Why the tutorials are down?
Posted: Mon Nov 07, 2005 8:52 am
Hi all,
I'm new to PS2 programming , and I'm very instrested in this kind of HW (I've always been attracted by strange and non-standard HW like these consoles) .
I'd really like to learn how to program this beastie .
I've actually compiled the toolchain under my debian linux box and managed to make work the Hello World! programs proposed by the samples of PS2SDK.
Now I'm reading the cube and graph programs.
I've already programmed under OpenGL , so the cube program (even if it doesn't use openGL but another kind of 3d graphic library) is quite Comprehensible to me, but the graph program uses DMA and works with the inners HW registers of the machine and I have problems in understanding all about how it works.
I've tried to download the Tutorials , but the tutorial page doesn't work well, it gives me this error when I try to download one of the Dreamtime's tutorials :
There's another way to learn how the PS2 works with GIF and GS registers and DMA?
I think that the GIF_SET_RGBAQ and GIF_SET_XYZ are used to set , respectively, the color of the drawing and the position of the vertices.
The problem is that I don't get what's the use of GIF_SET_TAG and GIF_SET_PRIM .
What's their purpose ?
How does the PS2 understand what is the right geometrical figure to display?
Thanks for your help.
