I want to have an instructions page in my OpenGL ES game. One approach is to combine 2d and 3d rendering and use eglSwapBuffers.

I read about this on this forum and it seems messy, so maybe it is better to write all the instructions on a texture, which I then put on a rectangle which is shown directly in front of the camera? This approach would avoid any mixed rendering.

If it is better to combine 2d and 3d rendering and use eglSwapBuffers, has anyone an example on how to implement this?
