New in the CVS head are C1 fillets for concatenated curves, see the following screenshot for an example and comparison with the old G1 fillets (blue curve) which continue to be available of course:

G1 vs. C1 Fillets (click for larger version)

As you can see in the lower right corner, the shading for the C1 fillets changes more smoothly to the corner (i.e. it is hard to say where the fillet actually begins), however, the corner itself has a somewhat higher curvature. As the shape of the fillet is completely controlled by the C1 condition, smoother corners could only be achieved by moving the respective end points of the concatenated curves further apart.

Welcome back 3D-bevels:

1. Oct 2012

Some property GUI user interface elements have been redesigned (default menu buttons and parameter value changing buttons no longer use text labels, menu entries layout improved on Aqua):

30. Sep 2012

Introducing object search that allows to search for objects given criteria, like e.g. names, types, materials, property values, master-instance relationships, or return values of arbitrary commands/procedures. The found objects can just be highlighted in the object tree, or arbitrary commands can be executed on them:

The list of frequently asked questions (FAQ) has been updated.

Recent advances in the CVS-Head:

There are now two new cap creation modes, simple and simple integrated. Both work with non-planar curves, but can not cope with concave input. The integrated variant is combined into the capped surface via the concat surface mechanism.
Also bevels can now be integrated into the respective parameter surfaces.
As many tool objects now get the capabilities for bevel/cap creation on all four sides, the increased number of options to control bevels and caps are placed in new property GUI sections.
For easier management of properties, there is now a dialog that helps in creation/removal of NP/RP tags.

Recent advances in the CVS-Head:
There is now a plugin that supports scripting in the Lua scripting language.
Similar to the JavaScript plugin jsinterp, the new luainterp plugin defines a Tcl command to run Lua code (luaEval), wraps the Ayam scripting interface commands as functions (e.g. crtOb()) and additionally defines the functions tclvar(), tclset(), and tcleval(). Lua code can, of course, also be run in Ayam Script objects:

The Ayam 1.20 Linux release archives and setup executables have been updated with a statically linked ayslx plugin (compiled with Aqsis 1.8.1).

31. Mar 2012

Here is what is planned for the next release of Ayam (1.21):

improvement of section placement in Sweep, Birail1, Birail2, and Clone objects for trajectory curves with multiple knots/control points (preserving sharp corners and linear sections),
faster NURBS display while modelling or view actions are active through employment of display lists,
support for degenerate surfaces for OffsetNP,
selection mechanism for faces and lines to improve Subdivision-NURBS modelling,
custom bevels for all tool objects (not just for the Bevel object),
improved draw/shade quality of quadrics,
Lua scripting language integration

Ayam 1.20 has been released. Get the new version from the download page, see also the complete list of changes.

21. Mar 2012

Ayam 1.20 preliminary installer executables for the Linux and Win32 platforms are now available for pre-release testing purposes on request.

19. Mar 2012

A feature freeze for the next official release, Ayam 1.20, scheduled for mid to end april is in effect as of today. The version of the CVS-Head has been bumped accordingly and interested parties may download and test Ayam to find bugs before release.

2. Mar 2012

Fillets and custom knots are now available to ConcatNP in the CVS-Head. A simple experiment with two quadrics, a half torus and a cylinder, leads to this piping, the smooth transition is created automatically:
