I am looking at a stencil shadows implementation by mark kilgard, http://web.archive.org/web/20010722050058/reality.sgi.com/mjk/tips/rts/

And i am wondering (since im not on my pc right now) does it fade out shadows over the distance? If it doesnt, any ideas how i would do it?

Thanks.
Tim

don't fade out your shadows, fade out your lights.

But the shadows are based on the light positions, and thats all, arent they?

I will fade out the lights, but the positions will stay the same.

i'm no shadow casting expert by any stretch, but it seems to me that a shadow doesn't fade out so much as fade into the overall diminished amount of light.

picture a campfire at night. shadows are cast into the darkness where they are indiscernable from the general lack of light.

But i dont think Mark takes light strength into consideration (i might need to take another look at the code).

I think he only takes a position of a light.

take the light's strength (or even fallof if available) and your done... it's all about being creative with what you've got.
