Is it possible to add one texture to another texture, at specific coordinates? Like if I want to add a small texture(16x16) to big texture (1368 x 768) with coordinates ( 100, 100) so the small texture goes to specific coordinates (100, 100 ).

  • \$\begingroup\$ So I wanted put other texture to texture ( blend them together) with exact coordinates inside the other texture. Like I wanna put 16x16 texture to 100,100 etc. You got it now ? \$\endgroup\$ – Alker Feb 3 '14 at 12:13

Yes, glTexSubImage may be what you are looking for.
