3D Artwork with ConTeXt
by Renaud AUBIN 29 Sep '06

29 Sep '06

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

transparent metafun colors turn nearly black
by Sanjoy Mahajan 29 Sep '06

29 Sep '06

Just for (meta)fun, I tried a few experiments with transparent colors. The example below gives a black circle instead of a red one. Is it that transparent colors aren't part of metafun -- which I can easily live with since color printing is too expensive still, alas -- or have I omitted an essential command? ==================== cut here ==================== \runMPgraphicstrue \setupcolors[state=start] \starttext \startreusableMPgraphic{a} % _inline_specials_ := true; % had hopes for this line, but no luck % next line taken as an example from mp-spec.mp fill fullcircle scaled 10cm withcolor transparent(8,.3,red); \stopreusableMPgraphic \placefigure[force,none]{}{\reuseMPgraphic{a}} \stoptext ==================== cut here ==================== The metapost output (testfile-mpgraph.1) always contains the following color setting, no matter what arguments I pass to transparent() : 0.123 0.003 0.001 setrgbcolor Which is close to black. (This is all with ConTeXt 2006.08.08. The live ConTeXt gives a square saying "undefined".) -Sanjoy `A society of sheep must in time beget a government of wolves.' -- Bertrand de Jouvenal

The other day I was just searching for Context books on Amazon and all over the web. I have bought 5 LaTeX books a few years ago and I was expecting to find some Context books. Also, some of the Context manuals are still unfinished. Specially the ones about style and layout. I liked those manuals very much, but too bad they are incomplete. I was looking for some book about that. Fidel.

MPenvironment ignored for btex..etex (or should I use sometxt)?
by Sanjoy Mahajan 29 Sep '06

29 Sep '06

I'm not sure what's going on here, but this file fails (2006.09.28 beta): [well I have a better idea now after writing out the whole email, see the end...] =================== 3.tex ================= \starttext \startMPenvironment \def\2{hello} \stopMPenvironment \startreusableMPgraphic{fig} label(btex \2 etex, origin); \stopreusableMPgraphic \reuseMPgraphic{fig} \stoptext ========================================= The error is (from 3.log): ============== error snippet =============== systems : begin file 3 at line 1 color : currentcolor (def) is not defined \openout7 = `3-mpgraph.mp'. ! Undefined control sequence. <argument> label(btex \2 etex, origin); \writecheckedMPgraphic ...icfalse \edef \ascii {#1 }\convertcommand \ascii \t... \startMPgraphic ...hic \writecheckedMPgraphic {#1} \stopwritingMPgraphic \handlereusableMPgraphic ...phic #3\stopMPgraphic \doifobjectssupportedelse ... \douseMPgraphic ...s [#1][#2]\getvalue {\@@MPG #1} {}\elabelgroup <to be read again> l.10 \reuseMPgraphic{fig} ? R etc. ============== error snippet =============== But 3-mpgraph.mp (produced after giving 'R' to enter nonstopmode) looks fine: =============== 3-mpgraph.mp ================ <lots of stuff> beginfig(1); verbatimtex \global \loadfontfileoncetrue \def \2{hello} etex; label(btex \2 etex , origin); ; endfig; let end=mprunend; end. =============== 3-mpgraph.mp ================ It processes by hand fine: $ mpost -mem=metafun 3-mpgraph ... 1 output file written: 3-mpgraph.1 (or by using the system(texmfstart ...) command in 3.log) Oh, wait, if metapost is fine with the file but ConTeXt isn't, then the error above must be from ConTeXt parsing the metapost code and seeing the \2, then complaining. So am I supposed to use the global option to \startMPenvironment? If it's needed in this case, I think it would be needed in every case (ConTeXt would see all the metapost uses of the definition). Or is btex deprecated and I should use \sometxt (except in loops)? Or am I just confused?! -Sanjoy `A society of sheep must in time beget a government of wolves.' -- Bertrand de Jouvenal

Texts after typing environment
by Zhichu Chen 28 Sep '06

28 Sep '06

Hello everybody, If I type: ------------------------------------------- \starttyping some verbatim texts \stoptyping -------------------------------------------- does ConTeXt treat it as a complete paragraph? In LaTeX, when I type: -------------------------------------- \begin{verbatim} some texts here \end{verbatim} some other texts \begin{verbatim} some texts here \end{verbatim} other materials --------------------------------------- The output will be --------------------------------------- some texts here some other texts some texts here other meterials -----> This line is indented !! ---------------------------------------- What should I do in ConTeXt? I really want to control this. but whether I leave a blank line after \stoptyping or not, nothing changed. Have I expressed my problem clearly? yours, chen

Layer Question
by Tobias Burnus 28 Sep '06

28 Sep '06

Hello, I would like to add a text to a poster, which I load as PDF. The following works nice, except that the layer of the PDF is above the layer "block" thus the text gets overdrawn. How can I change that order? Tobias \setuppapersize[A0,landscape][A0,landscape] \setupbodyfont[26pt] \setuplayout[backspace=0cm,width=fit,height=fit,margin=0cm,topspace=0cm,header=0cm,footer=0pt] \definelayer[block][width=85mm,height=54mm] \setupbackgrounds[page][background=block] \starttext \startstandardmakeup \combinepages[poster.pdf][nx=1,ny=1] \setlayer[block][x=10cm,y=10cm]{\copyright 2006} \stopstandardmakeup \stoptext
