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
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.
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.
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!
