model load problem

I've started my game engine (in OpenGL + SDL), but when I call render::draw after loading a 3ds file, all I get is a black screen. (Everything else is set up right, because I can do simple stuff like drawing primitives) Here's the code, Thanks a bunch for any help.

Code:

---

char render::Load3DS (mesh * Mesh, char *p_filename)
{
        int i;
        FILE *l_file;
        int temp;
        unsigned short l_chunk_id;
        unsigned int l_chunk_lenght;
        unsigned char l_char;
        unsigned short l_qty;
        unsigned short l_face_flags;
        if ((l_file=fopen (p_filename, "rb"))== NULL) return 0;
        while (ftell (l_file) < filelength (fileno (l_file)))
        {
                fread (&l_chunk_id, 2, 1, l_file);
                fread (&l_chunk_lenght, 4, 1, l_file);
                switch (l_chunk_id)
        {
                        case 0x4d4d:
                        break;   
                        case 0x3d3d:
                        break;
                        case 0x4000:
                                i=0;
                                do
                                {
                                        fread (&l_char, 1, 1, l_file);
//                  p_object->name[i]=l_char;
                                        i++;
                }while(l_char != '\0' && i<20);
                        break;
                        case 0x4100:
                        break;
                        case 0x4110:
                                fread (&l_qty, sizeof (unsigned short), 1, l_file);
                Mesh->NVertices = l_qty;
                                Mesh->pVerts = new float * [l_qty];
                                for (temp = 0; temp < l_qty; temp++) {Mesh->pVerts[temp] = new float[3];}
                for (i=0; i<l_qty; i++)
                {
                                        fread (&Mesh->pVerts[i][0], sizeof(float), 1, l_file);
                    fread (&Mesh->pVerts[i][1], sizeof(float), 1, l_file);
                                        fread (&Mesh->pVerts[i][2], sizeof(float), 1, l_file);
                                }
                                break;
                        case 0x4120:
                                fread (&l_qty, sizeof (unsigned short), 1, l_file);
                Mesh->NPolys = l_qty;
                                Mesh->pPolys = new unsigned short * [l_qty];
                                for (temp = 0; temp < l_qty; temp++) {Mesh->pPolys[temp] = new unsigned short[3];}
                for (i=0; i<l_qty; i++)
                {
                                        fread (&Mesh->pPolys[i][0], sizeof (unsigned short), 1, l_file);
                                        fread (&Mesh->pPolys[i][1], sizeof (unsigned short), 1, l_file);
                                        fread (&Mesh->pPolys[i][2], sizeof (unsigned short), 1, l_file);
                                        fread (&l_face_flags, sizeof (unsigned short), 1, l_file);
                                }
                break;
                        default:
                                fseek(l_file, l_chunk_lenght-6, SEEK_CUR);
        }
        }
        fclose (l_file);
        return (1);
}

Code:

---

void render::Draw()
{
        glClear(GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT);
        glLoadIdentity();
        glTranslatef(0.0,0.0,-300);
    glBegin(GL_TRIANGLES);
    for (int l_index=0;l_index<Engine.jug.NPolys;l_index++)
    {
                glColor3b(127, 0, 127);
        glVertex3f( Engine.jug.pVerts[ Engine.jug.pPolys[l_index][0] ][0],
                    Engine.jug.pVerts[ Engine.jug.pPolys[l_index][0] ][1],
                    Engine.jug.pVerts[ Engine.jug.pPolys[l_index][0] ][2]);
                glColor3b(127, 0, 127);
        glVertex3f( Engine.jug.pVerts[ Engine.jug.pPolys[l_index][1] ][0],
                    Engine.jug.pVerts[ Engine.jug.pPolys[l_index][1] ][1],
                    Engine.jug.pVerts[ Engine.jug.pPolys[l_index][1] ][2]);
                glColor3b(127, 0, 127);
        glVertex3f( Engine.jug.pVerts[ Engine.jug.pPolys[l_index][2] ][0],
                    Engine.jug.pVerts[ Engine.jug.pPolys[l_index][2] ][1],
                    Engine.jug.pVerts[ Engine.jug.pPolys[l_index][2] ][2]);
    }
    glEnd();
        SDL_GL_SwapBuffers();       
}

oh, and the mesh decleration

Code:

---

struct mesh
{
        float ** pVerts;
        unsigned short ** pPolys;
        unsigned short NVertices;
        unsigned short NPolys;
};

---

Try starting the rendering loop outside the glBegin and glEnd functions.

For example you have:

Code:

---

glBegin(GL_TRIANGLES);
for(stuff)
  do stuff;
glEnd();

---

change it to:

Code:

---

for(stuff)
  glBegin(GL_TRIANGLES);
  stuff;
  glEnd();

---

If that doesn't work, try running the debugger to see if the mesh data is being loaded properly.

[EDIT]
Actually, my first suggestion probably won't make a difference, but you can try it anyway :)[/EDIT]
