Create and Simulate a Procedural Rope

Today we’ll create a procedural rope and simulate it using the grain solver. There are always many different ways to achieve stuff in Houdini. In this tutorial I chose the VEX route to generate the rope. This gives a nice self-contained node that can easily be turned into a digital asset. The procedural rope is then deformed to a simulated wire using wire deform. Download end file

Crochet – Blending between Delaunay and Voronoi

Crochet-Blending-between-Delaunay-and-Voronoi

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

Nerd Rant: Render Engines

Nerd-Rant-Render-Engines

There are many render engines out there nowadays and it’s not easy to choose the right one. CPU or GPU, biased or unbiased. In this video we discuss the pros and cons of different render engines from our humble point of view. As a bonus we talk about LUTs and view transforms.

Nerd Rant: Hardware – DIY vs. Pre Built

Nerd-Rant-Hardware-DIY-vs.-Pre-Built

This is an experimental post. As we often sit down to discuss different topics from our Entagma life, this time we just switched the camera on and created a vlog-type movie for you. Just the right thing to watch on a otherwise boring “no-new-tutorial Monday”. After Mo’s post about building his own workstation we started to discuss further what the best strategy is to acquire a machine for GPU rendering. Buying off-the-shelf hardware has advantages, […]

Low Poly Transform

Low-Poly-Transform

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

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.

Directions From Growth

Directions-From-Growth

When dealing with growth solvers, often you not only need the growth itself, but a direction vector. For exapmple to copy feathers onto a surface, or other directed object, like knitting loops. In this tutorial Manuel explains how to calculate direction vectors on the surface by using the gradient.

TD Essentials: Parallel Transport

TD-Essentials-Parallel-Transport

CCurve framing is important for a lot of things, like trajectories, creating geometry from curves or aligning copied geometry to curves. In this tutorial Manuel implements the parallel transport algorithm that transports an initial normal vector along a curve to create a smoothly varying frame. But be warned. This video is very VEX heavy.
