11 | This is a simple test demo for the MESA (5.0) |
||
12 | libraries, the low level graphic drivers is |
||
13 | the SVGA (from the SVGAlib) |
||
14 | |||
15 | The cards actually supported are: |
||
16 | |||
17 | GEFORCE TNT TNT2 - driver name NV3 |
||
18 | RAGE128 RADEON - driver name R128 |
||
19 | SAVAGE VIRGE - driver neme SAVAGE |
||
20 | |||
1139 | giacomo | 21 | You need a test.png file present in the |
22 | same directory of the demo. Remember that |
||
23 | the file system support only a DOS FAT16 fs. |
||
24 | |||
25 | The PNGlib will load this file and it |
||
26 | will be used as a texture. |
||
27 | |||

30 | The demo is composed by: |
||
31 | |||
32 | MAKEFILE The makefile used to compile the application |
||
33 | README.TXT This file |
||
1139 | giacomo | 34 | INITFILE.C The init file (with fs initialization) |
35 | MESAREF.C The MESA Demo |
||
36 | TEST.PNG The PNG texture image |

40 | - To specify your card change the line |
||
41 | |||
42 | #define CARD <driver name> |
||
43 | |||
44 | - The demo calls the grx and off-screen Mesa functions. |
||
45 | The resolution must be 16 bitsperpixel (64K colors) and |
||
46 | the graphic access mode must be linear. |
||
47 | |||
48 | - There are two buffers |
||
49 | |||
50 | The video buffer (video_buf) |
||
51 | The virtual buffer (rgb_565_buf) |
||
52 | |||
53 | copy_videomem_16to16 links these buffers |
||
54 | |||
1139 | giacomo | 55 | - If the texture load fails, sys_end() is called |
