GFXLIB demos banner (640x128 GIF)

 

The demos on this page are intended to show what can be achieved with GFXLIB, an extensive library of graphics functions for BBC BASIC for Windows (a.k.a. BB4W).

Click here to go to the GFXLIB Homepage. GFXLIB can only be used with the full version of BBC BASIC for Windows.

 

You do not need to have BBC BASIC for Windows or GFXLIB installed on your computer in order to be able to run these demos.
You should be able to run the EXE (executable) files directly from within the ZIP folders (you shouldn't have to ‘extract’ the EXE files first!).

Source code downloads marked with a red asterisk (*) indicates that a version of GFXLIB higher than that which is currently publicly available is required
to run the source code. Sorry for any inconvenience that this may cause!

Xmas demo II This short, multi-part demo was released Christmas 2009. Most of the graphical effects are achieved with GFXLIB, except the 3D snowman part which uses D3DLIB (BB4W's standard Direct3D library). The source code isn't available for download because I seem to have lost it! 5.69 MB Download - -
