Snow Hack 0

2008-06-25


No Snow

http://picogen.org/./gen-image/Weather FX/snow-1/no-snow.png

This is the scene without snow. (I personally like the aerial perspective in this non-snow image.)

Snow

http://picogen.org/./gen-image/Weather FX/snow-1/snow.png

If you look very closely, you will recognize that the whole lighting situation changed in this image (this is really a hack, since I made all particles emit light, thus the lighting is more unreleastic with snow).

For details on the underlying tec, see here.

This is actually the first "production"-render of picogen ever. Have a look at the caustics [0] in front of the spheres, *hmmm, tasty*.

I tried to implement the techiques from [0]. Unfortunenately, I failed this time, even if it looks promising. Better luck next time, I need clouds!

While not too spectacular, I still love the look of the clouds in above images, since at such daytimes clouds are usually not too far away from that look. Nevertheless, it looks crappy at noon.
