I need Photoshop help

[alarid0]

I've never bothered looking into this much...this entire time I've just accepted that I dont know how to fix it.

When transforming something in photoshop, it automatically smooths it out, blurring the inside and around the outside edge has a fade to transparent.

How do I remove that? I know how to change it when adjusting the entire document size (resample image: nearest neighbor) but that doesn't help. I need to transform an item into many different angles and perspectives, but cant have that anti aliased edge
