Ayam is a free 3D modelling environment for the RenderMan interface, distributed under the BSD licence. This means that neither the author nor any contributors make money out of this software. We need your (yes your!) feedback to keep this project alive. If you use Ayam, please submit your pictures, bug reports, or comments.

Ayam currently runs on Unix (Linux, IRIX, FreeBSD tested), Win32 (Win95-Win2000, XP), and Mac OS X (Aqua and X11).

Ayam features at a glance:

* RIB (RenderMan Interface Bytestream) export and import.
* Support for NURBS curves and (trimmed) NURBS surfaces, Boxes, Quadrics (Sphere, Disk, Cylinder, Cone, Hyperboloid, Paraboloid, and Torus), CSG, MetaBalls, Patch Meshes, Polygonal Meshes, and Subdivision Surfaces.
* NURBS modelling includes approximating and interpolating curves as well as extrude, revolve, sweep, birail, skin and gordon objects with caps, holes, and bevels.
* Custom objects that may freely implement their representations (using OpenGL and RIB) and even small GUIs to edit their type specific parameters may be written by the user and dynamically loaded at runtime.
* Scripting interface: Tcl.
* Misc: instancing, arbitrary number of modeling views, object clipboard, independent property clipboard, console, n-level undo.
* File formats (r/w): RIB, DXF, 3DM, 3DMF, OBJ, X3D.
