Creating display list after sceGumPerspective ??

[Drakon]

Hi

I'm researching how to get better performance in my new game and I have problems with display list.... -_-'

Big question is - Do I need to create display list before setting sceGumPerspective or sceGumOrtho ?

Here I'm explaining - I'm initializing GU, next creating display list for small cube and setting perspective - everything is working ok. But if I initialize GU then setting perspective and create display list for cube - nothing on the screen :/

I know this might be dumb question but did any one encountered this?

Working code looks like this:

Code: Select all

dList = malloc( 262144 ); 

		// Init GU
		sceGuInit();
		gumInit();
		sceGuStart( GU_DIRECT, dList ); 
		fbp0 = 0;
		sceGuDrawBuffer( GU_PSM_8888, (void *)fbp0, BUF_WIDTH );
		fbp0 += FRAME_BUFFER_SIZE;
		sceGuDispBuffer( SCR_WIDTH, SCR_HEIGHT, (void *)fbp1, BUF_WIDTH);
		fbp0 += FRAME_BUFFER_SIZE;
		valloc(FRAME_BUFFER_SIZE);
		sceGuDepthBuffer((void *)fbp0, FRAME_BUFFER_WIDTH);
		fbp0 += (FRAME_BUFFER_WIDTH*SCR_HEIGHT*2);				// 16bit depth buffer
		valloc(FRAME_BUFFER_WIDTH*SCR_HEIGHT*2);


		sceGuOffset( 2048 - (SCR_WIDTH/2), 2048 - (SCR_HEIGHT/2));
		sceGuViewport( 2048, 2048, SCR_WIDTH, SCR_HEIGHT);
		sceGuDepthRange( 65535, 0);

		// Set Render States
		sceGuScissor( 0, 0, SCR_WIDTH, SCR_HEIGHT);
		sceGuEnable( GU_SCISSOR_TEST );
		sceGuDepthFunc( GU_GEQUAL );
		sceGuEnable( GU_DEPTH_TEST );
		sceGuShadeModel( GU_SMOOTH );
		sceGuFrontFace( GU_CW );

		//culling
		sceGuEnable(GU_CULL_FACE);
		sceGuEnable(GU_CLIP_PLANES);
		
		sceGuEnable(GU_LIGHTING);
		sceGuEnable(GU_LIGHT0);
		
		sceGuAlphaFunc(GU_GREATER,0,0xff);
		sceGuBlendFunc(GU_ADD, GU_SRC_ALPHA, GU_ONE_MINUS_SRC_ALPHA, 0, 0);

		sceGuTexMode(GU_PSM_8888,0,0,0);
		sceGuTexFunc(GU_TFX_REPLACE,GU_TCC_RGBA);
		sceGuTexFilter(GU_NEAREST,GU_NEAREST);
		sceGuTexWrap(GU_REPEAT,GU_REPEAT);

		sceGuTexScale(1,1);
		sceGuTexOffset(0,0);

		sceGuFinish();
		sceGuSync(0,0);

		sceDisplayWaitVblankStart();
		sceGuDisplay(GU_TRUE);

		//for analog pad
		sceCtrlSetSamplingCycle(0);
		sceCtrlSetSamplingMode(PSP_CTRL_MODE_ANALOG);
		// finish

//init cube list
		sceGuStart(GU_CALL, boxList);
		sceGumDrawArray( GU_TRIANGLES, GU_NORMAL_32BITF|GU_VERTEX_32BITF|GU_TRANSFORM_3D,12*3,0,boxVerts);
		sceGuFinish();


//set perspective
sceGumMatrixMode(GU_PROJECTION);
		sceGumLoadIdentity();

		sceGumPerspective( 75.0f, 16.0f/9.0f, 1.0f, 100.0f);
		
		sceGumMatrixMode(GU_VIEW);
		sceGumLoadIdentity();

		sceGuClearColor( GU_COLOR( 1.0f, 1.0f, 1.0f, 1.0f ) ); 
		sceGuClearDepth(0);	

		sceGumMatrixMode(GU_MODEL);
		sceGumLoadIdentity();

Any ideas ?

Partially Solved
I had only to remove :

Code: Select all

sceGumMatrixMode(GU_MODEL);
		sceGumLoadIdentity();

from perspective settings end put at the beginning of the rendering function....

Haha but now another bug appeared - I cant use sceGumLookAt(&cameraPos, &lookAtPos, &upVec); -_-' it's simple stop working....
