Repeating only a portion of a texture in OpenGL ES?

I know it's possible to repeat an entire texture by setting the wrap mode to GL_REPEAT, but is it somehow possible to开发者_StackOverflow中文版 repeat only a subregion of the texture? For example, when the texture is part of an atlas.

I'm targetting OpenGL ES 1.x, so shaders are out.

Unfortunatelly, it is not possible. The only thing you can do it to repeat side pixels (if the image is at the edge of a texture altals).

If you need tiling – probably the only solution here is generate is with geometry. Otherwise, just go with a separate texture.
