Why not making the light sources move around?

Looks good so far.

it looks quite good but still you'll need to show us little more of FireFly power.

Make a bigger levels. Make both indoor and outdoor level. Then on some places for indoor levels use moving lights, like swinging ceiling lamp or some other moving object.
For outdoor level you can make sun moving and let us adjust it's speed.

Also some other customizable options should be implemented.
Anyway i hope you'll create something like that

He doesn´t have to do anything...


If you would read the readme, you would know that there are quite a few things to adjust on your own.

As far as I get it, this technique is for pointlights and not for far away directional lights like the sun. There will be heavy aliasing when using this technique for the sun. Aliasing should get more the further the shadowcaster is away from the light.

it wasn't an order, just a suggestion





ok i get it. but i haven't been able to download that demo cause it's 10 downloads limit had expired and due to that i didnt know

Hey,
for all of you who didn't grab the demo fast enough:
Thorsten (tkunze) has been kind enough to allow me to upload the demo to his website! He should post the link to the download when he gets a chance. Thank him for this

Also, as Slin said, the lights ARE customizable in real time. In fact, they are not movable on a path, but can be moved quickly by the user (hold down right mouse)! Please read the directions/readme! There is a reason why I wrote it.

Slin, you are right about the aliasing, however, it might be possible to adjust the texture storage to be able to store such large distances (and squared distances) such as using a rgba32bit texture and using 2 channels (64bits!) for each value. This should be similar to a 4 byte double variable.

oh yeah, If anyone is interested in working with me to improve the shaders, I can supply the source code. I am not interested in giving it out to everyone (yet) though. -Mike-

One channel for the distance should be enough, maybe two for the squared distance but I guess that also there a 32bit floating point channel is enough. I was refering to the limited texture resolution which is responsible for aliasing.

I was obviously to slow.

It's really a nice demo and it is much better than everything i achieved so far. Also the dirty look of the level looks great.
What i am interested in is to see how the approach works on outdoor levels because this is what i am working on.
And as expected you need some decent hardware to achieve good fps (my nVidia 7600 system dropped to 8 fps on 1280x1024, my 8800 GTS system achieved constantly 60 fps).

Keep on the good work.
