OpenGX: OpenGL for Wii and Gamecube

Hello guys! Here is my little contribution to the Wii/GC scene (and who knows, maybe Nintendo U???). This is an OpenGL-like wrapper which uses GX for the "real work". It's very basic but allowed me to compile and link my OGL-based game Toy Wars straight wihout any changes to the code. The only ...

Gamecube USART (serial port)

Hello! I wanted some information about GC's serial port (it has two, or at least there are 2 connectors under the case). I've seen there are some UART related routines at EXI subsystem. Does anyone has a clue on how to use them? Some examples for example? I want to be able to create peripherials for ...

Re: GX matrices

Yeah, I got it. The fact is that the matrices ara slightly different but I made them work. BTW I've managed to implement the basic things: texture loading (f*ck texture scrambling!), immediate mode, glDraw glPointer functions, matrix, blending, etc... At this moment I've managed to integrate it on ...

Re: GX matrices

Hi! I understand your example but that's not representative. I mean, the base of a 3D system is matrix-vector transformation. Based on this the matrices should be all equal and therefore obtain the same results. So there must be different matrix operations than just plain matrix multiplies right? I ...

GX matrices

Hello!

I'm writing an OpenGL like implementation for GX (more a wrapper than an implementation) and I'm facing problems with some matrices.
Why the matrices involved at gluPerspective differ from the GU one? The calc. is slighlhy different.

Thank you very much!
