Well im making top view rally game and in track drawing function i use function like this:
glBegin (GL_QUADS);
for(x=0;x<32;x++)
{
for(z=0;z<32;z++)
{
u=trakmap[z32+x].u;
v=trakmap[z32+x].v;
glTexCoord2f(u,v+0.125);
glVertex3f (x,0,(z+1));
glTexCoord2f(u+0.125,v+0.125);
glVertex3f ((x+1),0,(z+1));
glTexCoord2f(u+0.125,v);
glVertex3f ((x+1),0,z);
glTexCoord2f(u,v);
glVertex3f (x,0,z);
}
}
But when it draws there are some fuzz between those quads.
