Does anyone have a more indepth explanation of some of the samples in the SDk. Like in the gu blit sample half of the things i don't quite understand what they are doing, and i dont really need the fps part and im not sure what parts the fps are using and what parts the bliting are using.
Example:
| Code: | // setup
sceGuStart(GU_DIRECT,list);
sceGuDrawBuffer(GU_PSM_4444,(void*)0,512);
sceGuDispBuffer(480,272,(void*)0x88000,512);
sceGuDepthBuffer((void*)0x110000,512);
sceGuOffset(2048 - (480/2),2048 - (272/2));
sceGuViewport(2048,2048,480,272);
sceGuDepthRange(0xc350,0x2710);
sceGuScissor(0,0,480,272);
sceGuEnable(GU_SCISSOR_TEST);
sceGuFrontFace(GU_CW);
sceGuEnable(GU_TEXTURE_2D);
sceGuClear(GU_COLOR_BUFFER_BIT|GU_DEPTH_BUFFER_BIT);
sceGuFinish();
sceGuSync(0,0);
sceDisplayWaitVblankStart();
sceGuDisplay(1); |
All it has is //setup. Really I dont quite understand how much of that is really needed to blit images to the screen, if someone could go through the whole gu blit sample and make a more detailed explanation of it i would appreciate it very much. Thanks in advanced - Vale
[EDIT] if there is already a more in-depth version please tell me where to get it i searched and couldn't find one. |
