Normal Map Sprites

I found this very *awesome* post with interesting idea :

But as a complete n00b for this; i'm wondering if anybody could write/explain how to achieve this 'effect'.
(PS: for Mac please)

 

It's a shader that supports transparency and normals. Those are everywhere if you search for them. Then just add a light to the scene.

That blog post even has source code for the shader.

 

theres these tools,

This new tool is looking pretty cool so far...

I like the ability to paint the volumes on your own. The angle tool is nice.

And if you are coming from 3D land, this is a neat approach...

You could just have spoken chinese i wouldn't have understood anything as well

Can you please explain HOW do i use it ?

 

Looks cool yeah but not out yet ?

 

you can sign up for the beta at the bottom of the page.

 

So if i have a sprite that is animated i should be doing this for every frame/animation and sprite by sprite ?

 

You would do it for anything that you want to apply the affect to, yes.
