Volumes
From CPCWiki - THE Amstrad CPC encyclopedia!
Volumes is a BASIC type-in from Science & Vie Micro (SVM) 9/86 that creates images of rotationally symmetric 3-D objects (like glasses, etc.) with shading and hidden surface removal.
The program only works on a CPC464 without the AMSDOS ROM because it pokes some data and machine code into the AMSDOS jump block area.
