But I wonder how many who need to fake the fake?
After trying a SSAO shader and seeing some unsatisfying performance(on a very primitive example) , I decided to look into alternative solutions that would be faster to render and could work on older machines.
So I did a simple test where i darkened vertexes next to other blocks, and it looks something like this:
It looks really bad in a few spots, and quite good in others, but on average it is not as good as I was hoping for, so my next attempt will be to use gradient shaded textures instead.
Currently things are only evenly gradient, but I want the shadows to be stronger the closer you get to a corner, This is not possible to do when we color the vertices's directly, but would be very simple to do on a texture.
This is of course a very fake way to do "Ambient Occlusion", but considering that we get it almost for free, I can live with it.
Note: The picture to the right has slightly darker shadows.
Could you post a picture on the laggy-version also?
SvaraRaderaHi Anonymous ;)
SvaraRaderaI probably didn't express my self very clear, but the -very primitive example- was not running on my engine, it was an SSAO xna example.
You can find the sample here:

But it looks like it is highly un-optimized, it was acting very slugerish on my computer, and I don't feel it is worth sacrifice all that power when i can create more simple alternatives that would run on much slower computers.
I was also unable to render the ssao shader as 'final'(ssao+textures) on my computer, it might have been a compatibility problem with my graphics card.
Oh i see, my bad. Anyways the new one you implemented looks great :) Keep it up!

SvaraRaderaI beleve that the graphIcs looks great. Gives me that old liero pixilated feel!
