RAGE-engine foliage shader ?

[kilian277]

Hi,

Ever played gta4 or red dead redemption or max payne 3 from rockstar games ?

Well i do and i noticed on how the foliage is being rendered to the screen.

It’s start with green dots and transparent space between them is this a shader or is it rendering of the rage engine itself.

I have picture so you can see what i mean.

See what i mean ?

If so can someone tell me what technique is being used here.

Thanks !

The technique is called “alpha to coverage”.

You can see it in Street Fighter 4 about 3/4 of the way down this page; http://www.pcgameshardware.com/aid,685997/Street-Fighter-IV-PC-explained-in-detail/News/

Or you can download a demo of it in action by Hummus here; Humus - 3D
