Je rappelle que le forum n'est pas adapté pour y compiler des exemples 3D.
Pour évoquer de tels exemples, il faut se contenter de fournir le code entre des balises codes et non des balises asy.

Bonjour,

Je viens de réaliser que le numéro de version d'Asymptote n'apparait plus correctement lors de la création d'une figure Asymptote sur le forum.

Cela tient au fait que la commande "asy -version" ne renvoie plus simplement une ligne telle que celle-ci

Code : Tout sélectionner

Asymptote version 2.67-66 [(C) 2004 Andy Hammerlindl, John C. Bowman, Tom Prince]

mais qu'elle est complétée par plusieurs lignes d'informations (les options activées et désactivées) :

Code : Tout sélectionner

Asymptote version 2.67-66 [(C) 2004 Andy Hammerlindl, John C. Bowman, Tom Prince]

ENABLED OPTIONS:
GSL      GNU Scientific Library (special functions)
FFTW3    Fast Fourier transforms
XDR      external data representation (portable binary file format)
Readline interactive history and editing
GC       Boehm garbage collector

DISABLED OPTIONS:
WebGL    3D HTML rendering
OpenGL   3D OpenGL rendering
Sigsegv  distinguish stack overflows from segmentation faults

Au lieu de prendre les 19ème à 22ème caractères de la première ligne "Asymptote version 2.67-66 ...",
cela récupère les 19ème à 22ème caractères de la dernière ligne "Sigsegv distinguish stack ..."
donc au lieu de lire "Asymptote 2.67" au dessus de l'image, on lit actuellement "Asymptote sh s"

Vérification que l'ajout d'un grep 'version' au bon endroit rectifie correctement le problème soulevé ci-dessus.

Version 2.67 du 06/08 : https://sourceforge.net/projects/asymptote/files/2.67/

• Support was added for importing and inputting URLs.
• Compilation and 2D SVG to HTML conversion no longer requires the GLM library; 2D html output is fit to the canvas unless settings.absolute=true.
• Diagnostics for dvisvgm were enabled; SVG clipping was fixed.
• A -globalread setting (default true) was implemented.
• Files are opened using the search path, which now includes the examples directory.
• An invalid array dimensions error was fixed.
• A WebGL resize event listener was added; the + and - keys now zoom in and out, rather than expanding and shrinking the viewport.
• Remeshing on export is forced; unnecessary remeshing on zoom in AsyGL is avoided.
• The triple dir(path3, path3) function was normalized.
• The repositioning of OpenGL windows was fixed.
• The copy constructors for path and path3 were fixed.
• Asymptote errors no longer cause Xasy to hang.
• A numerical precision issue was fixed.
• A portable way of skipping whitespace was implemented; casts from empty strings now yield uninitialized values.
• Interrupt handling under MacOS X was fixed.
• A devicepixelratio setting was implemented.
• The error location is displayed in the console.
• Segmentation faults were fixed.
• The documentation was updated and the code was reformatted.
• A hang on exit under MSWindows was fixed.
• Obsolete encoding modules were removed.

Version 2.69 du 20/02/2021 : https://sourceforge.net/projects/asymptote/files/2.69/

• A segmentation fault in subpath3 was fixed.

• Orthographic scaling is now consistent with perspective scaling when keepAspect=false.
• The obsolete everypage package was removed.

Version 2.70 du 30/03/2021 : https://sourceforge.net/projects/asymptote/files/2.70/

• A stack overflow was fixed.
• Under MSWindows, problems with SVG generation and Xasy installation were fixed.

Version 2.71 du 25/12/2021 : https://sourceforge.net/projects/asymptote/files/2.71/

• Support for the portable compressed 3D vector file format V3D was added.
• The default value of settings.prc was changed to false.
• Efficient order-independent transparency was implemented for modern OpenGL platforms and the OSMesa offscreen rendering engine (with no interactive transparency support for Mac OS X and WebGL).
• The WebGL library now uses WebGL2 if available.
• Image-based lighting was implemented.
• Many bug fixes and improvements were made to Xasy, allowing objects drawn with the graphical editor to be saved to and restored from a .xasy file, as well as being exportable to an .asy file.
• A function was added to graph a parametric function with control points determined by the specified derivative.
• The recommended PostScript viewer for MSWindows is now Sumatra PDF.
• The workflow for generating transparent PDFs and PNGs was fixed.
• Emacs lasy-mode was patched to work with Emacs >= 23. Support for the Language Server Protocol was added.
• Compilation with COMPACT=0 is supported again.
• All threads now return the same error code.
• A remote command-line interface to http://asymptote.ualberta.ca is now available.

Version 2.72 du 27/12/2021 : https://sourceforge.net/projects/asymptote/files/2.72/

• WebGL2 is enabled by default only for examples that use image-based lighting.
• Multiple output formats in threaded interactive mode are now handled correctly.
• CPU partial sum indexing is used in the 3D transparency shader if the compute shader fails to compile.

Version 2.73 du 27/12/2021 : https://sourceforge.net/projects/asymptote/files/2.73/

• The asygl library was updated to support embedding of WebGL and WebGL2 scenes on the same page.

Suite à un problème relatif à inlinetex, signalé par un utilisateur, John Bowman fait une suggestion en attendant la 2.74 :

Thank you for the clear explanation of the problem and solution. Users can wait for the 2.74 release or update three.asy now:
https://raw.githubusercontent.com/vecto ... /three.asy
