  • The perp vector calculation in the solids module was fixed. A bug in the
  • mouse motion functions was fixed. A pan action (which differs from shift
  • due to perspective distortion) was added to the OpenGl renderer;

  • mouse button mouse binding was changed from "zoom/menu" to "zoom".
  • User-initiated exports no longer cause the renderer to quit.
  • Dynamic time stepping was fixed in the ode module; the "integrate"
  • routines now return the array of computed values. Operators == and != were
  • added for all built-in arithmetic 2D arrays; a segmentation fault was
  • fixed. The etc/fstab kludge for Cygwin 1.7 was removed. The configuration
  • directory under TeXLive is now $TEXMFCONFIG/asymptote.

New in Asymptote 1.78 (Jul 4, 2009)

  • drawing thick curved lines. A bug in FSAL ODE integrators when using a
  • fixed time step was fixed. Missing miterlimit defaults were added.
  • Xasy was updated to use Python 2.6.2 and Imaging-1.1.7b1 (which requires no
  • alpha support patches). Obsolete patches were removed. More TeXLive build
  • issues were addressed: the install-prebuilt target omits texhash and does
  • not attempt to install PNG files for asymptote.info. A configuration
  • problem with --disable-gc was fixed. The 3D mouse bindings are now
  • customizable. Support was added for generating syntax highlighting for the KDE
  • editor Kate.

  • splined surface routines was fixed. An ode module for solving ordinary
  • differential equations was added. A bug in maxtimes and mintimes was fixed.

New in Asymptote 1.76 (Jun 6, 2009)

  • A bezulate bug was fixed. The resolution and caching of texpath were improved; for PDF tex engines, the basealign pen attribute is now respected. Support for OCG layers was added. Lights Headlamp and White were implemented; the predefined adobe light was removed. Holes are now handled
  • in superpath-to-surface constructor when planar=true. A degenerate transform3 issue was fixed. The alignment of rendered and PRC images was improved; the angle for rendering absolute projections was fixed. Inaccurate TeX and ConTeXt font scalings were fixed. A texsize(string, pen=currentpen) function returns the raw TeX dimensions {width,height,depth}. A new version of asymptote.sty (1.07) fixes attach=true mode.

New in Asymptote 1.75 (Jun 2, 2009)

  • Issues with 3D labels and texpath, both in inlinetex mode and with the
  • ConTeXt TeX engine, were resolved. A bug in bezulate was fixed. A partial
  • workaround was added for the unimplememented -output-directory ConTeXt
  • option (the current directory must still be writeable). The aspect ratio
  • and viewportmargin calculation in module three was improved, with tighter
  • 3D bounds. A bug in the intersectionpoints(path3, surface) routine was fixed.

New in Asymptote 1.70 (Apr 11, 2009)

  • A labelpath3 module for typesetting curved labels in 3D, contributed by Jens
  • Schwaiger, was added. PenMargin2 was defined for use with planar arrowhead
  • types like DefaultHead2. A center=false parameter was added to projections
  • to allow one to automatically center the target within the bounding volume.
  • The ambiguity in the surface function was resolved. Problems with spaces in
  • filenames were fixed.

New in Asymptote 1.69 (Apr 6, 2009)

  • Internal patch degeneracies were removed by splitting. Bugs in the
  • windingnumber and the intersection routines were fixed. The inside(path)
  • routine was improved; a fillrule argument was added. The bezulate connect
  • routine was improved. Bezulate is now automatically applied to path arrays:
  • surfaces should be constructed directly, without first calling bezulate.
  • A workaround for recent changes in the hyperref package was implemented.
  • The divisor setting was replaced with purge(divisor=0). The calls to baseline
  • in graph.asy were fixed. A miterlimit attribute was added to pens.
  • Animation problems were fixed. Lighting problems with multiple exports and
  • a quit deadlock were fixed. A new version of asymptote.sty (1.06) fixes
  • an undefined ASYbox.

New in Asymptote 1.67 (Mar 20, 2009)

  • Spurious annotation question marks in 3D PDF attachments were fixed;
  • attached images are now printable.
  • The asy environment defined in the new (1.04) version of asymptote.sty supports keyval options width, height, viewportwidth, viewportheight, and attach; the obsolete asyattach environment was removed.
  • The default viewportwidth is the linewidth in inline mode and 0 in attached mode. Planar projected arrows were fixed.
  • Automatic camera adjustment was improved. A minimum viewportsize can now be specified.
  • The control points for cyclic segments produced by texpath were
  • fixed.
  • Overlap issues in planar surface patches were fixed.
  • Surface constructors were simplified: the routine planar has been replaced by
  • surface(path, triple plane(pair)=XYplane) and in most cases there is no
  • need to call bezulate directly.
  • An Align constant was added.
  • The parameter limits used in buildcycle were fixed.
  • The intersection routines now respect the fuzz parameter.
  • Segmentation faults involving null cyclic guides were fixed.
  • Subpath now preserves the straight flag.
  • Pictures containing graphs now transform correctly; unextended axes limits and tick selection were improved.
  • Axial and radial shading respect now respect -gray.
  • The animation prefix was fixed.
  • An example of drawing a surface from irregular data was added.
  • A work around was implemented for an intermittent hang on exit in the 3D native renderer. An auto3D option was added for controlling the poster option.
  • The 2008/10/08 version of movie15.sty is now compulsory.
  • The cd %USERPROFILE% command was removed from asy.bat.

  • M /trunk/asymptote/settings.cc
  • M /trunk/asymptote/settings.h

  • Outputting PDF format to other directories was fixed. An int hex(string) function that casts a hexidecimal string to an integer and a pen rgb(string) routine that returns a pen corresponding to a given 6-character RGB hexidecimal string were added.
  • In the dot routines, Label arguments were added and minor bugs were fixed. A parametric version of
  • markuniform was added.

New in Asymptote 1.40 (Jan 8, 2008)

  • Hatch widths for PDF output were fixed by disabling dynamic line width adjustment.
