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.

Quicktip: Signed Distance Outlines

comments 11

Signed Distance Fields are very versatile. In this installment of the Entagma tutorial stream, Manuel shows you how to use a SDF volume to create outlines around an arbitrary object. By remapping the values from the SDF using functions like sqrt() and sin() it’s easy to create propagating ripples.

Procedural Modeling Of Water Droplets

comments 6

If you want to make your product appear nice and fresh in your TV commercial, chances are that you’ll put water droplets on it. This effect is very popular in advertising. In todays installment of the Entagma tutorial stream, Manuel shows you how to procedurally build such an effect in Houdini.

Modeling and Rendering a Quartz Crystal in Houdini 16

comments 23

When testing out a new render engine (or any tool that can do rendering), one of the typical objects I try to get a decent image of is a quartz crystal. In order to get that right, a rendering needs to contain effects such as dispersion, proper refractions and SSS. In this tutorial I’ll walk you through my first attempt to render a Quartz in Mantra in H16.
