No link works except for those in the first, original post. Just for your info.


Also i tried this out and liked it : but, this needs some improvement - maybe some blur between the samples if thats possible (guess not easily) and the bugs you know about anyways.

Also: why is the performance so weak? i get only 60 fps on my laptop :( doesn't seem usable for a game therefore, but looks really awesome, especially if you look towards the light source, with the object inbetween.

sorry, but i can't find source of this sample on my hard drive. Looks like i just deleted some of my old stuff. But i found some parts of this code in my another project. So, if you still need this, i will make new sample tomorrow (it's ~11.00 pm right now in Russia). Or if you need it right here and right now, just port original code http://sebastien.hillaire.free.fr/demos ... godray.htm

My mistake. :)

Can you remember what the archives was called?

I have several lightshaft archives on my disc..
One is from October 2007, and has Artheria in the material names..
Could you maybe give me some hints?

I can't even remember where I kept this stuff...
Hard drives are huge, and it's good. But some times it bringsome stupid problem.
 
Anyway, i will make new sample tomorrow.

Is this the old one, or you created new one updated?

Thanks

Looks like he created a new project, and used the old code with it.
Framelistener and materials/scripts/programs are from 2008. Project and app code is from today.

Wouldn't hold my breath. Considering that post is nearing on a decade ago.

i've uploaded it...IMHO really belongs in the sampleBrowser...
https://bitbucket.org/frostbyte2/ogreli ... downloads/

edit...i think something is wrong or changed with the [url] tag , or maybe i just don't use it right...
anyway the correct link is:
https://bitbucket.org/frostbyte2/ogreli ... downloads/

edit2...sorry, it seems that bitbucket is defaulting to private repos now, fixed it , repo is now public... :)

while I was at it, I took some inspiration from Crashy: viewtopic.php?t=33445
to make it work with ordinary spotlights, instead of requiring a special camera. Also it now leverages the shadow system for most of the things and integrates with texture shadows:

finally I send the shaders through Cg (I know a GLSL port would be better) so the demo works on both GL and D3D9 RenderSystems.
