DUM DUM DUM

I still need to work on the performance (horrific) and cleanliness of the code but first i'd rather tweak it to show off the effect first ( a couple of vars). Then I shall post the code!!!

Obviously for this you need

Deferred Shader and MRT G-Buffer
which can supply:

-depth
-normals
-shininess

then one more
-color after shading

Seems cool (if you can speed it up

), what shader spec is needed, 3.0 or more or is this only
working on like the latest cards (don't have a clue if my card can do colour after thingy in the G-Buffer :p) ?

i think this presents it better

shader spec same as SSAO...
G-Buffer is just a name for 3-5 RTTs rendered as MRT to do deferred shading

On Monday i will work on my ssao (only shades lines between objects, it sucks compare to BlindSide's).

Then Optimise...

Then by wednesday you will have the code
