+
+ WindML Driver for Mesa 3.5
+
+
+Requirements
+------------
+
+Tornado 2 + WindML, Cumulative Patchs are recommended.
+
+I suppose you have a valid WindML installation. Double buffer hardware
+gives better performance than double buffer software so if you can
+compile your WindML driver with this option, just do it. I/O
+redirection is adviced in target server.
+
+Tested on
+---------
+
+During the development, my main target was a CoolMonster:
+- Video card: CT69000
+- CPU: PENTIUM 266MHz
+
+and my host a Windows NT + Tornado 2.
+
+
+Installation
+------------
+
+1. Mesa sources must be in root directory (C:\)
+
+2. Add the following line to your torVars.bat:
+set MESA_BASE=C:\Mesa
+
+OR copy the new torVars.bat in your bin path:
+c:/Mesa/src/ugl/tornado/torVars.sample ->
+/mnt/nt/Tornado/host/x86-win32/bin/torVars (for example)
+
+3. In a command prompt:
+$ torVars
+$ cd c:\Mesa
+$ make -f Makefile.ugl CPU=PENTIUM
+
+Take a long while...
+
+5. Include all the files from ugldemos folder to build some downloadable
+ application modules
+
+4. Download UGL/Mesa object files on target
+
+For example via the WindShell:
+ld < c:\Tornado\target\lib\objMesaGL.o
+ld < c:\Tornado\target\lib\objMesaUGL.o
+ld < c:\Tornado\target\lib\objMesaGLU.o
+ld < c:\Tornado\target\lib\objGLUTshapes.o
+ld < c:\Tornado\target\lib\objMesaOS.o
+
+6. Download the application modules.
+
+7. In WindShell, run:
+-> uglalldemos
+
+During the show some messages will appear, it provides some useful
+information on key management.
+
+
+Coding
+------
+
+Sample Usage:
+
+In addition to the usual ugl calls to initialize UGL, (may be find an
+input driver), you must do the following to use the UGL/Mesa interface:
+
+1. Call uglMesaCreateContext() to create a UGL/Mesa rendering context,
+ given the display format.
+
+2. Call uglMesaMakeCurrent() to bind the UGL/Mesa buffers to an
+ UGL/Mesa Context and to make the context the current one.
+
+3. Make gl* calls to render your graphics.
+
+4. Use uglMesaSwapBuffers() when double buffering to swap front/back buffers.
+
+5. Before the UGL is destroyed, call MesaDestroyContext().
+
+6. Before exiting, call if required uglEventQDestroy and then uglDeinitialize();
+
+Limitations
+-----------
+
+I found the following limitations in my driver :
+ - Color Indexed management is only in 8 bits
+ - The front and the back buffer must have the structure (mode and
+ size). A structure umc->buffer is requisite if the front and back
+ buffers are different.
+ - It isn't possible to mix UGL/OpenGL application with a software
+ double buffer (to fix)
+

+ * WindML driver (Stephane Raimbault)
+ *
+ * Revision 1.5 2000/12/24 22:53:54 pesco
+ * * demos/Makefile.am (INCLUDES): Added -I$(top_srcdir)/util.
+ * * demos/Makefile.X11, demos/Makefile.BeOS-R4, demos/Makefile.cygnus:
+ * Essentially the same.
+ * Program files updated to include "readtex.c", not "../util/readtex.c".
+ * * demos/reflect.c: Likewise for "showbuffer.c".
+ *
+ *
+ * * Makefile.am (EXTRA_DIST): Added top-level regular files.
+ *
+ * * include/GL/Makefile.am (INC_X11): Added glxext.h.
+ *
+ *
+ * * src/GGI/include/ggi/mesa/Makefile.am (EXTRA_HEADERS): Include
+ * Mesa GGI headers in dist even if HAVE_GGI is not given.
+ *
+ * * configure.in: Look for GLUT and demo source dirs in $srcdir.
+ *
+ * * src/swrast/Makefile.am (libMesaSwrast_la_SOURCES): Set to *.[ch].
+ * More source list updates in various Makefile.am's.
+ *
+ * * Makefile.am (dist-hook): Remove CVS directory from distribution.
+ * (DIST_SUBDIRS): List all possible subdirs here.
+ * (SUBDIRS): Only list subdirs selected for build again.
+ * The above two applied to all subdir Makefile.am's also.
+ *
+ * Revision 1.4 2000/09/08 21:45:21 brianp
