I'm trying to draw 3d-shapes with Allegro, but I haven't had any progress
yet.
The examples no. 22 and 26 are pretty complex and I don't understand them.
Please could anyone give me lines, that would draw a triangle with the
triangle3d
function ?

I tried things like this:
int main()
{
BITMAP *bmp;
V3D vtx1={10,10,250,0,0,0xD0};
V3D vtx2={100,10,250,0,0,0xD0};
V3D vtx3={10,100,250,0,0,0xD0};
allegro_init();
set_gfx_mode(GFX_AUTODETECT,800,600,800,600);
set_projection_viewport(0, 0, SCREEN_W, SCREEN_H);
triangle3d(screen,POLYTYPE_FLAT,NULL,&vtx1,&vtx2,&vtx3);
getch();
getch();
return 1;
}

but I couldn't notice any output on the screen.
What should I do ?
