brainmuffin Posted March 4, 2010 Posted March 4, 2010 Why not use sprites, with high transparency, and use a bar shaped invisible emitter that moves toward the camera? Quote
Eric2575 Posted March 4, 2010 Author Posted March 4, 2010 After posting this last night, I did some experiments with the smoke project. I got some nice animated rolling fog effects, but the render time per frame for just the fog was three minutes. I shudder to think what it would be with the ocean rig and the Nautilus in the scene. I know, I know, everyone is now saying what about rendering it separately and compositing it? Hmmm, maybe a combination of animated rotoscope and sprite effects... Chris, could you post an animated example of your volumetric fog for us please? Go ahead and post it here since it's relevant to this thread. Holmes, do you have a short clip of your technique with the fractal sum? I'll try and knock out an example of the rotoscope fog and post it. Quote
Eric2575 Posted March 4, 2010 Author Posted March 4, 2010 Quick question: We have all played with swirling white smoke in the fire tutorial, but can we produce grayish fog like this? - http://activeden.net/item/fog-video-effect/949 I tried changing the sprite, but haven't gotten it yet. Edit: Spoke too soon, just didn't save the tga with the alpha channel. Ok, now I have a grayish fog, but still want to explore the most efficient way to do this for the animation, so keep the input coming please. Quote
HomeSlice Posted March 5, 2010 Posted March 5, 2010 Here are some very simple short tests. You can get as complex with the fractal sum material as you want, add a gradient etc ... One is the rendered fog animation as a fog image and the other is rendered as a camera rotoscope. I've also added the project file. camera_roto.mov fog_image.mov fog_test.zip Quote
Eric2575 Posted March 5, 2010 Author Posted March 5, 2010 I feel like I'm in the witch's cauldron brewing up some secret potion. That's a great start and points me in the right direction. Thanks Holmes Quote
Eric2575 Posted March 7, 2010 Author Posted March 7, 2010 In the mean time...I couldn't resist another still. This was one pass and took about four minutes at 1920x900. Added the waterline shadow and did a slight sharpen in PS. I reduced the render time for the animation quite a bit by taking out all the lights except one for the green water illumination. The first still I did used 8 green ambiance lights, this one uses one for pretty much the same effect. Quote
TheSpleen Posted March 7, 2010 Posted March 7, 2010 I shall repeat a post I made earlier in this thread: Wow Quote
TheSpleen Posted March 7, 2010 Posted March 7, 2010 Your attention to detail is astounding. only crit I would have is I would love to see the captain at the helm. Quote
PurpleDingo Posted March 10, 2010 Posted March 10, 2010 Sorry, I don't really have anything constructive, but "wow". Awesome, awesome, awesome! 20,000 Leagues has always been one of my favorite live-actio Disney flicks, right up there with Tron. Quote
Darkwing Posted March 10, 2010 Posted March 10, 2010 I never saw the film, only read the book, but man, that is like exactly how I see the ship when I read it. Utterly astounding, terrific work, wouldn't expect anything less of you Quote
Hash Fellow robcat2075 Posted March 15, 2010 Hash Fellow Posted March 15, 2010 Wonderful looking shot, Eric! How could we get that to work in animation? I never saw the film Probably the best live-action film Disney ever did. You oughta rent it. Quote
Darkwing Posted March 15, 2010 Posted March 15, 2010 I wonder if we still have any rental stores. I'd probably be better to find it on iTunes or something Quote
Paul Forwood Posted March 15, 2010 Posted March 15, 2010 Another amazing model, Eric! Here is the 1954 trailer that is on YouTube: Quote
Darkwing Posted March 15, 2010 Posted March 15, 2010 wow, just looked up the cast list, it has quite a half decent cast listing, kirk douglas, peter lorre, some pretty good actors! I really will have to find a copy. Quote
Eric2575 Posted March 17, 2010 Author Posted March 17, 2010 Thanks for the comments everyone. I posted the last image on CGTalk and could use your guys support Quote
