On the off chance you're being serious, you can't get the Triforce in Ocarina of Time.
This image...

... of Adult Link finding it on a pedastal somewhere is from an early version of the game, and didn't make it into the final release version. Young Link didn't even exist yet when this screenshot was released.
The only time the Triforce is seen in Ocarina is during the cutscene explaining that the three goddesses left it behind when they departed (the only full version in the game), and in three ghostly 2D images on the backs of the right hands of Link, Zelda, and Ganondorf (each with a different portion illuminated), and even those just appear during scripted events.
