MIguel P Posted May 9, 2007 Share Posted May 9, 2007 Hello everyone. I've done a little scene to try making volumetric snow with sprites. I am surprised with the results because the render times are not too long. I think I'm going to try something like Digital Domain's avalanche in XXX The scene is inspired in the helicopter crash sequence from Day after tomorrow. I know the snow motion isn't realistic. There is only a single layer of snow, and there aren't snow chunks. http://www.miguelperezsenent.com/Media/Tes...w_landing_2.avi Quote Link to comment Share on other sites More sharing options...
michael Posted May 9, 2007 Share Posted May 9, 2007 sprites you say? really great look... always impressive Miguel... Quote Link to comment Share on other sites More sharing options...
aracid Posted May 9, 2007 Share Posted May 9, 2007 thats looking really cool, for a base element, its really promising and really doesnt look like a sprite solution. Quote Link to comment Share on other sites More sharing options...
MIguel P Posted May 9, 2007 Author Share Posted May 9, 2007 Thank you Yes, sprites. The render of the image I attached above took 34 seconds including deep shadow calculation with 38609 sprites. Quote Link to comment Share on other sites More sharing options...
agentex Posted May 9, 2007 Share Posted May 9, 2007 Miguel, you rule! Really like what you're doing and how you are pushing things. One thing that would be cool in this one would be to see the displaced snow as the pod burries itself into the powder. The other thing is, you do alot of great work with sprites, you thought about doing more with volumetrics at some point?

Val Posted May 10, 2007 Share Posted May 10, 2007 very nice (tecnique) good to know I can get that look with sprites Quote Link to comment Share on other sites More sharing options...
Marc Posted May 10, 2007 Share Posted May 10, 2007 sprites + dshads can get a surprising amount of depth and volume. I often find myself choosing sprites to do something instead of a true voxel approach. Very cool stuff though, Miguel. Well done. M Quote Link to comment Share on other sites More sharing options...
Andz Posted May 10, 2007 Share Posted May 10, 2007 Yep, that is looking really cool. Congratulations! Quote Link to comment Share on other sites More sharing options...
stevenong Posted May 10, 2007 Share Posted May 10, 2007 Hey Miguel, That looks really good. I find the fingers stop pretty abruptly. Maybe a bit more variance in the weight so that some fingers drop faster? Also, the shadow seems a bit dense but overall, it's a great start! Cheers! steven Quote Link to comment Share on other sites More sharing options...
MIguel P Posted May 10, 2007 Author Share Posted May 10, 2007 Thank you for the comments Yes, I know the motion isn't very realistic, But it's just a test, I'm not going to work on this scene too much. Here is a quick test about doing an avalanche: http://www.miguelperezsenent.com/Media/Tests/avalanche.avi Quote Link to comment Share on other sites More sharing options...
michael Posted May 10, 2007 Share Posted May 10, 2007 very nice! IIRC...there was an article about this shot... something about a curve that is built to follow the terrain from which the particles are gererated... I think something like this would help...

ddingddong Posted May 11, 2007 Share Posted May 11, 2007 Hi Miguel If you okay, could you show me simple sprite + dshad example file? I really like your shot. Quote Link to comment Share on other sites More sharing options...
MIguel P Posted May 11, 2007 Author Share Posted May 11, 2007 Hi Miguel If you okay, could you show me simple sprite + dshad example file? I really like your shot. The best thing you can do is read my meteor tutorial at my web site http://www.miguelperezsenent.com/ The shader I've used for the snow is exactly the same that I explain in my tut. I've only changed the frequency and roughness parameters 1 Quote Link to comment Share on other sites More sharing options...

MIguel P Posted May 12, 2007 Author Share Posted May 12, 2007 I've already read it. My main concern is combine with dshad. Is it ok question about it later then that ? Thanks~ In my tutorial I explain how to set the deep shadows Quote Link to comment Share on other sites More sharing options...
