Hi all,
I'm now playing with u3d and since I'm at rookie level in ConTeXt dev, I
have (a lot?) of questions for you.
First, download http://www.nibua-r.org/ConTeXt/devel/3dartwork.tgz and
"texexec test-3dartwork". Since I use \externalfigure and u3d mean
nothing to ConTeXt, I obtain
TeXUtil | running texmfstart rlxtools --identify ./context.u3d
identify: no decode delegate for this image format `./context.u3d'.
RlxTools | unable to identify ./context.u3d
Ok, this is normal... I used \placefigure and \externalfigure for
convenience for the moment since I found natural to use them... How to
bypass RlxTools ?
Now, see t-3dartwork. There is a lot of work. The main idea is to split
\doPDFinsertiiidartwork into several macros ;) . I need help on:
1. What's the best way to define the following macro
\defineiiidartworkprojection[name][type=perspective|orthographic ,
nf=automatic|explicit , near=number, far=number, fov=number.....]
You're welcome to give your opinion on naming convention ;)
2. Same question for
\defineiiidartworkview[name][bgr=number, bgg=number, bgb=number (or 3
floats for bgcol), projection=name, camera= 3 floats (but how?), target=
idem, up=idem]
I'll use ruby and a magic | (see [NTG-context] run a ruby script and use
the standard output ???) to calculate C2W and CO...
3. ... I need to define a macro to setup the 3D annot before to use it
by \externalfigure or with another brand new macro...
That's it for the moment...
Renaud

hm, maybe we need a feature to mark a category as non-rlx-able
for the moment use \chardef\figurerlxmode\zerocount
it's comparable to movies and so, as long as some kind of dimensions are
known ... i'll look into that later

try to use existing ones: auto instead of automatic

best is to make that pluggable, so that we can optimize such computations

just collect whatever we need to do that and i'll integrate it in such a way that multiple backend are supported as well as mkii and mkiv code

Dimensions are not known explicitly from the 3D Artwork.
\useexternalfigure allows us to set height and width as desired.
Moreover, for a given width, different height doesn't affect the aspect
of the 3D Artwork.

What do you mean by "pluggable" ? Do you mean that we can turn this
"feature" on or off ? (for the moment, it's definitely off ;) )

something:
CW2=\defaultcwii
where we can implement \defaultcwii as we want, but at the same time
(for the moment) you can set it manually
