Crochet – Blending between Delaunay and Voronoi

comments 6

Here at Entagma we love to deal with yarns. This video extends the “yarn-effects” with a crochet approach. Using the delaunay triangulation of an input mesh and its dual diagram, the voronoi mesh, we build a procedural model that uses point color to blend smoothly between the two. That gives an intricate pattern, especially in the blending regions. As a bonus we animate the effect. Download end file

Low Poly Transform

comments 9

Blending smoothly between a high-poly mesh and its low-poly representation is a subtle but useful effect. In this tutorial you’ll learn how to create two versions of the same object, one smooth and one facetted, with the exact same topology. This enables you to blend between the two using a falloff value.

Differential Mesh Growth

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.

Differential Line Growth

comments 27

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!

Houdini: True 3D Reaction Diffusion

You might have seen this effect more frequently during the last months: Those growing organic blobs that cover a surface in intricate Patterns (sometimes resembling the texture found in a Keith Haring painting). These patterns are the result of a process called Reaction Diffusion.
