Is this a viable technology?

Hi everyone!

I didn’t want to make a post that’s screaming “OH MY GOD WE NEED THIS!”, but rather ask the question if this technology is as good as it seems and I’d like to hear a few pros and cons from people that know more about this stuff than I do.

So first of all, here’s the video I’m talking about:

After googling the title I also found their research paper:
Real-Time Polygonal-Light Shading with Linearly Transformed Cosines

I mean if everything they claim is true, then this would be incredible stuff to have, right? So is it actually as good as it seems or is there a good reason to not implement something like that?

EDIT:
I also recomment downloading their demo. It’s fun to play around with it for yourself. Seems like the actual reflection on the ground doesn’t get blocked by objects. So there’s the first con.

Isn’t it the same technique that was used in ADAM Unity GDC demo?

Based on the video it sounds like it needs a “High End GPU” so, probably not viable for mainstream “yet”
