Changes in version 3.0
----------------------
- Just some changes to bring the library up to date with Mesa 3.0
Version 3.0 is compatible with v2 of AmigaMesaRTL
Introduction
------------
This port of the OpenGL-like Mesa 3.0 is specifically aimed at mid-range
Amiga computers, i.e. at least an '030, FPU, and a fair amount of RAM (at
least 8MB).
Rendering is not done directly to a window or screen. Instead, an internal
buffer is maintained by the driver to which all the drawing is done. When
all the drawing is done (i.e. glFlush() is called), an output handler is
called. An output handler can do all sorts of things. For example, the
supplied dl1 output handler uses the dl1 colour quantization code to
quantize the buffer to a displayable number of colours and C2P it to an
AGA window. Other output handlers may write the buffer to an ILBM file,
dump it to a truecolour display, send it to an image editing program, or
transmit it over a network, or whatever.
Features
--------
- Complete Mesa implementation
- Faster and much better output than CyberGL
- A run-time library: no more 200k+ programs like with StormMesa
- A GLUT lookalike runtime library featuring most of the important GLUT
functionality
- Output handlers to support an infinite variety of ways to process the
output
- A separate driver library. Write your own driver if you want.
Compiling
---------
To compile the library, you will need to original Mesa 3.0 distribution
(available at e.g. ftp://iris.ssec.wisc.edu/pub/Mesa/ ), and the SAS/C
compiler (I used version 6.58).
Finally
-------
Many of the features in this version are due to the excellent feedback
from Szymon Ulatowski (of Framsticks fame http://www.frams.poznan.pl/).
He is also doing some interesting things with AmigaMesaRTL and MUI, which
should appear at http://friko.onet.pl/rz/szulat/mesamcc/
Thanks Szymon!
