OVERVIEW of '3Dtools'
--- in the FE 'tkGooies' system :

A description of the FE 'tkGooies' system is available via a 'tkGooies' Description page. That page points out that the 'tkGooies' are a collection of utilities in categories such as

  • 3Dtools
  • AUDIOtools
  • FILEmanagers
  • IMAGEtools
  • INTERNETtools
  • MATHtools
  • PLOTtools
  • SELECTORtools
  • SYSTEMtools
  • TEXTtools
  • VIDEOtools
  • Tk-GAME menus
  • Tk-WIKI demos
  • MORE

Just below is a list of links to pages that present the source code of a growing collection of the '3Dtools' in the FE 'tkGooies' system ... that is, growing provided I keep growing older.
