We made it. Up and running. Was about time. Entagma is our collection of stuff (a.k.a. resources) that we’d love to have known when we started diving into certain advanced areas of 3D computer graphics.
We are amazed. We’re amazed by the feedback we got from you during the first months of Entagma. We’re amazed by the wealth of your artwork. We’re amazed by your enthusiasm. Entagma has come to be everything that we hoped for. And more.
One of the great things about the Houdini community is that we’re always confronted with clever questions and with clever answers too. “How do I color strands using an image’s color palette?” was the comment on Vimeo that led to this setup. Yet when talking about coloring polylines we also need to discuss rendering them.
Deskriptiv (http://www.deskriptiv.de) inspired me very much over the years, with their unique mixture of intricate setups and beautiful design. In this tutorial I want to show you how to rebuild one of their creations “Double Mesh” inside Houdini. “Dual Mesh”, the Houdini variant, is an interwoven sculpture made of a Delaunay mesh and its dual, the Voronoi graph. Using mostly standard SOPs this video is a lesson on creating real world setups in Houdini, quickly. Additional tweaks like variation on the thickness and bulging through the use of noise, etc. can be found in the demo file that you can download below.
We’ve been visiting Ars Electronica this weekend. It was amazing. Such a weird and wonderful collection of modern nerd art presented in an astonishingly creepy environment. (Think nuclear shelter underneath an abandoned logistics center). What that meant however is that there was only very little time to record a tutorial. That’s why this ended up being an extremely quickt tip.
The “Spline Wrap” deformer inside of Cinema4D is a versatile tool that many artist use on a daily basis. Whether you want to wrap paint strokes along a spline or animate a snake, the defomer gives you a quick and easy way to do so. Houdini offers a similiar tool with the “wire deform node”, but it’s a little more versatile and thus a little more complex to setup. So having a counterpart to the “Spline Wrap” deformer might be a good idea. In this tutorial Manuel goes through the process of rebuilding the C4D tool inside Houdini. This is a good exercise in how to use Houdini to create tools and offers some matrix math, too, as a bonus feature. Enjoy!
As some of you already found out, it is quite possible to set up differential growth not only on a line but also on a mesh. This tutorial goes into the details of doing exactly that while allowing for some degree of art-directability (is that even a word?) of the growth patterns.
This is a classic effect in Houdini. I stumbled upon it over at Odforce. As you will see from that thread there are many elaborate ways of achieving this kind of growing curve. However we’re gonna build a very simple version which yet offers a nice way of controlling growth by passing along values from a noise field. Hope you have fun!
In this quickie we’ll go over how to turn standard voronoi cells into something alittle bit more organic. We’re going to use a combination of standard SOPs to quickly build a versatile procedural setup which allows you to create a plethora of different patterns.
Rrecently two projects caught my eye – one is called “Subdivisions” by Adam Heslop, the other one is the new SideFX Ident by Simon Holmedal. Both employ (as far as I can guess) a technique to subdivide a selected part of a mesh over and over. In this video we’re gonna set up a simple version of a similar algorithm. Also included is a neat trick how to efficiently render splines in Mantra.
The Mandelbrot set – the mythical King of fractals. The one that started the whole fractal craze in the 80s and 90s. In this video we’ll implement not only a classic Mandelbrot set that will yield the omnipresent image of that weirdish ridged shape, but we’re also gonna build a setup that will allow us to generate a 3-dimensional realtive of it: The Mandelbulb.
