps.
Greg :)

When changing the currenttime of a keyframe object, it doesn't update its
position before the object is drawn. Does anyone know if there is a
workaround for this?

You can either write a raycaster in max/maxscript, and use that to
generate a 24bit heightmap.
You could do the same in director.
You can also have them export to RLA, and use the Z component, it
supports 16bits zdepth if I'm not mistaking. (you'll have to double
check though).
problem with 1 and 2 is that you have to do work :), problem with 3 is
that the rla format is pretty badly documented (at least it was in 2000
when I used it for heightmap export).
I don't know how they now export their heightmaps, but it usually helps
a lot if you at least use _all_ of the 256 discrete steps. Sometimes an
artist will have something far away, or closeby in the render, which
will cause the 256 steps to be stretched out way further than it needs
to be, giving you a lot less precision than what 256 steps could give you.
Good luck, Lucas

hehe, draw it :).. if you need access right away, you can try this:
tModel.keyframeplayer.currenttime34
the stagecolor=the stagecolor -- force a screen redraw
tDoSomethingUseful(tModel.transform)
Not real pretty since you'll have to render the entire scene again.. If
this is a problem, you can sample the animation yourself, by putting
trough a preprocess which stores transforms at say each 50ms, and then
interpolate between those.. quality well be less good though, as
you're keyframing a keyframed animation...
Good luck, Lucas

maybe this ?
update
*Syntax*
member(|/whichCastmember/|).model(|/whichModel/|).update
*Description*
3D command; causes animations on the model to update without rendering.
Use this command to find the exact position of an animating model in Lingo.
