HELP PSPGL

[henamaral]

I m trying to use this code below, But doesn't work. I don't what is wrong in the code.
Please Help me.

#include <GL/glut.h>
#include <GL/gl.h>
#include <pspkernel.h>
#include <pspdebug.h>
#include <pspctrl.h>
#include <stdlib.h>
#include <stdio.h>
#include <string.h>

PSP_MODULE_INFO("OPEN",0,1,1);
#define printf pspDebugScreenPrintf;

int exit_callback(int arg1,int arg2,void *common){
sceKernelExitGame();
return 0;
}
int CallbackThread(SceSize args, void *argp){
int cbid;
cbid = sceKernelCreateCallback("Exit Callback",exit_callback,NULL);
sceKernelRegisterExitCallback(cbid);
sceKernelSleepThreadCB();

return 0;

}
int SetupCallbacks(void){
int thid = 0;
thid = sceKernelCreateThread("update_thread",CallbackThread,0x11, 0xFA0, 0, 0);
if(thid >=0){
sceKernelStartThread(thid,0,0);
}
return thid;
}



static void display(void) {

glClear (GL_COLOR_BUFFER_BIT);

glColor3f (1.0, 1.0, 1.0);

glBegin(GL_POLYGON);
glVertex3f (0.25, 0.25, 0.0);
glVertex3f (0.75, 0.25, 0.0);
glVertex3f (0.75, 0.75, 0.0);
glVertex3f (0.25, 0.75, 0.0);
glEnd();
glFlush ();
}

void init (void)
{

glClearColor (0.0, 0.0, 0.0, 0.0);
glMatrixMode(GL_PROJECTION);

glLoadIdentity();
glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0);
}
int main(int argc, char* argv[]){

pspDebugScreenInit();
SetupCallbacks();
sceCtrlSetSamplingCycle(0);

glutInit(&argc,argv);
//glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB);
glutCreateWindow( __FILE__);
init ();
glutDisplayFunc(display);
glutMainLoop();

sceKernelSleepThread();

return 0;
}

Thanks

try putting your code in the [ code ]box.

anyway the reason it doesnt work is because. You have to through the function within the pspgl functions GLCHK(GL_CALL);

example:

Code: Select all

        GLCHK(glViewport(0, 0, w, h));
        GLCHK(glMatrixMode(GL_PROJECTION));
        GLCHK(glLoadIdentity());
        GLCHK(glOrtho(-2, 2, -2, 2, -2, 2));
        GLCHK(glMatrixMode(GL_MODELVIEW));
        GLCHK(glLoadIdentity());

check out the pspgl glut example. it should be all there.

right now single-buffer displays are not supported, the flag is ignored. Call glutSwapBuffers().

btw: does anybody needs single-buffer displays? is there any need to implement it?

[henamaral]

Thanks Thanhda, I will go try to do this.

What is wrong now?
Please

[Thanhda]

please use the code function to post your code. have you tried compiling the sample code. it should be located in pspdev/psp/sdk/trunk/pspgl/glut-test/ try compiling that. see if it works. if not then you did not install it correctly. use svn to get the lastest version of the pspsdk.
