Laminar Research on theX-Plane (simulator) [cite web |url=http://scenery.x-plane.com/tutorials.php?doc=ac3d |title=X-Plane 8 Scenery Tutorials |accessdate=2007-11-22 ] . The .ac format has also been used inFlightGear for scenery objects and aircraft modelsHistory
Initially developed on the
Amiga , the code was then ported to Silicon Graphics workstations which used the GL graphics library. At that time, the user interface was implemented using X-Window/Motif. A Linux port was released onto the internet in 1994 (the GL graphics were replaced with OpenGL). A windows port followed when the X-Window interface was dropped in favor of the portableTcl /Tk scripting library.In 2002 Inivis Limited purchased the full intellectual property rights to AC3D and continues to develop and market the software. They decided to keep the name AC3D for the software.
In 2005, a Mac OS X version of AC3D was released.
Modeling
AC3D's modeling is polygon/subdivision-surface based. Unlike some other 3D software, AC3D refers to 'surfaces' rather than 'polygons'. An AC3D surface can be a polygon, polygon-outline or line. An AC3D object is a collection of surfaces.
3D files
AC3D can load and save a wide variety of 3D file formats but primarily uses its own .ac file format which is ascii.
Inivis is the first 3rd party vendor to offer officially sanctioned support for the
Second Life sculpted prim format; exporters for other 3D software packages exist, but are solely user-supported. [cite web |url=http://wiki.secondlife.com/wiki/Sculpted_Prims:_3d_Software_Guide |title=Sculpted Prims: 3d Software Guide |accessdate=2007-11-22 ]cripting and plugins
Extra functionality can be added to AC3D via Tcl/Tk scripts and/or C/C++ dynamic libraries (plugins). A software development kit (SDK) is available to licensed users.
