cellchuk Posted July 13, 2007 Share Posted July 13, 2007 How would you grow a parasite ? Hi, - I am going to "try" to create an organism which is something like parasite or some kind of fungi [located on trees] - The thing is that before I get started working on this effect, I wanted to take some advices and suggestions from you guys who are interested. - I was thinking about using L-Systems to get the effect but I am sure that there are other ways too. - I also will need to create a custom shader in VOPs to get the realistic effect. Any Suggestions, Ideas, or references about how to create the system and the shader would be appreciated. Thanx in advance. * I am putting some references to illustrate the effect that I need to achieve.

rdg Posted July 13, 2007 Share Posted July 13, 2007 (edited) How would you grow a parasite ? good question! Looking forward to see you approach. You mind if I grow something on my own? Need to get rid of these boxes somehow ... Maybe this book helps: http://www.amazon.com/Growth-Form-Complete...6891650-2892932 Haven't read it, though.

rdg Posted July 16, 2007 Share Posted July 16, 2007 You maybe want to take a look at non-newtonian fluids http://www.everyoneforever.com/content/200...wtonian_fluids/ Georg Quote Link to comment Share on other sites More sharing options...

jhiggins Posted July 16, 2007 Share Posted July 16, 2007 as far starting with this, i would go old reliable metaballs, lots of them!! animating the weights and converting to geo once you've gotten you're shape right!! good luck! Quote Link to comment Share on other sites More sharing options...

Thanks for the tip jeffrey. I am gonna try animating the weight cheers Quote Link to comment Share on other sites More sharing options...
old school Posted July 17, 2007 Share Posted July 17, 2007 Looks like branching structures to me = lsystems or trailing particles. Quote Link to comment Share on other sites More sharing options...
cellchuk Posted July 17, 2007 Author Share Posted July 17, 2007 Looks like branching structures to me = lsystems or trailing particles. at the moment I am experimenting with l-system But u r right trailing particles will also work I am gonna give a shot. apart from that the shading scares me a little bit. because I haven't touched subsurface scattering before. need to check the sss posts cheers Quote Link to comment Share on other sites More sharing options...
jjstanley Posted July 17, 2007 Share Posted July 17, 2007 For the shader you may want to look at some of the wrok by the winner of the last Houdini contest, Serg. You can see his project at http://www.sidefx.com/index.php?option=com...opic&t=6420. He had some great ideas that may come in handy for you.

He had some great ideas that may come in handy for you. thanks jjstanley, I have already checked Serg's sss solution and its really clever [ respect ] at the moment I am doing some experiments with Mario's SSS shader which is perfect. Besides, render times are a bit heavy so maybe I might need to use Serg's solution. By the way I am using Marc's [correct me if I am wrong] pcplastic shader as well, which helps a lot with the internal colours Thanx again for the link ------------- this is the first shading test. cheers Quote Link to comment Share on other sites More sharing options...
rdg Posted July 18, 2007 Share Posted July 18, 2007 ading test. Looks good! Georg Quote Link to comment Share on other sites More sharing options...

stevenong Posted July 18, 2007 Share Posted July 18, 2007 I think that will be Mark Elendt's pcplastic shader. Cheers! steven Quote Link to comment Share on other sites More sharing options...

cellchuk Posted July 20, 2007 Author Share Posted July 20, 2007 SEQUENCE TEST - Flicker Hi, I made a sequence test with Mario's SSS shader. However, it is somehow flickering. looks like a lighting artifact but the light is fixed I think the Problem will be point cloud sequence I am posting the parameters, light position and the video. If anyone has an idea what the problem is... need help cheers Flicker Artifact !!! - Video File flicker.mov --------------------------------------- SC_Shot_01 --------------------------------------- Shader Parameters (MultipleScattering) --------------------------------------- Shader Parameters (SingleScattering) --------------------------------------- PointCloud Parameters (Cloud Generation) --------------------------------------- PointCloud Parameters (Density Estimate) Quote Link to comment Share on other sites More sharing options...
