  1. I started using Houdini about 2 years ago, recently I have felt a desire to not only share but, hopefully to open up a discussion about the explorations undertaken in the work. The first post is therefore a look at how it began. 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. The video and images below are examples of the earliest explorations (and failures) of this theme, first applied to a modelled object, with the video then moving onto a landscape: https://vimeo.com/376861116
  2. Hi all, I've been practicing and experimenting with VEX in Houdini and I challenged myself to see how far I can go with only VEX and VOP. I did successfully manage to create this simple effect without any use of dynamic simulation (DOP). https://vimeo.com/375250070 Basic Summary: A particle system that computes at frame-basis. I can jump from frame 1 to 700 without waiting for simulation. Instead of the traditional age/life computation, this system uses travel speed to compute. Trajectory generated with polar coordinate + Flow Noise on sphere section. The graph mainly consist of VEXs. There's still room to be improved definitely, if anyone is building more upon this, please share it, would love to see it. I think at the end of the day, this kind of system is probably not entirely practical tbh, but it's a great practice and study on coding with VEX. (SHOUTOUT to a best friend of mine who's studying mechanical engineering, helped me to find a way to calculate the spiral length.) HIP file here: FX_Rasengan_v01.hipnc Happy Coding!
  3. Sketch and etch style

    Like everyone else, I use a bunch of tools for my work. But I found myself using Houdini more and more for 2d work, including making a sketch or etch style of pictures like these. I did it using sops, and while I imagine there is at least a million ways to do that in Houdini, it was bloody fast, took just a few nodes, and with plentiful variations.
  4. Hello everybody, I've got some questions for you. I am soon going to start a new project on Houdini and I need a lot of documentation to have a good start. I want to do a procedural apartment with a defined boundary. The number of rooms can be changed as well as their shape and in the end there will be furniture which will stay in a defined room. If you know of any websites, videos, pdf or even hda wich could be related to all of this I will be more than happy to study them. Thanks in advance for your help ^^
  5. Poly Carve SOP

    http://www.patreon.com/posts/31506335 Carves out polygons using a point attribute with the ability to define the carve values per primitive using primitive attributes. Pure VEX implementation, 10x faster than the default Carve SOP (compiled). It preserves all available attributes. It supports both open and closed polygons.
  6. Houdini to maya

    Hi, Is there any way to export from Houdini procedurally and working in Maya with that model, I heard that procedurally doing this way doesn't give any issues and works fast in Maya while working with large super sets or even smaller one... I wanted to model a super set in Houdini and import in Maya and shade, light it... Please text If you do any exports from Houdini to Maya...
  7. Hello, my name is kalata and I am an experienced Houdini Artist. I also have solid experience in 3Ds Max, Nuke, After Effects and Photoshop. You can check my demo reel here:
  8. Hi all I am currently working on a feasibility test in order to build up some understanding of procedural modelling, I have a question regarding expressions in Houdini today, I have received great help from artists in the community which I am very grateful for, thus has helped me get this far, the new question I have is, I would like to delete all the lampposts based on the location of a building box I am using to represent a futuristic house, this box will be a model of a house and will have details like windows and doors later on, with this in mind, am I better of using a proxy box over my model which deletes the lamppost inside the box's radius or is this possible with the actual asset itself?, I have attached an image of what I mean including the current expression within the delete node thank you . Kind Regards Ahmet.B
  9. Rope bridge procedural

    Hi, I'm working on the most original project never did in Houdini before of a procedural Rope Bridge. I have to say thanks for all the help I have found in this forum and now I would like to share with you my progress. (In the description of the video you will find the HIP file) https://youtu.be/kILUeVOmAig
  10. Procedural Armour generation

    Hi, This is going to be my next training series. Procedural armour generation in Houdini. There's still a lot of work to be done. I need to detail the torso, the neck and finally build a head gear. But it's coming along fine, so I figured it looks decent enough to share.
  11. Looking for text animations

    Looking for a talented Houdini artist who can do procedural text animations. We have an upcoming project that requires it. The resulting geometry should be dynamic, procedural, however, lightweight as it will be baked out and used on mobile devices. Please include links to any work you have done in this area, as it will help us filter down the candidates. Thanks!

  13. Hello everyone, Recently I tried to create a completely procedural building, which at the same time is ready to be destroyed with Houdini and this is what I ended up with. https://vimeo.com/355676432
  14. Recreate a beautiful thing

    Daily greets, houdinistas! Any idea how to model something like this? https://www.artsy.net/artwork/matt-shlian-omoplata-5-blue-test I mean this detail, particulary
  15. UPDATE An update on this project... The procedural tool is complete and my first space station is done! Now to blow it up and crash it! Here is a proper presentation of the tool You can also check more details, and some high resolution pics, at my artstation page: https://www.artstation.com/artwork/v1X09v -------- I made a tool that can be used to create space station modules for production of VFX. Basically all geo is water tight and easily subdivided and ready for Mari or Substance Painter... I didn't made the textures procedurally because I feel the hand touch in textures would add realism to the objects. The tool is 95% ready I feel but I am in the process of making my first Space Station... here are the samples: HDASample.mp4 And first render test:
  16. This is my second Course, its available now on CG - Circuit. Link: http://bit.ly/2xk1Lzj Procedural Hardsurface Design in Houdini In this course I will show you different ways in Houdini about procedural hard surface design. The first chapter is about the Voronoi node and how to create different patterns with it. The second chapter deals with a simple hard surface tool to use the existing topology for creating new surfaces. The third chapter will show you how to use noise as a panel generator. In the fourth chapter we will build a greeble solver to refine large structures. The last chapter is about the process of a procedural robot that is made with different shapes and lines. Each chapter includes some RnD rendering in the end. I'm glad to share this knowledge with you! See you in the course! For this course you need a basic understanding of Houdini and rendering with Octane. All project files and the low poly character are included. Have a nice day and enjoy the course! timcgi
  17. Procedural Fractal Spiral

    Hey guys, I have been scratching my head for a while with this. I've researched online, tried to use geometry deformers, attempted boolean operations with concentric spheres, even migrated to 3ds max because I remember some modifiers that created similar effects. I've had no success and I am a bit desperate. I want to understand the system at play in the images below. I hypothesize that you start with very simple geometry, namely some parallel planes that then are deformed to achieve this amazing effect. My other idea, as I explained earlier is to create concentric spheres that are then "cut" by a solid geometry that has the inverse of this shape. If any one has any tips, pointers, references or resources that could help me figure this out, it would be much appreciated. Thank you so much in advance for preventing more hair-pulling. Cheers, Bruno

  22. Ball(clew) of wire

    Hello, there is a task to make a similar ball of wire (the wire fills a limited volume, keeping in turns), ideally animated (show how it roll up) What i want to get: I achieve this result (far from optimal, using popinteract with popnet): As I understand it is necessary to move towards the simulation of the rope.
  23. Procedural Modeling Advice

    Hey guys, after exploring most sides of Houdini, I'm surprisingly trying to settle on Procedural Modeling as my main focus :D I know it's a bit weird since it's not Houdini's strongest tool, but before Houdini, I have tried Modeling in Maya and Cinema 4D and failed, but with Houdini, it seems so logical and straight forward to my mind. I'm trying to get a job as a 3D Modeller using Houdini here in my country (Egypt), and i need some professional expert advice from you guys on some points regarding the market and Modeling in general (worldwide not just a specific country): 1- Is Houdini used widely in Modeling in the market or not yet? and why? and how much is Procedural Modeling popular nowadays in Games and Film as well? 2- I dunno much about texturing and I'm planning to learn a texturing software besides Houdini, so far I'm choosing Substance Painter, do you guys have any advice regarding this part? 3- Is Mantra good enough for me? Or do i have to dive into other renderers later? 4- How to constantly learn and upgrade myself in the right path? What else to learn? If you can give me advice from your professional experience, that would be great. 5- Any other advice you could give me is welcome, even abstract ideas, anything really. 6- One last thing There are different ways to approach Modeling in Houdini, i know that all methods are correct, but as a professional, do each one have like a standard method to approaching weird curves and irregular shapes efficiently? or you mix and match different approaches? Do you usually do low polygons baring in mind to subdivide the whole thing in the end or you can just model it all high quality from the beginning? I mean, how do you think and set your mindset before starting your work? :D Sorry for the long long post, appreciate your help guys. EDIT: I'm not a newbie who wants to explore Houdini, I'm already familiar with it and with all the resources available and I spent some time learning it. I'm seeking professional advice from experts because I'm applying for Modeling Jobs these days and i have 0 working experience in 3D.
  24. Procedural Scale

    Hi Everyone, Question Time! I have a curve in a helix shape. It has been made procedurally so the number of coils and length etc can be modified I would like one end of the helix to be stretched out more. Is there a way of procedurally scaling a part of a curve perhaps with a ramp? Any thoughts would be really appreciated! Thanks!
