Texture Tiling

Tiling is controlled by the WRAP texture parameter:

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S,
                   GL_REPEAT)
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T,
                   GL_REPEAT)

for no tiling:

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S,
                   GL_CLAMP)
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T,
                   GL_CLAMP)
