Another missing feature? (All I want for Xmas...)
It doesn't seem to be possible to show some kind of nameplate in the corner
of a picture that stays put when the design is rotated or moved about. That
would be useful for the name of the design, author, date/version etc.
Shouldn't be that difficult?

BTW Does this forum do animated .gifs?

You can use these variables
https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Other_Language_Features#$vpr,_$vpt,_$vpf_and_$vpd
to make something face way you want.

OpenSCAD Admin - email* me if you need anything, or if I've done something stupid...

I do:
https://de.wikipedia.org/wiki/Benutzer:MichaelFrey#3D-Animationen
https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Example/Strandbeest
For the purpose of commons/wikipedia, watermarking is not well liked.
I rarely publish the code of the animation, as I feel like I have to
polish the code before publication.
(as seen with the Strandbeest Example)
The 2D animations are in javascript - that code has become impossible to
publish, as I use messy copy paste code.
One tip I like to give: For high quality render, you can use OpenSCAD to
create STL Files, which then can be animated and rendered in POV-Ray.
The result of my test looked like this:
https://commons.wikimedia.org/wiki/File:Question_Mark_3D_Animation_POV-Ray.gif
https://de.wikipedia.org/wiki/Benutzer:MichaelFrey#/media/Datei:Strandbeest_POV-Ray_3D.gif
I Love the transparency of the GIF and the possibility to use textures,
but creating a stable rendering chain requires three seperates pieces of
code (OpenSCAD for creating the STL File, POV-Ray to import, rotate and
render, Bash Script to glue it together). POV-Ray is a power full
language in its own right, but OpenSCAD is easier to learn and easier to
model with, easier to animate with, so the POV-Ray strandbeest, I used a
script to generate each leg position in OpenSCAD and export it to STL.
All the POV-Ray script does is instantiate 6 legs in the correct angle
and rotate and position them.
With Kind regards,
Michael Frey
You can use these variables
<https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Other_Language_Features#$vpr,$vpt,$vpf_and_$vpd>
to make something face way you want.
So the possibility does exist. That's good to know. I had previously
stumbled across the section on $vpr, $vpt, $vpf and $vpd in the User Manual
but it talks about moving the viewport, whereas I want to fix an object I
have created. My viewport (PC monitor) is fine where it is on my desk and
moving it would not help anyway, I thought, and moved on.
Now, "Moving the viewport does not update them" sounds promising but there
is unfortunately no indication of how to actually fix one object in a
particular position while leaving the rest free to move.
So the next question is: How are $vpr, $vpt, $vpf and $vpd used to fix an
individual object in the lower right corner of the display? Could you give a
code example?

Some very nice animations!
You would probably like Charles Parsons' steam engine of 1877.

Here is one for inspiration to get you started.
// turn on animation
$vpr = [$vpr[0], 0, $t * 360]; // animated rotate around Z
echo($vpt=$vpt,$vpr=$vpr,$vpd=$vpd); //,$vpf=$vpf);
// object of interest
cube([75,20,50]);
// oriented message
translate([25,25,100])
rotate([$vpr[0],$vpr[1],$vpr[2]])
text(str("$vpr=",$vpr[2]),size=10);

That had some line break problems in the email, check the forum to get the
right one.

So it's got some built-in errors, right?

Not sure what you mean?
Every so often emails from the forum lose line breaks, I don't know where it
happens.
e.g. This is what I got:
// turn on animation
$vpr = [$vpr[0], 0, $t * 360]; // animated rotate around Z
echo($vpt=$vpt,$vpr=$vpr,$vpd=$vpd); //,$vpf=$vpf); // object of interest
cube([75,20,50]); // oriented message
translate([25,25,100])
rotate([$vpr[0],$vpr[1],$vpr[2]])
text(str("$vpr=",$vpr[2]),size=10);

...an of course, that quote has different breaks...
I suspect it may be my email client, this is what I got.
