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

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

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.

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.

Live-Rendering-Of-Heightfields-In-Redshift3D

Heightfields are a nice addition to Houdini 16 for environment work. They more or less replicate the functionality of programs like Worldmachine. In today’s tutorial Manuel shows you how to create a terrain from scratch in Houdini and how to render it directly in Redshift3D, without baking out textures manually.

Scaling-The-Bullets-Dynamically

Today we scale live dynamic objects and make the scaling affect the running sim. You’ll gain some insights into how the Bullet solver inside of Houdini works and how it operates more efficiently using packed primitives. Manuel goes over the ins and outs of modifying a Bullet sim dynamically.
