Tcl3D enables the 3D functionality of OpenGL and other 3D libraries at the Tcl scripting level.


Its main design requirement is to wrap existing 3D libraries without modification of header files and with minimal manual wrapping. This is accomplished by wrapping these libraries with the help of SWIG. Tcl3D was previously called tclogl.

Sources, binaries and demos can be found on the Tcl3D website or on SourceForge . The basic version of Tcl3D is part of the BAWT Tcl-BI .

See the Tcl3D Demo of the Month page for additional demos and here on the wiki for discussion.


Two articles about Tcl3D appeared in the German Linux Magazin in 2006:

I gave the following presentations about Tcl3D at the European Tcl/Tk conferences:
