  1. Nekiya

    Hello, I'd like to share a shortfilm that I've been working on for the last few months. It is set up and rendered entirely in Houdini; whilst some 3d models are drawn in other bits of software, the majority is procedurally drawn and the outliers also tend to undergo transformations. Strictly no 2d effects, everything is simulated spatially within the scenes (this is part of an ongoing practice ethos of trying to understand all geometry in 3d and render a fully composited shot). I am very excited to continue to develop and unpack a lot of the systems that have been built for this project. It would be great to get some feedback, thoughts and criticisms from this community. I hope you enjoy. LINK: https://vimeo.com/446918887 Cheers, Egmontas Description: Nekiya is a short film that constructs a spirit realm as a reflection on the naive hypothesis for the existence of ghosts. Who has seen the spirits? Neither I, nor you. But when the invisible weighs upon your chest, the spirits are reaching through. Let the spirits emerge and let Spookiness be true. As Spookiness has an overwhelming desire to meet Soba, she anxiously struggles to determine her place in this delicate world full of occurrences at the edge of her perception and control. Soba begins to doubt the verity of not only her constructed memories, her tears, but the seemingly indeterminate nature of her body itself. Spirits emerge as three-dimensional entities with embedded spatial, material and behavioural data that characterises their potential and inherent constructional capacity within what we can now determine as our multiple realities. These spirits are a consequence of procedural logics that inform both simulation and translation in a digitally pliable universe. Nekiya is the hypothesis of a haunted space of spectrality; it is an episode in the search for a practice of digital poetics.

  4. How to procedurally flatten the bottom of a sphere. Just an idea can be very helpful here. I have been trying bbox (min, max y-components) in a vop over points, haven't been able to achieve.
  5. Spider web ground cover

    Any suggestions on the method to be able to achieve something like this?
  6. Procedurally split faces

    Hey guys, it's me again, I have another "complicated" question : is it possible to procedurally split faces with vex ? I'm modeling roofs, and I needed to split the top faces to get to and be able to get a triangle shape (by translating the created point on the Y axis). The edge divide sop makes a wonderful job, but sometimes it doesn't cut faces properly (it's very rare but very annoying). For now, I detect the bugged faces by counting the vertices on each face, and if one has 6 vertices then it's a bugged face; but I don't know how to split them procedurally. One method that came to my mind was making a python script that creates a polysplit node for each face with the split coords but it's not very efficient.. If anyone has an idea ! Cheers, edit : added a screenshot for a better explanation!

    Hi guys, i would like to procedurally do this bathroom wall, but i'm stucked.. I used for each loop but i can't get random edge for each wall of the room.. Thank you for help.
  9. I've been learning a lot of vex over the past couple of months and this is my first real practical use trying to make a procedural tool. Let me know what you think! Next iteration is to add more curved lines using trigonometry instead of smooth. https://youtu.be/UsDpGrcrLhE

  11. Digisoup

    Hello, I thought that I would share a side-project I started this last month because I lost a bit of steam (no pun) and thought that it would be curious to receive some feedback. The Digisoup began as an idea to create a procedural recipe that creates and fills a bowl of soup with various ingredients. The initial to do: bowl, stock, dumplings, veg, seasoning, steam, etc. The bowl or vessel was modelled independently but used as a source object for the other ingredients. Spring onion, spices, chilli, dumplings, eggs and noodles have all been drawn within a procedural framework - I intend to do posts explaining each ingredient if anyone is interested. The stock (liquid of the soup) is primarily a shading exercise, and on that note all of the shaders are also procedural and do not utilise bitmaps or external references. The intention with that was to be able to control 'fattiness' or 'richness' of the soup we are about to enjoy. I haven't yet documented the entire process but here are some of the shots I've managed to salvage while working in progress. At some point the project began to evolve into figuring out the context around the bowl with some embedded procedural tricks - I will expand on this later! Would love to hear your thoughts! Cheers.
  12. Hi everyone, I'm trying to do something quite simple but i'm struggling with it. I have an imported pile of sticks, i want to take this pile and copy each stick to a different point on a grid, i know how to do this using the method of having each stick have its own geo node and pluging those into a switch and copy stamping them onto a grid, but i want to achieve this result without having each stick be its own node, as there are 214 individuals this would make for a very crowded network. Could anybody help me out? I have attatched my current set up, I am guessing I need to specify in the copy stamp that for each point it needs to select one of the 214 points which are being fed into it, but i'm not sure how to command this expression? Thanks in advance! Dbrs_wood_twig_T_rfkkwaa_LOD0.obj
  13. Subdivision fractals

    Hi, I tried replicating this type of "subdivided fractals" and figuring out how does it exactly works for 5 months now but with no success despite my best efforts. (this is the thing I'm talking about: http://www.michael-hansmeyer.com/platonic-solids , it is somewhat explained in the technical background tab, and a bit more info: http://www.michael-hansmeyer.com/subdivided-columns) I tried similar things with the kinds of smoothing algorithms mentioned on the website (Catmull-Clark and Doo-Sabin) but I never achieved anything like these things (or I jusk can't see a forest because of a tree in front of me after that much trying ) So if anyone has some info about how these fractals can be made in houdini I would be really happy to read it
  14. Hello, we are a small London-based startup just about to launch our product next month, which will offer our clients a set of 3D customizable models. At the moment we are looking for an Houdini Artist capable of creating a digital asset of a low-poly rocket, so that it can be customized. The 3D model itself is very simple, but need some attention on setting the right constraints so that it doesn't break when playing with the parameters. Also, it needs to be 3D printable so some understanding of the common issues that comes with 3D printing would be beneficial (wall thickness issues, non-manifold geometry, etc.) This position is no longer open.

  18. Photoreal Honeycomb help needed

    Hey ya'll, So I've been working on this photoreal honeycomb for a project and I'm not happy with the amount of detail I'm achieving. I'm relatively new to Houdini and I've been trying to use it as a Generalist package however as soon as I have to use any code I start to feel out of my depth. In saying that, my current solution is almost all procedural and all with nodes and no scripting. I have opted for using attribute noises and point VOPs to generate roughness, displacement/surface noise as well as using shader displacement/normal noise to get High frequency noise without having an insanely heavy mesh. I should mentioned I am using redshift to render currently. So my main question is how can I make this look more detailed and more photoreal? (I have provided a render of a test section as well as photo reference of the detail level I would like to achieve.) That test render is the starting point of a camera animation, so that is as close as I intend to get to the honeycomb. I was wondering if I should use a solver to get an organic growth effect or maybe a volume vop? I have tested a volume VOP set up with no luck. Also I find my shader in redshift gives me a plastic look with too much sheen and the normal/displacement looks fake but I can't get it looking better. Any suggestions would be greatly appreciated as I feel I've reached the edge of my knowledge on this. As mentioned I am currently using Redshift, however if someone has a Mantra solution that works well I would be happy to look at that too. I have provided a hip file with the dome light HDR and the mesh cache as well for simplicity. Annnnd this is a small section of the actual amount of honeycomb needed, the actual size is probably 10x that section. Thanks in advance for your help!

  19. map uniform pattern on a geometry

    Hi, I have been looking for a way to create a model that has a certain pattern (like tri, quad or hex - whatever being convex or hole). It is something like this in the picture but the pattern should be all universal in size and shape. (in the picture, the upper part goes smaller and the bottom part being squashed) I understand by doing this, it most likely changes the original shape of a model though. Cheers,
  20. Hi all, Im trying to create damage to parts of the car where I have a tube object and when I move it on top of a surface of the car it will crumple according to the falloff of the tube. I am not doing this by simulation as it is super hard (I dont have much experience in simulations yet). I did try the bullet simulation but no luck and takes forever to simulate. I tried using a falloff node with mountain node on it but it does not push the geometry along the surface direction of the tube. I tried using a attribute wrangler copy and pasted somewhere else but not working.... Im trying to do this in realtime where you move the tube around and it will roughly push and have a noise in the tubes direction but no luck. If anyone can give me a hip sample so I can have a look and see how it is all done would be an awesome help since im still new in houdini. Thanks again in advance I am learning heaps from this community with your awesome works.

  22. Growth Systems

    I originally made a post in in the WIP section, but have finalised a selection of images that demonstrate the extent of the project at this particular time. Hope to get some tips, speculation and direction . The work started with an idea of looking into systems of growth and the procedural simulation of that growth. The question of landscape surveillance and 'fertility' arose - can a landscape (or object) topology be evaluated for growth? In this case the landscape would be a scanned model of a terrain, converted from pointcloud to mesh data and thus reinterpreted as a topology of points and primitives with certain inherent attributes: Position (vector), Normals (vector), and curvature (scalar) predominantly. The simulation can then search for 'flatness' and eliminate areas of surface beyond a limit of acceptability. The surface is then displaced whilst maintaining ties to the remainder, this seemed to mirror a process not too dissimilar to inflation (although much more noisy and undefined), always using the retopologised mesh (and thus recalculated attributes) as a driver for the next frame of growth. Generated or grown form is evaluated through a series of spatial explorations with particular functional characteristics in mind. Much like a single-surface-landscape produces the massing for proposed architectural volumes, these volumes are then reinterpreted as single-surface forms that morph into a typology of architecture defined by certain rules. The primary purpose of the interior volume is to house the program of an architecture. The height of the form is predetermined in the procedural algorithm of massing to produce volumes within a range of heights (for example between 3 and 20 meters). The nature of the form suggests an architectural language of evaluated skin as a means of facilitating architectural space. This is then differentiated to provide for the various requirements of a space of production - for example: how can the floor surface serve as a platform for plant growth; how can the side envelope serve as a mediator of thermal comfort; etc? A. There is a desired differentiation between roof and side envelope - key factors to be considered are the issues of transparency in form for light to enter the space below and the capacity to drain rainwater or melting snow. B. An impression of uniformly distributed structural frames is suggested as a method of holding up a dressing of skin not too dissimilar to ideas of bone to muscle tissue connections. C. The form is interpreted as a skin multi-functional, multi-material character. There is a desire for a thermal envelope mixed with porous characteristics that allow for breathability within the interior environment, light, and mediation from the harsh external environment. The following images are all excerpts of a fully procedural exercise; all grown; but in various stages of development of the same system.

  25. Inspired by a tool done by Simon Houdini I decided to recreate same tool on my way. Basically is a nested boolean system which iterates over itself. Starting from a basic cylinder there are three ways to add detail. First is a cylinder which is usefull to generate pivots or a central hole. Second is a circular array of boxes or a circular curve and third is a ray node projecting points over the mesh and copy cylinders there ( useful to attach bolts, screws or make small holes). There are a lot of room for improvements, maybe is not the most user friendly tool of the world and I should try to find a clearer ways to manipulate the tool. I had a lot of problems adding handles or guide geometries because I didn't find the way to switch the guide geometry to older iterations and things like this. At the end I kept at it was without guides and handlers. Please take a look and test the tool. Would be nice have your feedback and ideas for improvements. The tool can be downloaded from here: https://drive.google.com/file/d/1rDgRtMYhhllZWNdANppqnBo9NahtlZNV/view?usp=sharing Thanks for testing it. O.
