SUBJECT: SPS2 Newbie - ASE LoaderHi, after reading and understanding the first two tutorials (Path3/DMA tutorials) I decided to begin the adventure of coding sth.
Using some old classes I had for an old OGL Project I decided to load an ASE model and display it.
Everything ran fine till I decided to display the model on screen and I would like to know what's the problem since I am sure it's sth I am doing on wrong with DMA transfers. Here comes the code:
#undef DEBUG_DMA
#include <stdio.h>
#include <math.h>
#include <signal.h>
#include "dmavif1.h"
#include "screen.h"
#include <geommath/geommath.h>
#include "camera.h"
#include "p2lassert.h"
/*------------------------*/
#include "point.h"
#include "color.h"
#include "text.h"
/*------------------------*/
int loop_again=1;
point *vertexs;
int *cares;
int num_cares;
int num_vertexs;
// this is executed when ctrl-c is pressed, ideally it stops the loop.
// the deinit functions have to be at the end of the main after the loop.
void sig_handle(int sig)
{
loop_again=0;
}
// distribute sps2 specific global pointers to relevant classes
void DistribGlobPtrs(void * pDescCached, void * pDescUncached)
{
CDmaWrap::m_pDescCached = (sps2Memory_t *) pDescCached;
CDmaWrap::m_pDescUncached = (sps2Memory_t *) pDescUncached;
}
// labels for vu1 dummy-code
extern "C" void VU_vu1dummy_start(void);
extern "C" void VU_vu1dummy_end(void);
int iSPS2Device;
CScreen *cScreen=NULL;
void delete_screen()
{
if (cScreen!=NULL) delete cScreen;
cScreen=NULL;
}
void preload(){
text t;
t.create("./model_ase.ASE");
//Ara procedim a buscar el tamany de tot
t.seek("*MESH_NUMVERTEX");
num_vertexs=t.getint();
t.seek("*MESH_NUMFACES");
num_cares=t.getint();
vertexs=new point[num_vertexs];
cares=new int[num_cares*3];
t.reset();
int i;
i=0;
t.reset();
t.seek("*MESH_VERTEX_LIST");
for(i=0;i<num_vertexs;i++)
{
t.seek("*MESH_VERTEX");
t.getint();
vertexs[i].x=-(double)t.getfloat();
vertexs[i].z=(double)t.getfloat();
vertexs[i].y=(double)t.getfloat();
}
t.reset();
t.seek("*MESH_FACE_LIST");
i=0;
for(i=0;i<num_cares;i++)
{
t.seek("A:");
cares[i*3] = t.getint();
t.seek("B:");
cares[i*3+1]= t.getint();
t.seek("C:");
cares[i*3+2]=t.getint();
t.seek("*MESH_MTLID");
}
}

{
// Open sps2-library and setup PS2Linux stuff
iSPS2Device = sps2Init();

exit(-1);
}

DistribGlobPtrs(pDescCached, pDescUncached);
void * pAllDmaMem = pDescCached->pvStart;
int iVPU0; iVPU0=open("/dev/ps2vpu0", O_RDWR);
int iVPU1; iVPU1=open("/dev/ps2vpu1", O_RDWR);
