Worker 11811 Posted March 16, 2006 Share Posted March 16, 2006 Pictures below contain female nudity. Rated "R" material. Original Picutre. Using GIMP's "Impressionist" Filter to render a fur-like texture. Furred Picutre. My own self-critique: 1) Less random variation in fur texture. Needs to "flow". 2) Needs less transparency. The stripes showing through make the fur look "busy". 3) Needs to look more 3-dimensinal. Should probably render in two or three layers. Should I manually blur the boundaries between skin and fur?

Fox Posted March 16, 2006 Share Posted March 16, 2006 To be blunt, it just looks like a blurry version of the shirt she has on. Link to comment Share on other sites More sharing options...
Worker 11811 Posted March 16, 2006 Author Share Posted March 16, 2006 I don't mind blunt. Blunt is often preferable. Longer strands & more flow? Should I just quit fussing around and go with a full-blown particle system? It might take more computes than I have. I was trying to find a short cut.

Guest Posted March 16, 2006 Share Posted March 16, 2006 If your going to render a pc in fur at least make the fur a good looking full length Fox or Mink................. Link to comment Share on other sites More sharing options...
Worker 11811 Posted March 16, 2006 Author Share Posted March 16, 2006 It was a trial run of an idea I had. Sometimes, if you look at your own work you don't see it for what it really is. You tend to put it up on a pedestal, so to speak. Putting it out there for others to criticize helps shine some light on it and bring you back to reality. I really do appreciate criticism even if it is negative. When I think about it, negative criticism is probably more helpful. I'm going back to the drawing board on this. What I've done is to use a filter that paints a pattern over and over to simulate fur. It works OK but it has limitations. Maybe I can tweak it. I think I'm going to try to set up a particle system that will render each strand of fur, individually. It's going to take a huge amount of computer horsepower. I think I can do the run-of-the-mill editing on my computer at home then use the computers at work to do the final render. I'll have to wait till after hours to do it though. Thanks! Your thoughts are appreciated. Link to comment Share on other sites More sharing options...
furfreak Posted March 17, 2006 Share Posted March 17, 2006 Rendered fur is hard to do. I've seen some examples on the net and most of them have been small pieces. If you can pull it off it would be quit a feat. Link to comment Share on other sites More sharing options...
Worker 11811 Posted March 18, 2006 Author Share Posted March 18, 2006 While I don't intend to create a fur beast like "Sully" from the Pixar movie I think I can, at least, come up with something. I've seen it done. I'd like to take a crack at it. As it is, today, "Sully" is the Holy Grail of rendered fur! Link to comment Share on other sites More sharing options...
s1m17 Posted March 18, 2006 Share Posted March 18, 2006 King Kong was pretty good too. Link to comment Share on other sites More sharing options...
Worker 11811 Posted March 18, 2006 Author Share Posted March 18, 2006 Yeah, but Sully was fluffier. Here's a test render. FurBall.jpg I just rendered particles onto the surface of a sphere to simulate fur. Once I learn the parameters I should be able to change the color, length and texture of the fur. I think I can even put random variation into the hair length to simulate underfur. Now, to pracice up and render that fur onto a complex object! Then, to Photoshop that object onto a picture.

Worker 11811 Posted March 19, 2006 Author Share Posted March 19, 2006 Glad you guys think I'm on the right track with this one! What I have to do is design a 3-D framework that mimicks the clothes the model is wearing. Then I have to tell the comptuer to put fur on that framework. Finally I Photoshop the two pictures together. The furry ball was a 32 X 32 (segments X rings) sphere with 50,000 particle vectors attached to it. It took a little more than a minute to render just that little "tribble". The time it takes to render goes up exponentially as you add particles. I can only get up to about 100,000 particles before my computer comes to a grinding halt. The 3-D framework that I have to design to cover that model in fur will probably have 500,000 particles. My computer will be screaming for mercy by the time I'm done! I'm probably going to have to divide it up into sections and render each seperately then Photoshop them all together. This gives me a whole new appreciation for what Pixar did with Sully! They say it took the better part of a day just to render ONE FRAME of him! I'll try to keep you up to date... If I don't get frustrated and give up. If anybody wants to play with that tribble, go ahead and use it. Link to comment Share on other sites More sharing options...
Worker 11811 Posted March 23, 2006 Author Share Posted March 23, 2006 Been working on my fur renderings. Here's another fur ball I did as a test. Test Fur 1 Getting better? What would make it better? More hairs? Thicker/Thinner hairs? Longer/Shorter? More/less variation in length? More/less gravity to make the hairs droop? Oh! In my trials, I found out that it's not as hard to make Sully Fur as I thought! (Okay, I used a library of presets that another guy made.) Link to comment Share on other sites More sharing options...
Mr Barguzin Posted March 23, 2006 Share Posted March 23, 2006 Okay... quick inspection..... looks like dog hair *grin*... long haired dog of course. Fur should be thinner, in truth, as fine as you can possibly go and at that point length should be equal, not unlike top quality pelts. Link to comment Share on other sites More sharing options...

Worker 11811 Posted March 23, 2006 Author Share Posted March 23, 2006 Okay... Thinner strands. Shorter. More density. Less random variation. Right now, I have the variation in hair length set at a random +/- 10%. Do you want 0% randomness or maybe just 1%. I'll crank the density from about 30,000 hairs up to maybe 50,000. I can go as high as 100,000 but time to render increases exponentially. (If I double the number of hairs, it takes 10 X longer to render, for example.) It can bring the computer to a grinding halt if I go too high. Length is set at 75 units right now. I'll lower it to, what? 50? 25? I can make the strands taper or not. You want a sheared look? I'll make them not tapered. How's the color? Do you want a more even coloration? Or, is the mottling good? The color can be almost anyting. Even Tiger or Zebra stripes! I'll work on it. It'll take some time. The computer I need to render on is in use during the day. I have to do it on off-times. Link to comment Share on other sites More sharing options...
Fox Posted March 25, 2006 Share Posted March 25, 2006 I'll agree with Mr. B on this. Shorter, finer, denser. And I think the variation in color is more convincing than making it a uniform color. Sorry I can't give numbers, but I'm not as technical as I'd like to be. Link to comment Share on other sites More sharing options...
Worker 11811 Posted March 25, 2006 Author Share Posted March 25, 2006 Here's another fur ball. Length = 25. (Down from 50) Density up to 50,000. Less taper. Less gravity. Link to comment Share on other sites More sharing options...
Guest Posted March 25, 2006 Share Posted March 25, 2006 A lot nicer than the ones my cat use to give me. much nicer. Like natural beaver. OFF Link to comment Share on other sites More sharing options...
Fox Posted March 25, 2006 Share Posted March 25, 2006 That looks a lot better. But this one looks too...matted, too...flat. Link to comment Share on other sites More sharing options...
Worker 11811 Posted March 30, 2006 Author Share Posted March 30, 2006 Two more tribbles: Pretty much started over from scratch on these. 100,000 hairs rendered. (As much as the computer will do.) Length is 50. 1% randomness of length. Fur Ball #3 This one is exactly the same as the one above except it's got 2% gravity added to make the hairs fall down just a little. Fur Ball #4 Link to comment Share on other sites More sharing options...
Fox Posted March 30, 2006 Share Posted March 30, 2006 I think the 2nd one is more convincing. Link to comment Share on other sites More sharing options...
