I3D

I3D is a software tool kit designed to help you create your own interactive 3D programs in C. If you're interested in creating a program similar to Castle Wolfenstein or Ultima Underworld - I3D is for you! Applications developed with I3D may be distributed royalty-free! I3D can be used to create 32-bit MS-DOS or 32-bit Windows applications. I3D 2.1 has been tested with the Borland C/C++ v4.5, Microsoft Visual C++ v2.0, and Watcom C/C++ 32-bit v10.0B compilers. I3D 2.1 REQUIRES a 32-bit compiler and 32-bit operation system.
