If I look (today) at the first page in the Gallery of examples: https://asymptote.sourceforge.io/gallery/ I no longer see the links to the code of the pictures. If I look at other pages (2d graphs etc) I see the links. Is this only me? Maurizio

I attach a screenshot of the original pdf.

Now I realize something strange is happening here. I attached a pdf to my previous answer. The pdf I see and which I uploaded from my mac is different from the pdf I see if I download the attached picture and I look at it (with the same viewer). Indeed, I no longer see a part of it (I no longer see the tube but only the part with the 2d segment). How is that possible? I add that the pdf I have on my mac was sent to Springer and a book was printed (2 or 3 years ago) with that picture appearing on...

Yes, basically I wanted to combine 2d and 3d output, in order to be able to use in some 3d context my macro "drawshifted" which is basically a 2d tool, but which I found useful in some 3d situation. I attach a picture which some years ago I was able to create in this way. The path with the $s$ clearly denotes the abscissa of the point where the tube ends. I got that by "drawing shifted" the path on which the tube is based. Now I am in the situtation in which I need to edit and slightly modify a bunch...

In the following .asy file if I uncomment line A I no longer get the "tube" otherwise created by the last line. Can anyone tell me what the problem is? Is there some incompatibility? Thanks Maurizio import three; import tube; import graph3; currentpicture=new picture; unitsize(10cm); currentlight=White; triple P(real t){return (0,t,0);} path3 segment=graph(P,-1,1); path segmentprojected=project(segment); draw(segment,linewidth(.2)); //draw(segmentprojected); //A draw(surface(tube(segment,scale(0...

Thanks!!! However my situation is still not clear, and perhaps of interest to someone else. I searched for libgs.so (which on MacOs, is named libgs.dylib, as I learned) and I found it: /System/Volumes/Data/opt/homebrew/lib/libgs.dylib /System/Volumes/Data/opt/homebrew/Cellar/ghostscript/10.03.1/lib/libgs.dylib /opt/homebrew/lib/libgs.dylib /opt/homebrew/Cellar/ghostscript/10.03.1/lib/libgs.dylib I also added a path to it: LIBGS="/opt/homebrew/lib/libgs.dylib" just to make sure. Thus, I assume that...

I am on MacOS Sonoma and Asymptote 2.91 I do not understand why compiling a certain .asy file with options -f html I get processing of PostScript specials is disabled (Ghostscript not found) WARNING: 2 PostScript specials ignored. The resulting SVG might look wrong. I have file: /Users/maurizio/.asy/config.asy with content: import settings; gs="/opt/homebrew/Cellar/ghostscript/10.03.1/bin/gs"; and I have gs with the following path /opt/homebrew/Cellar/ghostscript/10.03.1/bin/gs Why gs is not found?...

I am no longer on Win, but for years and years I have been on Win with Miktex and Asymptote (downloaded from SourceForge) and never had any issue.
