   About lighting bolts and rain drops
  Some time ago I've decided to make some nature effects in 3D,now work is in progress."Image gallery" part seems me more suitable for complete projects,and my question not concern to programming /3D /games directly , i.e such parts as "graphics programming and theory" etc. I just wonder your impressions and especially notes,so may I show & discuss it here?[Edited by - Krokhin on June 7, 2009 6:35:53 AM]
Quote:Original post by Krokhin"Image gallery" part seems me more suitable for complete projectsDoesn't have to be, I've seen a lot of tech demos or even just renders there.But I have to say the IOTD is definitively improving lately with featuring more and more actual completed games. But I enjoy just looking at pretty pictures (or should I say 'GPU porn') too.   ;  Well,I see that nobody want to write something about it.It's a pity.No feedback-no articles.PS Everything ok,I've solved this problem at photo-forum.The question was "does such lightings exist or not"I found out there that it's mostly a long-exposure frames,i.e  actually a bunch of lightings from one point but in different time,and no need to draw it at once. Thank you for attention [smile][Edited by - Krokhin on June 7, 2009 11:25:09 PM];  And another one ">video, lightings were corrected slightly.[Edited by - Krokhin on June 14, 2009 10:19:48 AM];  So let me get this straight. That's not a real picture of lightning over Albuquerque but a computer generated picture, or that's a real picture of Albuquerque with computer generated lightning overlayed?   ;  I'd just like to say that video looks completely gorgeous. I'm not much into the topic, but that's one of the nicest lightning bolt renderings I've seen in computer graphics. Are they procedural? The only small detail that I didn't recognize from real recordings was the relatively large blue light spots appearing under the bolts. It looks nice anyway.What are those ellipses in the air for? They remind me of UFO's with cloaking effect :)   ;Quote:Original post by LessBreadSo let me get this straight.

They remind me of UFO's with cloaking effect :)Thanks,but not completly(and never will be:) Bolts are partially procedural,lightspots is an additional lighting-may be it's not so realistic stil.An ellipses are just a clock,every UFO shows a time -12 small balls around the border shows hours as usual,other 3 balls -h:m:s.Instead of  "Alien time" may be another names "Alien's time" or "The time of aliens",i'ts not important,I think.I still try lighting dwawing,">here slightly another kind,but I'm afraid that video compression kills small details.I must say about music in video too,this is my favourite-Carolyn Southworth "Anchor in the storm"[Edited by - Krokhin on June 14, 2009 12:49:47 PM];Quote:Original post by KrokhinWhat is Albuquerque ? :) It's the largest city in New Mexico. Here is a picture of it's skyline.

I  feel that I need a special opinion poll among guys from Florida [smile]
