I have a ploblem with allegro. I want apply a texture (2.bmp 320x240
16bit ) at one polygon. I did in following method.
Why it is wrong ?
How can I resolve this problem ?

V3D_f v1,v2,v3,v4;
BITMAP *bmp,*texture;
PALETTE pal;
allegro_init();
bmp=create_bitmap(640,480);
texture=create_bitmap(320,240);
clear(bmp);
clear(texture);
set_color_depth(16);
set_gfx_mode(GFX_VESA1,640,480,0,0);
texture=load_bmp("2.bmp",pal);
v1.x=0;
v1.y=0;
v1.z=0;
v1.u=0;
v1.v=0;
v1.c=0;

v2.x=320;
v2.y=0;
v2.z=0;
v2.u=320;
v2.v=0;
v2.c=0;

v3.x=320;
v3.y=240;
v3.z=0;
v3.u=320;
v3.v=240;
v3.c=0;

v4.x=0;
v4.y=240;
v4.z=0;
v4.u=0;
v4.v=240;
v4.c=0;
quad3d_f(bmp,POLYTYPE_ATEX,texture,&v1,&v2,&v3,&v4);
blit(bmp,screen,0,0,0,0,640,480);
