1. ## The Cube

Hey all, I got super excited on this image and started to make something based on it And now I'm reaching out for some guidance. Attached is where I was heading... still not getting the nice symmetry and variety that the image has. Any help would be appreciated thanks! cube_v001.hipnc

3. ## Recursive Subdivision Algorithm: Morphing any Shape into Fractal

Hello everybody, I’m relatively new to Houdini, and as part of a personal project (a short film), I’m currently trying to reproduce an effect based on the recursive subdivision of a surface. We can observe the said effect for instance on this video made by Simon Holmedal : https://www.instagram.com/p/BK8ivNajNdu/ The different iteration (non animated) of the algorithm can be also observed on this video : https://www.youtube.com/watch?v=HHKPdf67Sfo Or on this one : https://www.youtube.com/watch?v=K1mlO2YSfU4 It is also the same effect used in the official SideFx Ident (Simon Holmedal again): https://vimeo.com/164501803 I searched every topic on OdForce which seemed to deal with this technique, I found several topic like : • http://forums.odforce.net/topic/28803-this-subdivided-thing/ • http://forums.odforce.net/topic/28161-triangle-polygon-morph-animation-to-fractal/?tab=comments#comment-160368 • http://forums.odforce.net/topic/26779-how-to-creat-subdivision-pattern/?tab=comments#comment-154625 And also the famous tutorial by Entagma regarding subdivisions : • http://www.entagma.com/loops-subdivisions/ Those topics seem to give several techniques to subdivide a surface into smaller triangle, but none of them propose a solution to actually animate the subdivided mesh. It seems that the overall technique is based on a recursive subdivision, coupled with the fact that the subdivided parts move along their normal, in order to give this effect of extrusion and fractal. I’ve also searched more deeply into the code of such an algorithm, and I’ve found several websites (with code) explaining this effect: • http://code.algorithmicdesign.net/Recursive-Subdivision-Mesh • http://atlv.org/education/ghpython/#7 • http://www.geneatcg.com/2014/11/21/rhino-python-tessellation-subdivision-first-version/ • http://www.geneatcg.com/2014/11/28/rhino-python-mesh-boy-surface-subdivision-analysis/ There are also other websites (less significant) dealing with this issue: • https://codequotidien.wordpress.com/2011/07/18/half-edge-mesh/ • http://www.wblut.com/he_mesh/ • https://codepen.io/anon/pen/YEyYZv • https://wewanttolearn.wordpress.com/tag/mesh-recursive-subdivision/ That’s all I found regarding this effect. Does anyone know how to make this kind of animation? If so, could anyone post a Houdini file which implements this technique so I could learn from that ? Thanks by advance, I hope someone here will know how to resolve this issue !
4. ## Triangle polygon morph animation to fractal

Hello everybody, I'm trying to figure out an effect done by Simon Homedal, here are pics of the process, seems to be a subdivided triangular mesh that animates into infinite fractal, could be this done subdivisions, extrusions, blend, for each loops and solver? if so, how can you manage so houdini doesn't crash when getting smaller? putting a end value on the for each node? I watched Entagma video on fractal and for each divisions, now I'm trying to figure out how to combine all this stuff. Reference pictures: Here is the video (second 0:28) Also Simon kinda explain the method on IAMAG 2016 Class at min 32:20 He said that he uses a polygon, subdivided, and then animate with a blend shape, then build all the stuff from there, the screen record is available at u\$d 100 but he only shows 2 quick houdini screens so its kinda expensive for that amount of info in my opinion (althoug the overall talk is great) . At 34:20 is a similar effect again with a sphere Any info will be great, in mean time will keep thinking and playing with houdini. Thanks!
5. ## meshing fractals

this i am starting new Project: meshing fractals into real Geo. Last year, i've to created "fancy 2.5D" splines fractals. this year i bringing it to "3rd Dimensions". this are basic primitive rendering which i plan to use in huge scene. goal : manage Billions of polygon's / Data in a efficient way. the final scene will 1000 times complexer Geo. this are simple Geo / renderings:

Hello everyone, does anyone know how can I shade a fractal shape like this on the picture with houdini mantra?? Thank you.
7. ## Rendering Fractal Clouds

Hey , i've made the cmivfx houdini fractals tut and made clouds, but i'm having problems with the rendering time. can anyone help me with that?
8. ## hollow volume - Fractal Cloud wrapping a sphere

Hello, I am new to Houdini, and have just finished the cmiVFX tutorial on Fractal Clouds. I would like to create a cloud layer which surrounds a small planet. Would anyone suggest ways of doing this? Basically I would like a hollow volume sphere, and the capability of using a volume vop with this sphere. Should I be doing this at the object level or within the volume vop? (Probably either are possible?) It would be great if I could move the clouds around the sphere as well, so the hollow wasn't just a cut out of the rectangular space, but so the clouds can actually wrap around the sphere. Any help or suggestions would be appreciated. Thank you for your time.
