In Houdini, you can create engaging animations using the Wrangle node and VEX scripting to add dynamic effects to polylines. By leveraging the curveu attribute, which represents the position along the polyline, you can introduce a subtle yet captivating "giggle" effect to the middle of the line while keeping the ends stationary. This effect adds a sense of organic movement and life to the polyline, making it appear more natural and interesting. By adjusting parameters such as intensity, frequency, and damping, you can fine-tune the giggle effect to suit your animation's needs, allowing for a wide range of creative possibilities.https://www.patreon.com/posts/dynamic-polyline-104411447
