There is a new bevel mode that properly rounds to the cap surface:

The same object with slightly modified shape and simple caps:

- Dissatisfying experiments with display lists have been cancelled, instead a second set of display/drawing parameters has been introduced that is now used for interactive actions.
- Bevels on closed surfaces have been improved.
- Another example for a Script object has been added: truncated cone.
- Ayam 1.20 setup and application have been tested (and found to work ok)
on ReactOS 0.3.15. Note that the MSVC 2005 runtime from the ReactOS
software collection needs to be installed for Ayam (just like on XP).

Ayam now supports unclamping of curves and surfaces as well as extending curves to a specified point in space (adding one control point and maintaining the current shape of the curve), see this example:

Recent advances of Ayam in the CVS-Head are:- There is a new view action that zooms out to the whole scene, bound to the <Backspace> key.
- Zoom to object and Zoom to all now adjust the clipping planes and lighting parameters to facilitate working with very large (coordinate values in the range of 10.000) or very tiny (coordinate values in the range of 0.00001) objects.
- With the help of a new winding detection algorithm for 3D curves extracted from surfaces, the Bevel creation is now invariant wrt. surface winding/orientation. This means that the default bevel parameters always lead to the same bevel shape, resulting in consistent behaviour and less tweaking.
The Ayam SourceForge project has been converted to the new SourceForge platform.

X3D wire export has been extended to cover PolyMesh objects:
|
| In addition, X3D export gained a special export mode for x3dom, that embeds the scene to be exported into an existing XHTML template file. |

The Ayam team is currently evaluating the application of
x3dom
to improve the Ayam documentation and this news section with
interactive 3D-views. Those 3D-views will replace
existing 2D imagery that, naturally, always has a hard time to
convey all the information as the author intended. The replacement
will take place upon user request (as x3dom itself and the 3D assets
are a bit heavy in comparison to the simple GIF/PNG data they replace).
Possibly, pure 3D-versions of the documents will also be provided, or a
global switch to enable all 3D-views at once; this is still undecided. In the course of the evaluation of x3dom, the X3D export of Ayam was improved and a special mode for the export of NURBS surfaces was implemented. This mode allows to present models in the same way as in the Ayam view windows Shade-and-Draw display mode, i.e. a combined shaded and wireframe display of the surface, where the wires represent distinct knot values of the underlying NURBS representation. Ongoing work in this area is to extend the wire-mode to PolyMesh objects and to optimize the size of the exported X3D files. If you have a WebGL enabled browser you can try one of our first results now, by clicking on the "Toggle3D!"-button below. Note that, unfortunately, the line primitives for the aforementioned wireframe display are currently not supported by the x3dom SWF-fallback (this affects e.g. all IE users).

Here is some help on the keyboard commands and mouse bindings in x3dom.
If it did not work at all (this is not unexpected), maybe a visit to the x3dom browser check brings some enlightenment.
