From 485438e2be08c6d57110101f76dd41a5f484a4ee Mon Sep 17 00:00:00 2001 From: Alan Hourihane Date: Tue, 20 Apr 2004 11:13:11 +0000 Subject: add SciTech's GLDirect driver for Windows. This code is donated to Mesa which allows the usage of a Direct3D layer (DX7, DX8, DX9 or complete software fallback). No build system exists for this code yet, that will come..... --- src/mesa/drivers/windows/gldirect/pixpack.h | 108 ++++++++++++++++++++++++++++ 1 file changed, 108 insertions(+) create mode 100644 src/mesa/drivers/windows/gldirect/pixpack.h (limited to 'src/mesa/drivers/windows/gldirect/pixpack.h') diff --git a/src/mesa/drivers/windows/gldirect/pixpack.h b/src/mesa/drivers/windows/gldirect/pixpack.h new file mode 100644 index 0000000000..ec848d455b --- /dev/null +++ b/src/mesa/drivers/windows/gldirect/pixpack.h @@ -0,0 +1,108 @@ +/**************************************************************************** +* +* Mesa 3-D graphics library +* Direct3D Driver Interface +* +* ======================================================================== +* +* Copyright (C) 1991-2004 SciTech Software, Inc.
