LibGGI driver for Mesa-3.0
by Uwe Maurer (uwe_maurer@t-online.de)
Introduction
============
[from libggi.txt by Steve Cheng and Hartmut Niemann]
"LibGGI, the dynamic GGI (General Graphics Interface) library is a
flexible drawing library.
It provides an opaque interface to the display's acceleration
functions. It was originally intended to allow user programs to
interface with KGI, the kernel side of the GGI code, but other display
types can be easily used by loading the appropriate "display target"
(e.g. X, memory).
LibGGI consists of a main library (libggi.so) and a multitude of
dynamic drivers. The library then loads the necessary "drivers" for
the requested mode, taking hints from the graphics device if
necessary. LibGGI can also load extension libraries, e.g. to provide
enhanced 2D and 3D functions.
It has been designed after having a look at several existing
libraries, and so far we have found porting to be quite simple from
and to most of them."
----------------------------------------------------------------------------
More information about the GGI project and LibGGI can be
obtained from the GGI website:
www.ggi-project.org
----------------------------------------------------------------------------
Installation
============
- Install LibGGI
- Unpack the Mesa archives
- In the Mesa directory type:
make linux-ggi
su
make linux-ggi-install
exit
- Now you can try some demos.
If they don't work, you can set the GGIMESA_DEBUG
variable to 255 and you will see some information from the
LibGGI-driver.
export GGIMESA_DEBUG=255
GLUT
====
You can change these default values in ggi/ggiglut.c:
#define WIDTH 640
#define HEIGHT 400
#define GRAPHTYPE_RGB GT_16BIT
#define GRAPHTYPE_INDEX GT_8BIT
Options:
-bpp x Set graphic mode with x bits per pixel
-size x y Screen (or window) is x*y pixels
Example:
demos/gears -size 320 200 -bpp 24
Updates
=======
You can find the latest LibGGI-driver and ggiglut on my
homepage:
