Date: 30 Jul 1995 02:26:55 GMT Organization: Department of CompSci, U. of Waikato, New Zealand. Lines: 16 Nntp-Posting-Host: mercury.cs.waikato.ac.nz Summary: how to frame buffer? Keywords: GRX To: djgpp AT sun DOT soe DOT clarkson DOT edu Dj-Gateway: from newsgroup comp.os.msdos.djgpp Hi there! I'm porting a graphics intensive program to the pc, using djgpp at the moment. I have the 1.03 GRX lib, which works ok. We currently save the current context, and extract the video base memory in order to write directly to it. This is sufficiently fast, but obviously we really need to use frame buffering, ie, write to a context not visible, then switch this to be the displayed one. How do we do the switching?? Sorry if this is a dumb question, the docs don't seem to cover it. Thanks, Steve sfd AT cs DOT waikato DOT ac DOT nz
